Greetings! I’ve recently switched from 32x32 led matrix panels to a 64x64 matrix panel. I’ve been working around with settings but the closest I can get it to work is the image above. There are these black bands that don’t turn on. It’s not the LED multiplexing because that just jumbles the image more while keeping the black bands…
Any ideas on what I’m missing or what to try? Thanks very much for the help.
that worked! I put some female headers on the board so I can select between the pin 4 and pin 8
version with dupont jumpers. My display was of the pin 8 variety.
Hmmm… So strange… I still can’t get it working… I soldered header pins so I can test different configurations but the most I can do is reverse the part that’s on with the black stripes (so now the black strip area is turning ON). I can’t get the whole display to show at the same time… Is there anything that needs to be done with the code also?
The code does not care where the E pin is routed, it sends it to the same GPIO and the electrodragon board is responsible for sending that GPIO signal to the correct pin on the RGBPanel (via the jumper we discussed)
Hi @marcmerlin, I’m seeing the same issue. I’ve checked the spec of the panel I’m using and it’s 4=GND, 8=E. I’ve jumpered the board (Electrodragon matrix V2) accordingly but still have the black band. Removing the 4->GND doesn’t seem to have any effect and removing the 8->E moves the image down a few rows. Any ideas what else I can try? Any help would be much appreciated, thanks.
