LED Matrix Power Issue?

[leatherman5150]

Hello,

Pretty new to microcontrollers & the Adafruit catalog, so be gentle... ha.

I followed your steps (great walkthrough by the way, very simple and straightforward for a newcomer like myself), and for some reason i am getting nothing from the LED matrix's. No initializing screen.. nada. I am curious if there is a power issue, i am using a raspberry pi 4B with the Adafruit Bonnet & the 4A power supply. Only difference between my setup and your is that i am using the 5mm pitch instead of the 4mm. Did you wire boards straight to the power supply? Or did you go through the bonnet? I read on Adafruit's website that they recommend the terminal style attachment to power the bigger boards. When i run the software on PowerShell, i can see the ESPN API being pinged.. so i assume the software is doing it's job. It is just getting lost in translation to the board.

Thanks again for putting all this together!!

Hey there, I have my displays wired to the Adafruit bonnet. If the display is showing nothing at all, it sounds to me like the rgb led matrix didn't initialize. That is a separate bit of code we need to get working in our project. Do the lights on the adafruit hat light up when the pi gets power? You aren't double powering the pi, powering the pi over usbc while the adafruit bonnet is attached and powered? You can re-run through this section - it won't hurt anything to try again : https://github.com/ChuckBuilds/LEDMatrix?tab=readme-ov-file#system-setup--installation

Good Morning Chuck,

I jumped back into this project last night, and ran through the system setup once again with no changes to the LED not responding. From a high level, here are the steps i am taking:

1. Image Raspberry Pi (Raspberry Pi 4 in my case)
2. Verify Wifi connection
3. Run through LED matrix system config
4. Remove sound module
5. Optimize performance
6. Edit config.json
7. Based on which features are being used (only sports in my case) verify config is enabled in config.json
8. Run the display (via sudo python3 display_controller.py)

Also - i forgot to mention.. i tried your test command (python test_odds_ticker.py for example) and the python file was not able to be found. Would you have an idea to why that would be?

Let me know if you have any ideas as i continue to troubleshoot.

Thanks again for putting all this together.

I'm so sorry, I missed this post. Have you got it working?
