Panel P2.5 128x64 Hub75 ABC no display

1

Hello everyone,

I have four 128x64 P2.5 LED panels. I installed the rpi-rgb-led-matrix library. I tried numerous commands, but without success. I try with a pi 3 and pi 4.

My Hardware

A Raspberry Pi 4 with Pi OS Lite 64-bit.

RGB LED matrix panel driver board for Pi (ElectroDragon), model MPC1073

Power supply: Mean Well 5V LRS-350

Panels: 128x64 px

Driver IC: TC7958A

Model: P2.5 128x64 px 320x160mm

Connection: HUB75 type ABC

1/8 Scan

The problem is that I can’t display an image or text on the panel.

Command: sudo ~/rpi-rgb-led-matrix/utils/led-image-viewer --led-cols=128 --led-rows=64 --led-chain=1 --led-parallel=1 --led-gpio-mapping=regular --led-slowdown-gpio=4 --led-no-hardware-pulse --led-panel-type=FM6126A --led-row-addr-type=5 -f ~/box-1.png

for the test, i use one panel

It doesn’t show anything

According to your photos, the panel has a 64 scans (why did you decided that it 1/8 ?) and has a driver SM16380. This is a new PWM type driver that not supported by the library.
There is no workaround for this issue yet.

Hello,

thanks for the reply,

Is there a way to make them work with a raspberry pi ?

Only if you make a firmware yourself.

to be clear, PWM panels are entirely different in how they work compared to older row scan panels, which are the ones supported by this lib.

PWM panels are better, but they need a new library which has not been written and someone like you have to write it, or find and pay a competent software engineer to write and open source the driver

Hello,
Okay, I’ll wait for that.

If everyone waits, it will never happen.

to be clear, there are no plans of anyone writing this for free.

If you want it/need it, I recommend you find someone to contract to write and contribute it.
