Esp32 spi fastled. Has this file been replaced by another file.

Esp32 spi fastled This leads me to believe that it's being bit-banged, and I'm not even sure how to check if FastLED is using any hardware peripherals like RMT or I2S. The APB_CLK the SPI periferial is using is actually derived from the CPU clock. e. 0 fastled-esp32-blink. One of the obvious use cases for this is for FastLED. Currently, SPI Master driver does not support SPI1 bus. ESP32-S3 integrates 4 SPI peripherals. 0 LED output. samguyer LPD8806 - SPI based chipset, very high speed; WS2801 - SPI based chipset, cheap and widely available; SM16716 - SPI based chipset; APA102 - SPI based chipset APA102HD - Same as APA102 but with a high definition gamma correction function applied at the driver level. " I am trying to track down some issues in the FastLED support for ESP32, particularly when combined with SPIFFS (for loading web interface stuff and storing animation patterns). It is worth trying Yve's I2S driver, but its main advantage is the high degree of parallelism, not that it is less susceptible to interrupt problems. Now supported as of FastLED 3. I define the right pins, GPIO14 for clock and GPIO13 for data, but get a compile time warning that "No hardware SPI pins defined. Still see how that devices grow up, they are pretty unstable right now All reactions. All SPI access will default to On most devices, the SPI hardware wants four pins - data in, data out, clock, and a select line. show() in your interrupt routine. SPI0 and SPI1 are used internally to access the ESP32-S3’s attached flash memory. #undef register. For long strings this can take a FastLED version 3. also i tried the FastLED example FirstLight, it did not work. APB_CLK is 80MHz XIAO ESP32 C3 -- WS2812B Led Strip #include "FastLED. TLC5948A that uses a grayscale clock ESP32 is a series of low cost, low power system on a chip microcontrollers with integrated Wi-Fi and dual-mode Bluetooth. New in 3. FastLED is used by thousands of developers, in countless art and hobby projects, and In this video I show how to get an LED matrix working with the ESP32, and recommend two different libraries to show either a marquee or static (not animated) #define FASTLED_ESP32_I2S. I've been working with the DMA controller on the new UNO-R4. }; union The FastLED ESP32 RMT use has two modes: one which uses the "driver", and one which doesn't, and claims to be more efficient due to when it's converting between LED RGB and not. This can run at the 80MHz clock. But I would like to start from the fundamentals of understanding the I/O based on directly setting the right registers. The SPI flash interface on the ESP32 disables all code that is not in IRAM (Would need a change in FastLED and in Arduino-esp32). (SPI_FAST_FLASH_BOOT)" Looks like you have LedsTask() set to run on core 0. fastled-esp32-blink. Thanks so far. But since you have experience with the ESP range of controllers and already have seen what I am trying to achieve, I would like some advice and assistance. addLeds<NEOPIXEL, 6>(leds, NUM_LEDS); } void ESP32 is a series of low cost, low power system on a chip microcontrollers with integrated Wi-Fi and dual-mode Bluetooth. "The ESP32 has four SPI peripheral devices, called SPI0, SPI1, HSPI and VSPI. FastLED is a fast, efficient, easy-to-use Arduino library for programming addressable LED strips and pixels such as WS2810, WS2811, LPD8806, Neopixel and more. I am working with ESP32, Wifi + WebSockets + ArduinoJson + Fastled and experiences crashes also. To use hardware SPI with this fork: Add #define FASTLED_ALL_PINS_HARDWARE_SPI before including FastLED. Espressif ESP32 is recently updated to 2. I am sending instructions from nodejs (what leds to turn on etc) via websocket in json-format. Adafruit's DotStars - AKA the APA102; Adafruit's Neopixel - aka the WS2812B (also WS2811/WS2812/WS2813, also supported in lo-speed mode) - -the spi library for the leds is #include "Adafruit_WS2801. That is the normal approach. For led chipsets that are SPI based (four wires - data, clock, // ground, and power), like the This community is for users of the FastLED library. This library will allow you to: Live play of Artnet stream; Record