Outdoor Matrix, Segmented output issue #1592

Open ValentinLaulund opened 1 year ago

ValentinLaulund commented 1 year ago

Hi all

The older outdoor matrix module we use, works great but has been discontinued, so I am trying to find a new P3 outdoor module.

The new I have found so far has these 2x4 segments split issue, it also look like the input is downscaled or duplicated, see image below (same hardware setup)

newOutdoor

I have tried, all combinations of the, --led-multiplexing. --led-row-addr-type --led-panel-typ Also swapped around the .a .b .c .d .e, it just changes the colors ... Surprise! ;)

My command string have been something like: sudo ./demo -D0 --led-rows=64 --led-cols=64 --led-multiplexing=1 --led-gpio-mapping="adafruit-hat-pwm"

I hope one of you guys have inputs for what I can try out, or tips on where to acquire an Outdoor (Brightness >= 5000 cd/m2) P3 64x64 RGB LED Matrix (192x192) that works with an Raspberry PI and the rpi-rgb-led-matrix library.

did you try --led-multiplexing=0

Yeah I tried all of the 18 options ;(

Using--led-multiplexing=0 it almost like the "images" overlaps. With the--led-multiplexing=1 (stripe) it looks better, but are still split up in a 2x4 grid.
