SmartMatrixShield_with_Teensy_3_2.notes
Shield: https://docs.pixelmatix.com/SmartMatrix/shield-v1.html
Teensy: Version 3.2
Panel: HUB75E  P3-32S-HL1.2 (https://www.aliexpress.com/item/32931309452.html , https://www.ledycx.com/3mm-indoor-module.html )
Cannot find datasheet. Have requested it from supplier. Image of board here: https://i.imgur.com/zPoooRT.jpg
chip: FM6124
I've selected this panel type after setting width and heigh to 64:
const uint8_t kPanelType = SM_PANELTYPE_HUB75_64ROW_MOD32SCAN;
Panel sections:
A 64x16
B 64x16
C 64x16
D 64x16
If we characterize the data that is to be written to the sections as:
a, b, c, d
respectively, then the following behaviour is observed:
A(a)
A(b)
C(c)
C(d)
Physical sections B and C are not being accessed although the software is understanding that there are 64 rows in 4 chunks.
**Perhaps it is only 2 physical sections(32 row each) and it is configured for 4 (16 row each)
This line doesnt seem to make a difference.
#define USE_ADAFRUIT_GFX_LAYERS
MultiRowRefreshMapping.ino
#include <MatrixHardware_Teensy3_ShieldV1toV3.h>    // SmartMatrix Shield for Teensy 3 V1-V3
#if (SKETCH_MODE == MODE_MAP_REVERSE_ENGINEERING)
const uint16_t kMatrixWidth = 64;        // must be multiple of 8
const uint16_t kMatrixHeight = 64;
const uint8_t kPanelType = SM_PANELTYPE_HUB75_64ROW_MOD32SCAN;  
#endif
delay(25);  
Result: Pixel maps across left to right with 1 color pixel PER ROW and skips over the B and D sections. RED PURPLE YELLOW WHITE.
I just noticed that it is doing Aa Ab Cc Cd as described above. I wonder...

Following the instructions and setting:
#if (SKETCH_MODE == MODE_MAP_REVERSE_ENGINEERING)
const uint16_t kMatrixWidth = 1024; // must be multiple of 8 ***** (64*64)/4 = 1024
const uint16_t kMatrixHeight = 4;
/*either:*/ //const uint8_t kPanelType = SM_PANELTYPE_HUB75_4ROW_MOD2SCAN; // Use this to reverse engineer mapping for a MOD2 panel
/*or:*/ const uint8_t kPanelType = SM_PANELTYPE_HUB75_8ROW_MOD4SCAN; // Use this to reverse engineer mapping for a MOD4 panel
#endif

(vs say 1:3 which would make sense)
I now notice in MatrixPanelMaps.cpp there is NO map entry corresponding to:
SM_PANELTYPE_HUB75_64ROW_MOD32SCAN;
aka:
const PanelMappingEntry panelMap64x64Mod2[]
const PanelMappingEntry panelMap64x64Mod4[]
In any sketch changing kMatrixHeight to any other value than 64 results in blank screen.
Changing kMatrixWidth results in splitting the width of the display and mirroring things across both horizontal sections.
Changing width to 128 results in a fail to compile:"C:\\Program Files (x86)\\Arduino\\hardware\\teensy/../tools/arm/bin/arm-none-eabi-g++" -E -CC -x c++ -w -g -Wall -ffunction-sections -fdata-sections -nostdlib -fno-exceptions -fpermissive -felide-constructors -std=gnu++14 -Wno-error=narrowing -fno-rtti -mthumb -mcpu=cortex-m4 -fsingle-precision-constant -D__MK20DX256__ -DTEENSYDUINO=153 -DARDUINO=10813 -DARDUINO_TEENSY32 -DF_CPU=96000000 -DUSB_SERIAL -DLAYOUT_US_ENGLISH "-IC:\\Program Files (x86)\\Arduino\\hardware\\teensy\\avr\\cores\\teensy3" "-IC:\\Users\\Mawlxee\\Documents\\Arduino\\libraries\\SmartMatrix\\src" "-IC:\\Program Files (x86)\\Arduino\\hardware\\teensy\\avr\\libraries\\SPI" "C:\\Users\\Mawlxee\\AppData\\Local\\Temp\\arduino_build_485262\\sketch\\MultiRowRefreshMapping.ino.cpp" -o nul -DARDUINO_LIB_DISCOVERY_PHASE

I think you will struggle with a teensy 3.2, I had very limited success with my 3.2 doing any smartmatrix stuff with my 64x64 setup. Better with my Teensy 3.5 but really best to use the Teensy 4
