RGB LED MATRIX- 5mm pitch wont turn on

by clearwhite09 on Tue Jun 23, 2020 5:43 pm

I am working on a NHL-LED-scoreboard project (https://github.com/riffnshred/nhl-led-scoreboard)
and the 64X32 RGB LED Matrix -5mm pitch isn't working/lighting up

Hardware I am using:

Raspberry Pi Zero WH
ADAFRUIT RGB Matrix Bonnet for Raspberry Pi
RGB LED MATRIX 5mm pitch
16Gb Sd Card
5v 4A power suppy

I feel I should say this is my first project with the PI, but I have wired and seated the bonnet to the pi and used mounts/standoffs to help support.
the Pi and Bonnet have the green Led lit on the board.

I am using raspberry pi buster lite, I have also set up a SSH connection to the Pi.
following that I have followed the steps "headless" and installed the software per what i read/understood.

I still haven't seen any light or indication that this display works, I would like some help either trouble shooting or best tips to know that the display isn't effected from a hardware stand point, and maybe its a simple software setup/install?

Since you have the PWM jumper installed. Make sure you invoke the program using the PWM flag --led-gpio-mapping=adafruit-hat-pwm
