Re 2d matrix art, without using smartmatrix what approach/suggestions would folks recommend for 2d matrix of arbitrary size (I have 16x27 matrix controlled by teensy 3.2) e.g to facilitate animating a gif or displaying custom art patterns?
The AnimatedGIFs sketch isn’t 100% tied to SmartMatrix. You can take out all the SmartMatrix-related code in one file and replace it with code that sets pixels in a FastLED buffer or something else instead. My goal is to turn AnimatedGIFs into a Arduino Library that’s completely independent of SmartMatrix so more people can use it, but I haven’t quite gotten there yet.
Just remove all the SmartMatrix code in AnimatedGIFs.ino, replace with code to setup FastLED in setup(), and code to draw to the buffers and update LEDs in the callback() functions.
I just managed to get a teensy 3.2 working with FastLED, LEDMatrix, and Octo. That allows 2 d art over a really big panel size via 8 pin parallel output. if your panel is less thatn 256 pixels, then you can use almost any processor and skip the octo part. (i.e. just use fastled and LEDmatrix) on a single pin.
@Louis_Beaudoin that would be very cool, thank you
