STM32 Library for RGBmatrix

Post by lejaune » Sat Jul 22, 2017 4:10 pm

Hi, Is there a library for RGBmatrix, the color LED matrix sold by Adafruit and a few others? Adafruit has the library but it only works on UNO and Mega boards. I have some applications running on Mega but would like to move to the STM32F103 Blue Pill board for speed.

There are several implemnatations of libraries for addressable RGB leds.
I did one using SPI DMA and there is also a bit-banged one, which has been posted to the forum, and Rick Kimball has done an implementation using a different system to generate the pulse timing

However these are only for strips of LEDs, and do not have functions to draw as a matrix.

I bought a 1m strip of 144 LEDs a few weeks ago, with the intention of making a small matrix (12x12), but I have not had time to even cut the strip and mount it in a board etc
