Weird scan pattern

[DoomHammer]

Hi @board707 !

Here's some more details about the cursed panel with weird pattern.

It's 2 mux pins, 2 scan lines, and what you see uses #define DISPLAY_TYPE 2,32,16,2,1

define DISPLAY_TYPE 2,32,16,2,1

try this variants:

2,32,16,2,2 2,32,16,2,3 1,32,16,2,2 1,32,16,2,2

Do you want recording from there or just a plain "works/doesn't"?

[board707]

If any of them will run more than 2 pixels horizontally in a serie...

[DoomHammer]

With 1 mux line, the pixels get two levels of brightness (or something like that) after some time

2,32,16,2,2

2,32,16,2,3

1,32,16,2,2 (this was mentioned twice by you, on purpose?)

Disconnect the "B" line from the STM and connect B pin on the HUB to GND permanently. Than run the pattern 1,32,16,2,2 again. Will it run up to full panel width? The more long video could be useful

[DoomHammer]

Again I'm using a PCB here, so no way to change connections. Will try when I set up another board.

[board707]

Connecting B to the GND is not the main thing; when selecting one pin mux , the B pin should already have a low level. The main thing is: do the pixels go to the end of the panel?

[board707]

Hi, did you resolved the problem?

[DoomHammer]

Not yet, didn't have time to give it my proper attention since the last time :(

[board707]

Ok, If you will need my help, write.

Merry Christmas!
