ICND2055 not working #1342

Open fecri opened 2 years ago

fecri commented 2 years ago

Hello everyone,

I have a problem with Rapsberry Pi and a p2.5 panel 128*64 (e-line). The chipsets are ICND2055. The screen is not light up.

Can you help me to implement a new logic for this kind of chipset ?

The datasheet: ICND2055_datasheet_EN_2021_V1.8b.pdf

Thank you.

How did you connect it ? With or without level shifters or do you use one of the existing adapters ?

Hi, I use active-3 adapter from https://www.electrodragon.com/product/rgb-matrix-panel-drive-board-raspberry-pi/.

Thank you

Ok, so what did you try to make it work, what command line options are you using and were testing ?

fecri commented 2 years ago

I tried commands like above:

./led-image-viewer --led-cols=128 --led-rows=64 --led-row-addr-type=4 --led-slowdown-gpio=3 --led-panel-type=FM6126A -f ...

./led-image-viewer --led-cols=128 --led-rows=64 --led-row-addr-type=4 -f ...

The datasheet of the ICND2055 is confusing and one would probably have to probe directly with an oscilloscope to better understand how it is integrated in the led matrix panel. The interesting part is that it seems to have a very long shift register for all rows ? I don't have a ICND2055 panel to test, so you'd need to do that work and write up who it works there and ideally send a pull request to support.

I will work on this. thank for all :)

Я буду работать над этим. Спасибо за все :)

Hi! Have you managed to connect such a matrix? I have the same problem, I will be glad of any hint

fecri commented 2 years ago

Hi sorry for the late response. I don't have solution for this issue.

Can I ship you a panel ? I have 10 panels, you can keep it. I will pay shipment fees.