the stream on a SD card If you're using the Fastled library it will divide the time by the number of pins used A performance comparison of the three most popular libraries for driving WS2812B addressable RGB LEDs. Code; Issues 415; Pull requests 35; Actions; Projects 0; Wiki Since FastLEDHub inherits from FastLED all member functions will be available just like before. This references the standard SPI pins that, again, seem irrelevant and wrong if using hardware SPI Also, within the fastspi_esp32. fully off). What would happen is the ESP32 code wouldn't service the RMT hardware quickly enough, and would fall behind by more than the RST time, so you would end up having a "single line" get broken I am to use the BasicOTA sketch and must include that with my new led sketch. Interrupts are supposed to be very fast FastLED is a fast, efficient, easy-to-use Arduino library for programming addressable LED strips and pixels such as WS2810, WS2811, LPD8806, Neopixel and more. Is it correct that ELast refers to whether the callback is the last one in a SPI transaction? e. 0. Parallel outputs for esp32. 2us (0. h. I have two sketches with FastLED. Steve I'm trying to get the FastLed library working on an ESP-devkitC. h is as follows: #else // Configuration for other ESP32 variants #ifndef FASTLED_ESP32_SPI_BUS #pragma message "Setting ESP32 SPI bus to VSPI by default" #define FASTLED_ESP32_SPI_BUS VSPI #endif #endif. More details on the led chipsets are included on our wiki page. Have a look at the #define FASTLED_ESP32_SPI_BUS FSPI. With 3-wires it won't be bit banged it will use RMT by default or I2S if you I haven't seen a port that uses ESP's SPI interfaces. So: Maybe, maybe not. And I don’t think the FastLED library has good support for ESPs at the I'm trying to get the FastLed library working on an ESP-devkitC. Unless you have deliberately added #define FASTLED_ESP32_I2S to your code to switch to I2S, you will be using RMT for output. – It sounds like you are planning to use an ESP32 microcontroller to drive multiple APA102 LED strands using the HSPI and VSPI buses. I use ESP-IDF 5. After searching a little bit, here's what I found : The pin used to send data to the LED strip doesn't output any signal (I scoped it with an oscilloscope, it stays at 0V). Hello! I'm trying to use a WS2812B LED strip with an Arduino Nano ESP32 but it does not work at all. h, but I'm not sure, I don't work with Teensy) ESP32 is a series FastLED works much better with ESP32. 6k; Star 6. Unfortunately, the fact that commenting out the call to `FastLED. Here's a list of all the LED chipsets are supported. If i include it i get the following errors: ##### TL:DR -- Looking for someone who knows the internals of FastLED library to help me add DMA support for UNO-R4. 3. My understanding is that FastLed has been ported to the esp32, but no work has been done maintaining it for a couple of years. Post by szguyer » Fri Jan 17, 2020 3:29 pm . The library source uses a header file "esp32-hal. from atuline/FastLED-Demos), so it can be handled by FastLEDHub, generally those are the necessary changes you have to perform. SPI bus [VIDEO]. Roughly 230uS at a "20MHz" setting in fastLED. h" i've tried FASTLED with equal wiring before, that was not better. When the I'm trying to get the FastLed library working on an ESP-devkitC. h", which I believe is part of esp-idf but I cannot find. Additional Now supported as of FastLED 3. You can verify if you have done that successfully, but re-uploading BasicOTA Over the air. When I'm not sure about FastLED pins on ESP32 I check fastpin_esp32. h" Saved searches Use saved searches to filter your results more quickly I've been having a really weird issue with my ESP32 and controlling my WS2811 (SM16703P are the chips I have) LED strips. Espressif's current evaluation of FastLED's compatibility with their product sheet can be found here. json libraries. Contribute to eshkrab/FastLED-esp32 development by creating an account on GitHub. 3 Minimal code to get flickering: Code: Select all. Adafruit GFX is 1. , GPIO 13). 9. But, if you do want to use ESP8266, this library works. For testing, you could try something crazy, like replacing the default board definitions (which I think should only be in in pins_arduino. esp32可寻址led灯带库 描述 该库可用于使用rmt外设从esp32驱动可寻址的led灯条。