Panel HUB75E 128x64 and Raspberry Pi Zero W error, always big bars green and blue. #1227

Hello, first of all thank you for the possibility that I am given to share my problem.

I have a Rasberri Pi Zero W connected directly to a 64x128 panel and HUB-75E connector using the web schematic https://github.com/hzeller/rpi-rgb-led-matrix/blob/master/wiring.md and when I run the demo I get a half green and half blue screen but no image (image capture). I want to try not to use any Adafruit HAT because I am only going to show only texts and make it as simple as possible to adapt it behind the screen

I have checked the wiring several times and everything is correct, following the pinout of :) 😄

I try too: sudo ./demo -D 0 --led-rows=64 --led-cols=128 --led-gpio-mapping=regular-pi1

and I don't know what else to review ... could you guide me or if someone knows what it could be? Thanks a lot!

I think you need to leave away the "--led-gpio-mapping=regular-pi1" as it is for a Pi One and your pix shows a recent Pi Zero (it has wifi on board)

Hello friend, first of all thank you very much for having answered... after continuing testing I decided to reinstall everything completely, and re-download the library once downloaded I launch the command:

make -C examples-api-use

and it performs all the steps correctly without receiving an error, but when I execute the command now I get another different image but just as wrong:

sudo ./demo -D0 --led-rows=64 --led-cols=128

o

sudo ./demo -D0 --led-rows=64 --led-cols=128 --led-row-addr-type=1

and some more combinations of different parameters but still the same. thumbnail_image

Many thanks 👍
