This group provides volunteer based support for your projects based on GitHub - hzeller/rpi-rgb-led-matrix: Controlling up to three chains of 64x64, 32x32, 16x32 or similar RGB LED displays using Raspberry Pi GPIO . If you can help out, please do, others will thank you 
Please do not post “my panel doesn’t work, please help”.
- which panel? how many address lines? picture of the back connector with labels (if any)?
- did you read the entire README and tried the different address line and multiplexing options?
- show the command lines that you used and if relevant, photos of what output you get
- more generally, we won’t play 20 questions with you to ask information required to help you. Please do your best to provide that information upfront. More hints: How To Ask Questions The Smart Way