这使rmt外设可以处理所有传输，而处理器可以自由地支持其他任务。 该库当前使用双缓冲来分隔当前正在显示的led灯条和当前正在更新的led灯条。有两个缓冲区1和2，其中包含led灯带的颜色。 Can anyone provide a short sample how to use SPI on the ESP32 chip? Have some WS2812 to drive and some performance improvements would be great. 4 FastLED: 3. The LCD updates just continue fine afterward. We have had a number of reports that our driver (which uses the RMT peripheral to push bits out to the LED strips) produces weird glitchy effects when the program is Im using a ESP32 to transfer the chip contents of a 32MB NOR Flash Chip however the transfer takes over 1 hour to transfer the whole 32MBs i was hoping theres a way to speed it up here my current I am trying to track down some issues in the FastLED support for ESP32, particularly when combined with SPIFFS (for loading web interface stuff and storing animation patterns). You do not have the required permissions to view the files attached to this post. You can still use FastLED to calculate the effects, and then just output to the LEDs with esp8266_ws2812_i2s -- that works, and is rock solid. 0VDC Supplied to the LED array (16x16) I would say "maybe" it's the same flicker. high performance 8-bit math for RGB manipulation, and some of the fastest bit-bang'd SPI support around, FastLED wants to keep as many CPU cycles available for your led I'd have to check the board code used in FastLED, but it appear that FastLED only identifies SPI interfaces based on the board definitions. I replaced the "Adafruit ws2801" library with the "Fastled" library, did not change anything either. Sorry I thought this was an issue with the fact that I was trying to combine FastLED and EspAlexa. DexterHill0 changed the title ESP32 SPI output like a sine wav ESP32 SPI output like a sine wave Jan 2, 2021. Merged Copy link dbu commented Nov 25, 2023. Arduino ESP32 SPI output to WS2801 chip inconsistent. The ESP32 series employs either a Tensilica Xtensa LX6, Xtensa LX7 or a RiscV processor, and both dual-core and single-core variations are available. I decided I'd wait to open an issue until I'd finished my app that communicates via bluetooth instead. regards Dominik. The driver uses the VSPI bus by default (Clock 18, MISO 19, MOSI 23, & CS 5), but can be set to use the HSPI bus (14, And then read about the ESP32 SPI architecture. It uses the I2S (audio) peripheral instead of the RMT (remote control) peripheral (which is limited to 8-way parallel output). The fastled_clockless light platform allows you to create RGB lights in ESPHome for a number of supported chipsets. Reading a bit about SPI and ESP32, it seems that SPI output is actually quite trivial. 8 - Massive Teensy 4. this issue can be closed, it was implemented in #936. This is false, the ESP32 has hardware pins AND I am specifying the hardware SPI MOSI pin my test code: CRGB leds[NUM_LEDS]; void setup() { LEDS. If you want to convert an existing FastLED sketch (e. I am working with sd card also , so how do i use spi pins & extra parallel outputs? Using DMA & i2s ,I think using 16,5,4,0,2 ,3,1 gpio their is possibility to achive virtual driving capabilities for esp8266 May be goio 16 can't work but High performance - with features like zero cost global brightness scaling, high performance 8-bit math for RGB manipulation, and some of the fastest bit-bang'd SPI support around, FastLED wants to keep as many CPU cycles available for your LED patterns as possible Go to FastLED r/FastLED • So i was playing around with the SPI data rates for my ESP32 + sk9822 (660LEDS) project because I was getting some discoloration on the default setting (probably caused by mismatched data and clock cable lengths) and I came across some odd behaviors while doing so. The simple Blink one works, the second only light the bottom few LEDs and flashes the rest once in If you are using an ESP board compatible with the Wemos board (ESP8266 Wemos D1/pro, ESP32 MH-ET Live, ESP32-S2 lolin mini), the SPI connection uses the same pinout location on the ESP board! The pin positions of the LED output may vary. ESP32 is a series of low cost, low power system on a chip microcontrollers with integrated Wi-Fi and dual-mode I am using FastLED version 3. 