RGB LED Matrix & HAT - Impromptu Restart

by mozart27 on Sun May 02, 2021 2:37 pm

Hi,

I'm trying to run the demos on my RGB LED 64x64 matrix (PID: 3649) with the Adafruit RGB Matrix HAT + RTC for Raspberry Pi - Mini Kit (PID: 2345).

I've soldered the pad to accommodate the 64x64 matrix with this HAT.

I've downloaded and installed the demo app using these steps:

Code: Select all | TOGGLE FULL SIZE
curl https://raw.githubusercontent.com/adafruit/Raspberry-Pi-Installer-Scripts/master/rgb-matrix.sh >rgb-matrix.sh
sudo bash rgb-matrix.sh


Whenever I run the demo
Code: Select all | TOGGLE FULL SIZE
sudo ./demo -D0 --led-rows=32 --led-cols=1
the pi displays the following text and restarts.

Any thoughts on what I might be doing wrong?

Thanks in advance - jb

You didn't post the output.

What's happening on the matrix when it restarts?

How are you powering everything?

For power, I have the normal 5V microUSB plugged into the pi3 and another 5V 3A plugged into the HAT.

The output from the command is:

Code: Select all | TOGGLE FULL SIZE
pi@raspberrypi:~/src/rpi-rgb-led-matrix/examples-api-use $ sudo ./demo -D0 --led-rows=32 --led-cols=16
Size: 16x32. Hardware gpio mapping: adafruit-hat
Press <CTRL-C> to exit and reset LEDs

Huh. So no information about what causes the restart.

Yeah exactly. Nothing I can detect. Could under-voltage cause a spontaneous restart?
