RGB 32 x64 Matrix not Working using arduino metro.

by clv001 on Wed Nov 25, 2020 8:43 am

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.

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.

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.

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.

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 | TOGGLE FULL SIZE

// Demonstrates the drawing abilities of the RGBmatrixPanel library.
// For 32x64 RGB LED matrix.

// WILL NOT FIT on ARDUINO UNO -- requires a Mega, M0 or M4 board

#include <RGBmatrixPanel.h>

// Most of the signal pins are configurable, but the CLK pin has some
// 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
// on the same PORT as the RGB data pins (D2-D7)...
// Pin 8 works on the Adafruit Metro M0 or Arduino Zero,
// Pin A4 works on the Adafruit Metro M4 (if using the Adafruit RGB
// Matrix Shield, cut trace between CLK pads and run a wire to A4).

#define CLK  8   // USE THIS ON ADAFRUIT METRO M0, etc.
//#define CLK A4 // USE THIS ON METRO M4 (not M0)

OK. We can try replacing the panel. Please contact support@adafruit.com with a link to this thread and we can get one out to you.

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.

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.