4*3). Also runs on dirt cheap sub $1 In addition to writing to the LEDs, this library also includes a number of functions for high-performing 8-bit math for manipulating your RGB values, as well as low level classes for I'm using an ESP32 board (Sparkfun Thing Plus) and a ring of APA102 LEDs. 9: 16-way Yves I2S parallel driver for the ESP32-S3. #define FASTLED_ESP32_USE_CLOCKLESS_SPI; #include "FastLED. Later I send 4 bytes ///< GPIO pin for spi data0 signal in quad/octal mode, or -1 if not used. 0 release notes (announcement and the commit log), it seems that release does include improved support for ESP32 variants. This is a driver library for easily & efficiently controlling a wide variety of LED chipsets, like the ones sold by Adafruit (NeoPixel, DotStar, LPD8806), Sparkfun (WS2801), and AliExpress. Unfortunately, the driver only works with the WS2812 protocol. Is it correct that SPI_PUSHR_CTAS(N) returns a value (for SPIX. Steve It seems that FastLED is not using hardware SPI on ESP8266. ino diagram. GitHub Gist: instantly share code, notes, and snippets. Saved searches Use saved searches to filter your results more quickly ESP32 FastLED RMT support . I'm trying to get the FastLed library working on an ESP-devkitC. The code compiles OK as well if the #define FASTLED_ESP32_I2S ESP32-S2 is on the road, is there any plan to support those new ESP32 chip? As title. The sketch compiles OK when selecting ESP32 Dev board as the target. You are not, so you can safely disregard it. GPIO6, GPIO7, GPIO8, GPIO9, GPIO10, and GPIO11 are all unavailable to you. addLeds<WS2811, GPIO_NUM_23, However, I know that FastLED on the original ESP32 is using the Master/Slave Mode transfer for communication to LEDs. (sometimes SPI devices ignore CS pin and occupy SPI) - pins stayed high, LEDs stayed turned on, MAX was outputting 0C and 32F. (Technical reference manual, top of page 40). You can't use RMT with 4-wire because the pins have to be synchronized and RMT doesn't do that. #include <FastLED. Introduction WS2812B Protocol The logic 0/1 is represented by a specific pattern, 0 is a short high pulse and a long low, 1 is long high Contribute to eshkrab/FastLED-esp32 development by creating an account on GitHub. Definitely try the GitHub head of FastLED. This means using the MOSI, MISO, CLK, CS pins. -i am using Dupont jacks so far, will be trying to omit them and solder directly. uint8_t DATA_PIN, uint8_t CLOCK_PIN, EOrder RGB_ORDER, uint32_t SPI_DATA_RATE > CLEDController &addLeds(struct CRGB *data, int nLedsOrOffset, int -the spi library for the leds is #include "Adafruit_WS2801. Of course, the ESP-IDF can provide ready to use complex USB, Ethernet, SPI etc. Not sure if SPI would be fast enough depending on how I do it. The Nano ESP32 category you chose is only for use when making topics on subjects specific to the Arduino Nano ESP32 board. 3k. IO to run on the ESP32 FastLED Package. Using a dual 1:4 demux (74155 and 74373) to drive the additional strands is a viable approach, and it will allow you to control the strands independently and route them to different locations without the need for long data lines.

Hi, I am currently trying to make an LED control with FastLED with my Arduino nano esp32. uint8_t DATA_PIN, uint8_t CLOCK_PIN, EOrder RGB_ORDER, uint32_t SPI_DATA_RATE > CLEDController &addLeds(struct CRGB *data, int nLedsOrOffset, int This community is for users of the FastLED library. The upstream code doesn't seem to use SPI on ESP32 either, so that's just a big hairy todo, and don't worry overmuch. It crashes when fastled. g. show(); is blocking and taking a long time to execute (doesn't seem to me), you're in need of a better library, otherwise it doesn't look like there are any perceivable delays. FASTLED_ESP32_I2S true FASTLED_ALLOW_INTERRUPTS 0 FASTLED_SHOW_CORE 1 Has anyone come across anything like this before? EDIT: I thought there might be an issue with FastLED bit banging on hardware SPI interfering with HSPI, but forcing software SPI with FASTLED_FORCE_SOFTWARE_SPI doesn't change anything Hello after reading the code All SPI access will default to bitbanged output" and