@hzeller Hi master, I am using a RGB Matrix + RTC board and it gives me the mentioned problems how can I solve them.

jonasradke commented 2 years ago

What is the command that you use to run this?

Bano310 commented 2 years ago

¿Cuál es el comando que usas para ejecutar esto?

@hzeller sudo ./text-example -f ../fonts/cu12.bdf --led-chain=8 --led-slowdown-gpio=5

jonasradke commented 2 years ago

So led slowdown only accepts range from 0-4. You should try to use the flags —led-cols and —led-rows to set the amount of pixels in a single matrix. Also it does not look like you have 8 panels chained together but maybe they are just not in the photo.

In general @Bano310 it would be helpful if you give more information about your set-up: how many panels do you have, which are the sizes of each panel, how have you wired them up (in one chain, in parallel); what is the RTC board you are talking about (link).

As @jonasradke said, set the --led-cols and --led-cols to the size of a single panel, then use --led-chain with the number of panels you have chained together.

The artifact you see looks like, you need to play around with --led-multiplexing to see if this matches your panel.

(--led-slowdown-gpio suggests 0..4, but it actually allows for up to 5 but it is a hidden feature as this usually should not be needed).
