Chain 64x64 instead of 128x32? #1249

Open rgrech35 opened 3 years ago

Hello, I've been playing around wiht some other packages that use rpi-rgb-led-matrix (namely the NHL and MLB led scoreboard projects).

I have two adafruit 64x32 panels that i have chained together. When I use --led-rows=62 --led-cols=32 --led-chain=2, this seems to force a 128x32 mode rather than a 64x64 mode. I don't know if I'm using the wrong configuration opions or if rgbmatrix always views chaining as rectangular instead of square.

Any suggestions are appreciated thank you.

Hey! I've the same Problem. But i've using the go binding.

I cannot get this two panels work as on big 64x64. I've tried every combination of --led-cols, --led-rows, --led-chain and --led-pixel-mapper.

Due to inactivity on the go binding repo i thought i can try here to find some help?

I know this post is old but has anyone figured this out?

Try: --led-parallel=2 and use Active-3 HAT

I ordered 2 of the active-3 hats a couple hours ago. I currently have the adafruit bonnet and I have had zero luck getting 4 32by64 panels to do 64 by 128. I have tried doing the solder mod to both the number 8 pad and the number 16 pad still no help. I have also tried about every switch configuration possible and still no luck. Im going to solder pins to the adafruit board so that I can change back and forth from the 8 and 16 pad on the fly.

Try --led-pixel-mapper="V-mapper"