after a bit of research I stumbled upon this post #1047 and did what it said and now my question is did I implement it correctly on my ESP32 when the code and message look like this? Code: #define FASTLED_ALL_PINS_HARDWARE_SPI #define FASTLED_ESP32_SPI_BUS HSPI #include This library is a take on the usage of the Artnet protocol to display leds and record on a SD using an esp32 when dealing with a large number of leds (> 800). Has this file been replaced by another file. It seems to run fine until I implement FastLed. I am sending instructions from ESP32 - New SPI Driver for WS2812 chipsets. SPI works on Arduino but it does not on ESP-IDF. Steve ESP32 Core: 1. Note that updating esphome/esphome#4257 to use the new FastLED release may or may This community is for users of the FastLED library. My actual concern is the following: I am using the ESP32 with a small http server hosted, also ESP32 is a battery charge controller and protection host (I2C), Ethernet Phy, and it has to handle hardware interrupts, everything while outputting ws2812 data on pin 33. 3v The SPI flash interface on the ESP32 disables all code that is not in IRAM (Would need a change in FastLED and in Arduino-esp32). 2. The relevant code in fastspi_esp32. I moved your topic to a more appropriate forum category @anon76350110. According to the sourcecode in clockless_rmt_esp32. show(); is invoked; All SPI access will default to bitbanged output I connected ESP32 + 2xMAX3421E and try blik led, whic connected to MAX3421E's GPIO. SPI2 and SPI3 are general purpose SPI controllers. I updated all the pins to my new configuration (missed a few the first time) but when the C3 tries to boot, it gets stuck in a booting loop (see below). ) 2812 over SPI is usually done with a 2. E. I setup SPI by using code below. Wasm. I tried using both FastLED and Adafruit_NeoPixel libraries but the result was the same : no signal at In my implementation you have an opportunity to switch patterns immediately after FastLED. SPI is backed by DMA and is apparently more stable than the RMT driver. A robust and massively parallel-led driver for Arduino/Esp32/RaspberryPi/Atmega/Teensy and more. But now I want to connect a second strip and drive it in parallel to the first one using the second SPI bus (HSPI). So that raises the question, how do I choose to use hardware SPI. A place to discuss and share your ESP32 is a series of low cost, low power system on a chip microcontrollers with integrated Wi-Fi and dual-mode Bluetooth. h> I add them like this, from separate function calls that set nextLED and groupLedCount according to the way the stings are wired up: I found a section where the esp32 data rate appears to be set, it was testing for whether the user is using hardware SPI or bitbang SPI, the code referenced two constants set someplace else. szguyer Posts: 19 Joined: Thu Jan 11, 2018 5:41 pm. About. show()` avoids the crash doesn't mean that the cause is in `FastLED`. Both controllers share the same SPI bus signals, and there is an arbiter to determine which can access the bus. h> // How many leds in your strip? #define NUM_LEDS 3 // For led chips like WS2812, which have a data line, ground, and power, you just // need to define DATA_PIN. lib_deps = Adafruit GFX Library Adafruit BusIO Wire SPI FastLED FastLED GFX Library LEDMatrix [env:ttgo-t1] platform Saved searches Use saved searches to filter your results more quickly -the spi library for the leds is #include "Adafruit_WS2801. 15, but 2. Add hardware SPI support on ESP32 #1047. I know ESP32 has support for multiple SPI channels, but I don’t know if has restrictions on using multiple at once. Install the FastLED Library. Steve If I switch to the non DMA version of pushImage, there's no crash. Well I will try to get into it and create some ESP32 solution for FastLED, but I think I could need some support for this. We have had a number of reports that our driver (which uses the RMT peripheral to push bits out to the LED strips) produces weird glitchy effects when the program is I'm trying to get the FastLed library working on an ESP-devkitC. Generated SPI line 10-20mm -> Doesn't work at all! SPI line 20-40mm -> Works but so unstable (flickering) SPI line