In this tutorial, we will interface the WS2812/B LED with STM32. I am going to use PWM with DMA to send the data to the LED..

Esp8266 WebServer using STM32 HAL
we will use the ring buffer to manage a Esp8266 Webserver using STM32 HAL library. Basically, we will blink a LED using WiFi, by creating a webserver.
LED dot matrix and STM32
Now in order to display any character (For eg ‘A’), Think of the Registers from 0x01 to 0x08 as the addresses of the 8 ROWs and we need to turn the respective LEDs ON in each ROW.
