QiangLi P6 48x24 working not correct

Open Rpsl opened this issue 1 year ago • 6 comments

Hello.

I have a QiangLi P6 Outdoor matrix, 48x24 diodes. I connected it according to the instructions in wiring.md, but it doesn't work properly.

The label on the matrix says it is ‘sm16208sj + rul5158c’, also on the matrix I see not typical HUB75 pins.

  • When I try to run with ./demo -D 4 --led-gpio-mapping=regular, every odd line lights up.
  • When I try to run with ./pixel-mover --led-gpio-mapping=regular, I see a couple of pixels with (0,0) and zero pixels with (0,1).

I don't understand if this is a wiring problem or a multiplexer problem. If it is a multiplexer problem, how can I determine the correct positioning?

Can anyone help me with this?

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: 32). --led-multiplexing : panel scan, test from 1 to 14 (i think)

@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 it.

what exactly you wrote?

./demo -D 4 --led-gpio-mapping=regular --led-cols=48 --led-rows=24 
   --led-multiplexing=0..18 # i try all options
   --led-row-addr-type=0..4 # i try all options

And, a PICTURE at least of the value of multiplexing that better works ?

Values of --led-multiplexing don't give any changes. At some multiplexing values every second line is filled in the matrix, at others it does not lighting matrix.

this is how it looks: IMG_4247

ps.

  • It's work only with --led-row-addr-type=0, with other options matrix not lighting.
  • I check it with matrix on another chip and my setup work correct.
  • I check it with several other matrix (QiangLi P6 sm16208sj + rul5158c) and that problem repeated.

just bought new panels with another chipset and they work perfect
