It seems like the Pixels are shifted,

anyone know the answer

Could you send a picture of the back of your LED Panel?

Greetings,

You wanna be helped? First, take many pictures to your panel, specially to: HUB-75 LED INPUT, code of the RGB PANEL.
Second, use the command :

Command used on the Raspberry PI 4
"sudo ./demo -D 7 --led-rows=64 --led-cols=64 --led-gpio-mapping=adafruit-hat --led-slowdown-gpio=5"

and record a video of the result.

Best regards

Hello @davemaster.
thank you for your reply!
here are some picture of the back of my matrix:

as well as a video with the command you provided:

Hi Glappa,
Thanks for all of the pictures and videos, it looks like it might be an issue with how your E Line is set up, I was running a similar setup, slightly different board but same Hub 75 configuration. Could you try and solder a jumper from Pin 4 (OE) to Pin 18 on the RPI Bonnet board and run it again? If you want to double check before soldering it you should be able to steadily hold a wire on the two contacts and it should get reflected instantly on the board.

Hello @Nam0,
Did you mean it like this?

Gotcha, and just to double check you have the E and 8 pins on the underside of the bonnet board bridged correct?

this is the backside of the Bonnet:

Ah I see you don't have the E line pin soldered up, you will need to go thru and bridge the connector from E to 8 for these two pins

i bridged this part of the Bonnet (it is the backsite)
