2 years ago I use another version board (https://www.electrodragon.com/product/rgb-matrix-panel-drive-board-for-raspberry-pi-v2/), just to connect P4 with e_buf, it works for 64x64 panel, QiangLong P3 with icn2013ep chip embedded.

2 years ago Hello @xuniuer, can you please help me in setting up raspberry pi4 with the board that you have used(https://www.electrodragon.com/product/rgb-matrix-panel-drive-board-for-raspberry-pi-v2/). I bought the same one and connected to 32x32 led panels chained into 4 and paralleled to 3

2 years ago @xuniuer Please find the below additional details, I followed the README files of GitHub - hzeller/rpi-rgb-led-matrix: Controlling up to three chains of 64x64, 32x32, 16x32 or similar RGB LED displays using Raspberry Pi GPIO 1 and wired the things, I can able to see the unclear text/image while trying to run following commands " sudo python image-scroller.py --led-cols=64 --led-rows=32 --led-chain=2". Kindly help me to identify the issue and fix it.

However, here are some suggestions.
demo firstly to check necessary parameters or configurations, then use python to go ahead;multiplexing is the most important parameter to config panels, especially, when your panels could not run out of box;
panel type: P2.5 FM6127 64 * 64 bonnet: https://www.electrodragon.com/product/rgb-matrix-panel-drive-board-raspberry-pi/
First of all, I would also like to thank you for all the work and the much help you have given me. I never thought I would get this far, but it looks like a lot of learning and experimentation has paid off. My first problem was that there were blank lines left on the 64 * 64 display (16y16n16y16n) as here in the video:
https://www.youtube.com/watch?v=Y95ItZfQivA
But by switching this switch, the problem was resolved:
In fact, everything went well and goes well since then (demo D4, D7, text-scroller, etc.) if I drive a 6 64 64 panel on the P1 connector, but if I want to play video with the video-viewer , it's all a big flicker, whatever setting I'm running. I guess the problem here may be that I drive more than 24k LEDs on a single strand. I read that on a thread approx. The limit is 10k if you want to achieve a normal resolution and refresh rate.
In case I divide this by putting three panels on P1 and three panels on P2, only P1 will display image, not P2. The same is true if I put 2-2 panels on 3 channels, only P1 works P2 and P3 does not. If I put the line on P2, all I get is a blue light on the 64 64 display at 64 32 pixels.
I run the following command when I get relatively normal operation:

sudo ./demo -D10 --led-rows = 64 --led-cols = 64 --led-chain = 6 --led-parallel = 1 --led-panel-type = FM6127 --led-slowdown-gpio = 5 I am still modifying these values, but the same error: --led-chain = 6 --led-parallel = 1 --led-chain = 3 --led-parallel = 2 --led-chain = 2 --led-parallel = 3
I also ran this to see more examples:
sudo ./text-scroller -f ../fonts/texgyre-27.bdf -B0,0,255 -O0,0,100 -C255,0,0 --led-chain = 4 "Hello ♥" --led-rows = 64 --led-cols = 64 --led-chain = 6 --led-panel-type = FM6127 --led-slowdown-gpio = 5 --led-brightness = 20 -y10
I was sent a bit of a strange bonnet by Electrodragon, as I saw in several pictures that there are 6 jumper options to connect the lines, but I have 8 needles. Maybe I don't tie them in well? I also ordered two bonnets, both have the same problem.
I tried these connections, but none of them are good:
Thank you for your concern.