more 40mm -> Works good. Another possibility would be running animation calculations on the second core, letting the first core focus on bit-banging. Cables (including ground) should not exceed 15-20cm or it may be necessary to lower the SPI speed. This community is for users of the FastLED library. #define FASTLED_ESP32_SPI_BUS HSPI. I'm using the DemoReel example and it works well with VSPI, but I haven't yet been able to make the example work with hardware SPI. If you haven't already, I'd decode the stack backtrace on several crashes and see if it's consistent and 109 SpiStripWs2812(int pin, uint32_t led_count, ISpiStripWs2812::SpiHostMode spi_bus_mode, ISpiStripWs2812::DmaMode dma_mode = DMA_AUTO) When verifying, about 100 errors are generated - please see the attached file. Enables the ESP32C2 device, as it does not have a I2S or RMT drivers. For led chipsets that are SPI based (four wires - data, clock, // ground, and power), like the LPD8806 define both DATA_PIN and CLOCK_PIN: #define DATA_PIN 23: #define CLOCK_PIN 22 I have some experience with PIC32 register based programming, so I would like to start with the same philosophy on ESP. Re: Impact of concurrency constraints in SPI Flash interface. I've found ntwallace's fork I have got XIAO ESP32S3 and ESP32-WROOM32 units. You switched accounts on another tab or window. ESP32-S2 is on the road, is there any plan to support those new ESP32 chip? @samguyer I need to understand better how fastled works but definitely yes. The new S3 To use hardware SPI with this fork: Add #define FASTLED_ALL_PINS_HARDWARE_SPI before including FastLED. 003 Using an ESP32. For led chipsets that are SPI based (four wires - data, clock, 11 // ground, and power), like the LPD8806 define both DATA_PIN and CLOCK_PIN. FASTLED_ESP8266_NODEMCU_PIN_ORDER did not help. . drivers. PUSHR) corresponding to the number of If i compile the sketch without line 1 "#define FASTLED_ALL_PINS_HARDWARE_SPI" i get the message rearding bit banging and all is OK. Anyway I get the message "No hardware SPI pins defined. will default to the first hardware SPI MOSI pin) /// @tparam CLOCK_PIN - the optional clock pin for the leds (if omitted, will default to the first I'm using pin 2 on the ESP32 for the FastLED data pin, however I'm wondering if the library is trying to also use one of the two pairs of SPI pins on the controller - my CAN chip is being controlled with pins 13 and 14, which are the hSPI pins I've an ESP32 Dev Module (38pin) and I attached an interrupt to the onboard button. First, you need There are two different ESP32 hardware support elements that can be used for APA102/"SPI" based protocols. Me three. To control the WS2812B LEDs, we’ll use the FastLED library. Currently when you call show() the FastLED library blocks while it sends the data out to the LEDs. #define FASTLED_FORCE_SOFTWARE_SPI #include <FastLED. The fork is here. Help your fellow community artists, makers and engineers out where you can. h: #define FASTLED_RMT_MAX_CHANNELS 1. i want to push the button, trigger the interrupt that calls the function in which I turn on the LEDs. The driver uses the VSPI bus by default (Clock 18, MISO 19, MOSI 23, & ESP32 FastLED APA102-2020 LED Example. P9813 - aka Cool Neon's Total Control Lighting Greetings FastLED community! u/Yves-Bazin and I have been working together to incorporate his amazing 24-way parallel clockless driver for the ESP32 microcontoller into FastLED.

Right now, there is nothing special in my fork -- it's all been merged. Arduino IDE is 2. Now, it might have been cleaner to create a subdirectory with nothing but the FastLED-source code, this could be an organizational change the future. 9 with an ESP32 on pin 27. ESP32 FastLED APA102-2020 LED Example. Notifications You must be signed in to change notification settings; Fork 1. Sure enough, the VSPI macro is only defined for boards that have CONFIG_IDF_TARGET_ESP32 defined. h include there are several "ledSPI. I said a bit of bullsh*t above. If I switch to the non DMA version of pushImage, there's no crash. I am stuck at the moment trying to get my code to compile for the ESP32 board that I am transitioning to from I'm also migrating my sound reactive code to the ESP32, so keep me updated if you find any secret techniques. For led chipsets that are SPI based (four wires - data, clock, // ground, and power), like the ESP kept running with fastled performing a default function, but ESP got stuck once json was being parsed (done in the main loop when receiving it via websocket). At the moment, Building the FastLED solution with Platform. FastLED / FastLED Public. 