Are you using the image version or are you installing manually following the instructions in the wiki? FYI, the pinouts on the panels can be the same, but the chips on them might be different, which might be the cause. |

that makes sense... I used the image, which otherwise was flawless btw. Kudos. I did try the upgrade through ssh to .12 (i think). i'm at best getting blotches of color... Chips seem to say RUL6024 |

If you see boobs of colors or led flashing, make sure the Bonnets don't touch the raspberry pi underneath it. Also, make sure all cables are properly inserted in their socket. I don't recognize the chip model but if you look at the rpi-rgb-led-matrix repository, you might find some help. that's the driver we are using to run the display. |

Did you use the indoor or outdoor matrices? |

I bought indoor panel since I was not going to put these outdoor and was getting them cheaper that outdoor panels. Here is a picture of mine, 4 panels.

It does cut off some of the team logos as the code it not written for 4 panels. |

This your code or utilizing the diy nhl scoreboard stuff for rpi? Looks great! |

Sorry for the lateness of my reply.... Here is my command line that I ended up with, I ran mine using Supervisor. command=sudo python3 src/main.py --led-gpio-mapping=adafruit-hat-pwm --led-brightness=60 --led-slowdown-gpio=2 --led-chain=4 --led-parallel=1 --led-pixel-mapper=U-mapper --led-cols=64 --led-rows=32 |

Thank you. Will give it a try when I get back from my son's hockey
tournament. Seems like I did add this to mine to make it work,
(--led-pixel-mapper=U-mapper), well at least I am hopeful.

using Raspi 4's, matrix(s) from Aliexpress (p5 2121-16s-6430 B0 / 2PS610c) and adafruit bonnets, i get zilch. i have 4 panels total, and 2 bonnets, have tried both bonnets on various boards, and i cannot get ANYTHING for output. I've compared pinout on my boards to the adafruit 64x32 p5 and they are identical. I've verified voltage out from bonnet is 4.8v. Have tried with pi powered seperatly as well. (does throw low power warning if not powered seperatly). have even tried numerous power and data cabels... Ideas where i can start here?
