Hi Louis! Thank you so much for your quick reply!
Both panels have been tested separately and run fine, they run the demo sketches and my own gifs perfectly. Also I should add I have tested both chained to panels of the same size (ie the 32x32 to another 32x32 and the 64x32 to another 64x32) and they also have no issues, no problems with playback or mapping.
Both panels are connected to the same power supply, which is 5v 10a which I thought should be plenty of current but I will try a higher current and separate power supplies as well now.
Current config (very simple)
#define USE_ADAFRUIT_GFX_LAYERS
// uncomment one line to select your MatrixHardware configuration - configuration header needs to be included before <SmartMatrix.h>
//#include <MatrixHardware_Teensy3_ShieldV4.h> // SmartLED Shield for Teensy 3 (V4)
#include <MatrixHardware_Teensy4_ShieldV5.h> // SmartLED Shield for Teensy 4 (V5)
//#include <MatrixHardware_Teensy3_ShieldV1toV3.h> // SmartMatrix Shield for Teensy 3 V1-V3
//#include <MatrixHardware_Teensy4_ShieldV4Adapter.h> // Teensy 4 Adapter attached to SmartLED Shield for Teensy 3 (V4)
//#include <MatrixHardware_ESP32_V0.h> // This file contains multiple ESP32 hardware configurations, edit the file to define GPIOPINOUT (or add #define GPIOPINOUT with a hardcoded number before this #include)
//#include “MatrixHardware_Custom.h” // Copy an existing MatrixHardware file to your Sketch directory, rename, customize, and you can include it like this
#include <SmartMatrix.h>
#define COLOR_DEPTH 24 // Choose the color depth used for storing pixels in the layers: 24 or 48 (24 is good for most sketches - If the sketch uses type rgb24
directly, COLOR_DEPTH must be 24)
const uint16_t kMatrixWidth = 96; // Set to the width of your display, must be a multiple of 8
const uint16_t kMatrixHeight = 32; // Set to the height of your display
const uint8_t kRefreshDepth = 36; // Tradeoff of color quality vs refresh rate, max brightness, and RAM usage. 36 is typically good, drop down to 24 if you need to. On Teensy, multiples of 3, up to 48: 3, 6, 9, 12, 15, 18, 21, 24, 27, 30, 33, 36, 39, 42, 45, 48. On ESP32: 24, 36, 48
const uint8_t kDmaBufferRows = 4; // known working: 2-4, use 2 to save RAM, more to keep from dropping frames and automatically lowering refresh rate. (This isn’t used on ESP32, leave as default)
const uint8_t kPanelType = SM_PANELTYPE_HUB75_32ROW_MOD16SCAN; // Choose the configuration that matches your panels. See more details in MatrixCommonHub75.h and the docs: Home · pixelmatix/SmartMatrix Wiki · GitHub
