I am building a MIDI-Controller with RGB LEDs and would like to use the SmartMatrix library.
Is it possible to control RGB matrices with different sizes?
My matrix is 20x20 on a custom PCB, the interface is the same as the normal matrices.
Sorry if this is a stupid question, I am new to SmartMatrix.
Hi Moritz, what type of RGB LEDs are you using? I’m guessing WS2812s. SmartMatrix is designed to support multiplexed LED matrix displays, these have driver chips on the back of the board, not within the LEDs themselves.
Take a look at FastLED, they have a great library for driving ws2812s and other integrated LEDs and a great community too.
no I am not using WS2812, they are nice, but to big and power hungry for my project.
I know the way of driving matrices and my PCB will be designed to be compatible with them.
My question is: Can I modify the code to drive a Matrix with other dimensions?
I am using two MBI5026 (32 outputs, 20 used)
The best way to scan the matrix would be 1/10th scanning, is this possible? (maybe with 3 demultiplexers)
