Greetings, First, check wiring, twice. Then, change in --led-multiplexing option, from 1 to 14 (I think), ie, **--led-multiplexing=1, then --led-multiplexing=2, etc...** Also, if You're using a RPi 1, DON'T use...

Some of those panels are made putting together 2 or more standard (16x32, 16x16, 32x32, etc) panels, take a picture to the back of your panels, closest to try read...

I think a new pixel mapping is needed... at this time, this panel is not compatible with this library...

Greetings, You forgotten to use in your command these: --led-rows= : Panel rows. Typically 8, 16, 32 or 64. (Default: 32). --led-cols= : Panel columns. Typically 32 or 64. (Default:...

> @davemaster thanks. i used all possible combination of `--led-multiplexing` and `--led-row-addr-type`. also i used `rows` and `cols` options. > > i not wrote that in issue but i test...

Had You tried this code? Go ahead...

greetings Apparently you miss some clables pin location, check the RGBR1G1B1 cables again... one is in miss-order Best regards El vie., 23 oct. 2020 a las 11:04, Dominic Buchstaller (<...

Greetings, Could You share the command are You using? Also an Image of your rgb panel output PD- First thing I always do, check connection, check correct mapping for that...

try this: demo -D0 --led-rows=32 --led-cols=32 --led-chain=2 --led-multiplexing=1 (then 2, 3, .... etc), and picture best regards PD. What RPi are You using?
