2022/03/22 Putting some P5 64x32 Azerone Panels To Good Use, a Big 128x192 Matrix

π 2022-03-22 01:01 in Arduino

Azerone was nice enough to send me some returned RGBPanels, including a bunch of P5 ones, so I started making a matrix with them:

And by the time I was almost done, I got 4 more, so that was enough for 192x128 with 12 panels. That happened to be the exact resolution of my LED outfit, although that one was 128x192. For wiring reasons and optimizing refresh speed with 3 parallel channels, I wired the array the wrong way display wise, but the best way hardware-wise:

Thankfully rpi-rgb-panel has a mode to flip, mirror and rotate the output, so it was easy to get back a 128x192 display, and run th exact same code that my outfit. This nicely allowed me to see the same thing between P2 and P5 pixels:

I now have 3 frames, fun :)
