I have just received an RGG 32 x64 Matrix LED with adafruit shield and arduino Metro M0 board. I have downloaded the libraries, RGB Matrix Panel and AdafruitBusIO, run the sample testshaps_32x64 program, bit LED RGB Matrix not running up, No circuit diagrams are available for troubleshooting the LED Matrix. How can I found out if the Matrix is faulty or not ?
I urgently need to use this matrix for demo purposes.
Thank you.

Re: RGB 32 x64 Matrix not Working using arduino metro.
Please find attached the photoes. There are no shorts between pins, The Metro M0 board is working because I used it with ADAfruit LCD.. I am not able to check the 64x32 RGB Matrix.
If you can send me a working test program will be great I try it out.
Thank you.

Re: RGB 32 x64 Matrix not Working using arduino metro.
I am including some more pictures. Matrix remains fully blank altough 5V is available on the Power terminal of the shield and power socket of matrix.

Re: RGB 32 x64 Matrix not Working using arduino metro.
I don't see any soldering issues. Double-check the connector orientation on the panel. The key on the connector should face out toward the edge of the matrix panel.

Re: RGB 32 x64 Matrix not Working using arduino metro.
The key is also in the correct orientation, inserted in the Input socket of matrix connector. I am using the following program but nothing works.
Code: Select all

#include <RGBmatrixPanel.h>

// special constraints. On 8-bit AVR boards it must be on PORTB...
// Pin 11 works on the Arduino Mega. On 32-bit SAMD boards it must be

// Pin 8 works on the Adafruit Metro M0 or Arduino Zero,
// Pin A4 works on the Adafruit Metro M4 (if using the Adafruit RGB

Re: RGB 32 x64 Matrix not Working using arduino metro.
OK. We can try replacing the panel. Please contact [email protected] with a link to this thread and we can get one out to you.

Re: RGB 32 x64 Matrix not Working using arduino metro.
You can always try these panels without powersupply, just with USB power first. Make sure you only light up a few pixels at a time. so you stay under 500mA. I managed to run Pac-Man from USB power at 20% brightness. That way you can ensure it is not a problem of conflicting power sources.

Re: RGB 32 x64 Matrix not Working using arduino metro.
clv001,
Did you ever get a replacement and if so did it fix the problem?
I am having the same problem with mine also. I checked the solder joints, connections. I am using the switching power supply 5v at 4 a. I checked the voltage leaving the shield going to the matrix with the matrix attached and it is reading 4.1 volts. I wonder if the voltage regulator on the metro M0 is defective and/or matrix is bad.
thanks for answering if a replacement corrected the situation.