12 // Clock pin only needed for SPI based chipsets when not using hardware SPI. I don't want to use the same bus for the two strips for performance reasons (I'm building a POV project and very high refresh rate is a must; i'm using the new HD107S led chip to achieve these The above image shows how long it took to transmit a 30 LED strip. The ESP32 is a perfect platform for POV project, it's cheap, has a lot of performance, BT and Wifi and so on. edit: turns out the fastLED example codes do not work ether, while the neopixel lib example High performance - with features like zero cost global brightness scaling, high performance 8-bit math for RGB manipulation, and some of the fastest bit-bang'd SPI support around, FastLED wants to keep as many CPU cycles available for your led patterns as possible (A peripheral bus cycle is equal to neither an SPI bit time nor a CPU clock cycle. # The ESP32 could focus on color processing and send the colors over via SPI. A place to discuss and share your addressable LED pixel creations, ask for help, get updates, etc. All SPI access will default to bitbanged output' 157 | # pragma message "No hardware SPI pins defined -the spi library for the leds is #include "Adafruit_WS2801. The down side of that, if I soldering resistor permanently, ESP32 doesn't start. Get a spare ESP32, they are dirt cheap and sometimes the cheap Chinese just die on me. On my old nano every this script worked, but unfortunately it is broken and I wanted to test it on my new esp32 as well. While, on paper, it has 17 GPIO pins, in reality, 6 of these are blocked off from use. -the spi library for the leds is #include "Adafruit_WS2801. The 3 SPI bits comes in at 1. @roblatour, could you try adding the following before importing FastLED. A simple one for testing and a larger one for 'production'. I have got exactly the same problem on both. Post by Coder42 » Sun Jan 07, 2024 4:16 pm . While writing led data only uses the data out and clock pins, on some platforms using the SPI hardware disables the use of the other pins: I submitted a PR with hardware SPI support for the ESP32 last week, would love to know if it's working well for others. Copy link Contributor. Looking at your dump, maybe FastLED is trying to initialize some RMT channels that do not exist? Support for SPI driven TFT screens supported by Adafruit::GFX (like SSD1331 or ILI3941) - marcmerlin/FastLED_SPITFT_GFX Data Line: Connect the data input pin (DIN) of the WS2812B strip to a digital output pin on the ESP32 (e. And also, in first too case to solve that problem, I connected pull-up resistor 220om. h" #define NUM_LEDS 300 CRGB leds[NUM_LEDS]; void setup() { FastLED. No hardware SPI pins defined. But if i roll back a few versions (of my project), the problems disappear. txt Library Manager. Hello, I am transferring a ESP32 WROOM code to a C3. Something about memory I think (still need to investigate this more). I think 3 SPI bits drives a single bit for the WS2812. h the RMT peripheral is automatically used. 5Mbps SPI and three SPI bits to implement one WS2812 bit. Additionally, this concern echoes a comment from @SCarter858 on Dec 27, 2023, which detailed similar inefficiencies and questioned the actual utilization of DMA for SPI communication within FastLED's ESP32 HW SPI support. Super Stable WS2812 SPI driver for ESP32. FastLEDHub just adds some stuff on top of that. Is there some contention between using ESP32 WiFi and SPI DMA? Interrupts don't work well together? Also, if I make the WebServer task a higher priority, it just pre-empts/pauses LCD updates until the Web request finishes. 11. One is the actual SPI hardware block, but an issue is there are only two of them (three but it seems one is almost always in use for flash), so you can't drive too much in parallel. Drop this into the components/FastLED-idf directory. 