64x64 LED panel 1/16 scan requires new multiplex-mappers #1640
Comments
Hi, I'm in the same situation, is there anyone who could guide us in creating a new mapping? Thx a lot. Romain. |
i got a 1/16 scan 64x64 from here this works so far: |
Greetings, Try to start analyzing your panel, using an step, by step pixel drawing, one by one so your see on your panel the pattern. I remember one code in Arduino, x - column, y - row, using two for loop.... with a delay, and voila, then, put your new pattern into your multiplex-mappers.cc; if success, share here please. here in this link from this repository, a way to understand better what you need to do... I'm out of time right now. |
better that the link you get your panel, pictures of it, of its ICs, its hub75, any code or serial... Thanks in advance PD. Also share the command You used. For example, for the adafruit panels I have, I use: ./demo --led-rows=32 --led-cols=32 -D 0 (no --led-multiplexing, this panels are by default compatible) |
here, my 64x64 32S P3 Screen, I had to mod the Electrodragon rpi rgb adapter, FIRST, look where in your panel HUB75 is the E pin... in my case, was in PIN 8. ALL details of my mod, here in my video |
Hi All, Turns out the fix for the LED module was the --led-row-addr-type=3 Flag. Once I added this flag I was able to use Python and send images and text to the board. I've since created a 64 * 128 python script that generates QR Codes and Images based upon 4 GPIO inputs. It's a demo I'm creating for car park access. The demo can also output network / time settings. Have a look at the Video (compressed) 128_64_demo.mp4Regards, Martin |
Hi,
I recently purchased a P2.5 64x64 outdoor LED Panel https://www.aliexpress.com/item/1005005908894934.html
and the led-multiplexing doesn't seem to work for the 1/16 Scan.
I have an indoor P3 64x64 1/32 Scan panel that works fine.
How can I implement a 19th custom multiplex-mappers.cc file to the rpi-rgb-led-matrix?
Thanks
