128x32 Matrix

Open arconkli opened this issue 3 years ago • 3 comments

Hey, I'm trying to get my 128x32 matrix setup and when I use the flags: --led-parallel=1 --led-chain=2 --led-cols=64 --led-rows=32 --led-show-refresh --led-limit-refresh=0 --led-pwm-lsb-nanoseconds=175 nothing shows up, but when I change the "--led-parallel=1" to "--led-parallel=2" and "--led-rows=32" to "--led-rows=16" I get something that looks like this IMG_6530 This --led-parallel=2 --led-chain=2 --led-cols=64 --led-rows=32 --led-show-refresh --led-limit-refresh=0 --led-pwm-lsb-nanoseconds=175 also works and fills in all the pixels but naturally only shows the bottom half because it thinks it is 128x64. It seems like I could just change "--led-parallel=2" to "--led-parallel=1" and it should work. But when I do that the screen just stays blank.

It seems to only show an output when the led-parallel is 1>.

This is all I've got to somewhat work with the "runtext" however it doesn't work with the rotating square as it puts it to the very left side in the "middle" of the 256x32. sudo ./demo -D1 --led-parallel=2 --led-chain=1 --led-cols=128 --led-pixel-mapper=V-mapper --led-show-refresh --led-limit-refresh=0 --led-no-hardware-pulse --led-row-addr-type=0 --led-slowdown-gpio=3 runtext16.ppm

Greetings If You don't know what type of RGB PANEL have, try with different values of --led-multiplexing=XXX

good luck
