64 x 64 Matrix Address Pins Problem

[sjpiper145]

I love the Expressive Pixels app and what your team has built with the interface. My 64 x 64 LED matrix purchased from Adafruit isn't displaying Express pixels very well as 5 Address Pin Matrixes haven't been included as yet. See picture here: https://imgur.com/a/yCVBIzJ

This problem has been fixed in the code for the Animated GIF Player using the Protomatter Library with NUM_ADDR_PINS. I've tried to integrate the code into the Arduino config for Expresive Pixels but I'm not having any luck.

#if defined(DISPLAY_MATRIX64x32)
uint8_t rgbPins[] = {7, 8, 9, 10, 11, 12};
uint8_t addrPins[] = {17, 18, 19, 20, 21}; // 16/32/64 pixels tall
uint8_t clockPin = 14;
uint8_t latchPin = 15;
uint8_t oePin = 16;
#if DISPLAYARRAY_HEIGHT == 16
#define NUM_ADDR_PINS 3
#elif DISPLAYARRAY_HEIGHT == 32
#define NUM_ADDR_PINS 4
#elif DISPLAYARRAY_HEIGHT == 64
#define NUM_ADDR_PINS 5
#elif DISPLAYARRAY_HEIGHT == 128
#define NUM_ADDR_PINS 5
#endif

Adafruit_Protomatter matrix(DISPLAYARRAY_WIDTH, 6, 1, rgbPins, NUM_ADDR_PINS, addrPins, clockPin, latchPin, oePin, true);

Any help with this would be deeply appreciated.

Cheers, Steph

I dont know if you still check this or have already solved it. I would try the following

• Check to make sure each of the matrixes (or the joined connector) Have 5v @ 4amps
• Did you solder the GPIO connector for the 64x64 Matrices?
