WS2812 DMA library with low RAM needs. Up to 16 paralel outputs and thousands of LEDs on each of them
Welcome. Has anyone tried this library on 16 channels? Works well when set to 5 channels. If more than 5 then 6, 7, 8 is left stuck. And when set...
Hello, Just a notice about a silicon errata from ST for STM32F410 and 411 (and maybe others): using DMA2 and GPIO as done in this project can cause glitches in...
Hello, first of all thank you very much for the post and for the WS2812B_STM32F4 library. I am currently trying to make a port for the STM32F072 but I am...
Hey! I like your approach of using DMA and a timer to generate the signal. However, I cannot achieve the rainbow or Christmas animation with my current setup. I left...
I'm trying to use your code with a Nucleo-F410RB (100MHz). I just have one strip of 3 LEDs so far, to verify that things work. I have the LEDs directly...
Hi there - really enjoyed your material, helps me understand the bit banding features of this processor family. Can you tell me which libaray would best support the STM32F7 (Cortex...
Hi there~ First of all, great library! I can’t wait to to use it on my F411 board! but I got stuck on some little problems that I can’t open...
Per our twitter conversation: /// Hi. It's lot of things that needs to be changed when you choose another timer. My guess is that you need the TIM2 to some...
I am trying to open and build this project on the STM32CubeIDE version 1.14.1 1. Download the project source from your repository 2. Select import project in stm32cube Project Explorer:...
I have a question about the code here: https://github.com/hubmartin/WS2812B_STM32F4/blob/0e47916345becbebc0dad0df188d80d8b8a7991d/Src/ws2812b/ws2812b.c#L315 The first parameter of `ws2812b_set_pixel` is led channel, so the code above should set all channels as the following but not...