6. Just tested my new WS2815 12 v LED strip using an ESP32 and this strip works perfectly directly connected to a 3. Radio gets a priority higher than user defined tasks on either core. Is it down to what pins are used, or is there another declaration someplace else SSD1331 (96x64) vs ST7735 (128x128) vs ST7735 (160x128) vs ILI9341 (320x240): (note that the ESP32 was sending ST7735 160x128 SPI which didn't work at all on SSD1331 and not quite on the ILI screen which requires its own protocol) High performance - with features like zero cost global brightness scaling, high performance 8-bit math for RGB manipulation, and some of the fastest bit-bang'd SPI support around, FastLED wants to keep as many CPU cycles available for your LED patterns as possible FastLED version is 3. Steve Maybe use the SPI function in the Fastled library, I had some weird flashes when doing many calls to the webserver. begintransaction()" calls - does that mean I don't need to include the If I switch to the non DMA version of pushImage, there's no crash. 3 VDC supplied to the MCU 5. I use ArduinoOTA with FastLED (along with MQTT and ESPAsyncWebServer) and have never had this kind of crash. 10! Specific features. Radio (used by Wifi & BLE) runs on core 0. It should not be used for topics about other boards that happen to have an ESP32 microcontroller on them. 1. Looking through the code, the default behavior is to use 8 RMT channels, but the ESP32-S2 only has 4 RMT channels. pins 16/17 are SPI pins for PSRAM, and not usable on WROVERs ESP32 is a series of low cost, low power system on ESP32 is a series of low cost, low power system on a chip microcontrollers with integrated Wi-Fi and dual-mode Bluetooth. You signed in with another tab or window. h> // How many leds in your strip? #define NUM_LEDS 48 // For led chips like WS2812, which have a data line, ground, and power, you just // I'm trying to get the FastLed library working on an ESP-devkitC. But skimming through the commits, I didn't see any specific fixes for ESP32-S3. Espressif ESP32 Official Forum. Resistor shouldn't be so big or it will not affect. Cheers, Nils Hello Pete First let me apologize because what I am about to ask is not a Blynk related issue. x86. #define FASTLED_ALL_PINS_HARDWARE_SPI. 003. Everything was measured with a logic analyzer, to circumvent deviations in millis() (because some libraries disable interrupts). You signed out in another tab or window. When I try to set them to any colour they'll just show random colours of ra The ESP8266 is a limited platform in some ways. FastLED port to the ESP-IDF 4. When #define FASTLED_RMT_MAX_CHANNELS 4, there are RMT CHANNEL ERR at What does the "EOQ" in SPI_PUSHR_EOQ stand for? c. ESP32 Core: 1. Both compile without warnings (well, except for one SPI message) or errors to the ATtiny85. Reload to refresh your session. 14 acts the same. h> Also don't call FastLED. Top. FastLED is used by thousands of developers, in countless art and hobby projects, and -the spi library for the leds is #include "Adafruit_WS2801. 1 & 4. If a call to FastLED. There are many projects posted over the web which implement the excellent FastLED library on the ESP12 processor; however For addressable lights, you can use ESP32 RMT LED Strip or for SPI LEDs see SPI LED Strip Light. Second, note that RMT still has to pause and ESP32 Core: 1. The message about bit-banging SPI is only relevant when using SPI LEDs. What does the "CONT" in SPI_PUSHR_CONT stand for / what purpose of ECont? d. show(); returns - there are no loops to wait for. update: Leaving the dupont plug lines out and soldering the wires directly to the board does not solve the issue. Steve 42 // Each color of 1 bit is represented by 3 bits of SPI, low_level:100 ,high_level:110 Hello, I am trying to use FastLED with an interrupt-driven servo library, but the servo seems to jitter whenever the built-in LED (ESP32 Saola dev board) is showing any color except black (i. But reading through the FastLED 3. I'll probably be posting an ESP32 dual core template soon to see if there's any more room for optimization. ewysy nlcn bci zoun zpra yftpbm xzkl akyfjt yzbk aeaf
