Controlling WS2812B LED Strip With STM32

Hello,

I'm new to STM32 and trying to learn exciting stuff. I want to light a single LED from my WS2812B strip.

For example I will choose 6th LED on my computer and 6th LED on strip will light up.

But I'm not sure where to start. How can I access to single LED address? And how to get it work with STM32?

Thanks in advance.

Welcome, @Sadık Özel​, to the community!

The topic of WS2812 has already been discussed here a few times. The thread How to use HAL DMA to generate PWM on P-NUCLEO-WB, for example, also deals with it and refers to a Github driver from Tilen Majerle and an HAL example from Martin Willner.

Maybe that will help you?

Regards

    After several tries I managed to get it work by PWM and DMA. Thanks a lot.

    Of course, the idea of reading the LED's datasheet does not seem obvious?
