Mapping settings for Matrix Portal

by chopomatic on Tue Jun 15, 2021 5:16 am

Hi all,

I'm trying to build the project laid out here:

https://www.mickmake.com/post/build-an-mqtt-based-rgb-led-panel-project/

The author is using the Adafruit RGB "bonnet" for the Pi, on a 64 x 64 matrix.

As you'll see when you look at the project, he's running a lot of the code inside a Docker container. I found the config.json file inside that container and edited it to properly reflect that I'm using a 64 x 32 panel, but I still just get distorted gibberish on the panel. I feel like the problem is in the settings contained in the panel definition section of the config.json file that's listed below. Can anyone tell me what settings I should be using for the Matrix Portal?

Code: Select all | TOGGLE FULL SIZE
   "panel":
   {
      "hardware_mapping":"adafruit-hat-pwm",
      "led_rgb_sequence":"RGB",
      "rows":32,
      "cols":64,
      "chain_length":1,
      "parallel":1,
      "brightness":100,
      "scan_mode":1,
      "show_refresh_rate":0


Huge TIA!
