Last month I bought an interesting RGB LED ring from Aliexpress and finally, now, it is here. So that, I’m about to present how I interfaced an STM32 MCU to WS2812B LEDs. This demo uses also FreeRTOS and HAL libraries. I wrote a simple code to make an STM32 interface WS2812B LEDs.
I’ve just realized a digital photo frame with the newly-released STM32F7-Discovery board from ST Microelectronics. A lot of software components are used in this project, such as: FreeRTOS, STemWin (with external resource load), LCD interface.
