Mapping Assistance 32x16 P10

Hi renda71.
Yes it works
My patch is a patch !
I modify original code using #define

first in file MatrixEsp32Hub75Calc_Impl.h line 627

#define ERIC_H45_PATCH 1
#if (ERIC_H45_PATCH == 1)
#pragma message "ERIC_H45_PATCH == 1"
					if (gpioRowAddress ==-1){
						v|= ( (BIT_A) | ( BIT_B) | ( BIT_C) | ( BIT_D) | ( BIT_E) );
					}
					else {
						switch (gpioRowAddress % 4){
							case 0 : v|= ( (!BIT_A) | ( BIT_B) | ( BIT_C) | ( BIT_D)); break;	
							case 1 : v|= ( ( BIT_A) | (!BIT_B) | ( BIT_C) | ( BIT_D)); break;
							case 2 : v|= ( ( BIT_A) | ( BIT_B) | (!BIT_C) | ( BIT_D)); break;
							case 3 : v|= ( ( BIT_A) | ( BIT_B) | ( BIT_C) | (!BIT_D)); break;
						}
					}
//		Serial.print("PATCH: gpioRowAddress=");Serial.print(gpioRowAddress);Serial.print(" / ");Serial.print(gpioRowAddress,BIN);Serial.print("  V= ");Serial.println(v,BIN); 
#else                    
					if (gpioRowAddress & 0x01) v|=BIT_A;
                    if (gpioRowAddress & 0x02) v|=BIT_B;
                    if (gpioRowAddress & 0x04) v|=BIT_C;
                    if (gpioRowAddress & 0x08) v|=BIT_D;
                    if (gpioRowAddress & 0x10) v|=BIT_E;
#endif

then line 946 :slight_smile:

#if (ERIC_H45_PATCH == 1)
#pragma message "ERIC_H45_PATCH == 1"
					if (gpioRowAddress ==-1){
						v|= ( (BIT_A) | ( BIT_B) | ( BIT_C) | ( BIT_D) | ( BIT_E) );
					}
					else {
						switch (gpioRowAddress % 4){
							case 0 : v|= ( (!BIT_A) | ( BIT_B) | ( BIT_C) | ( BIT_D)); break;	
							case 1 : v|= ( ( BIT_A) | (!BIT_B) | ( BIT_C) | ( BIT_D)); break;
							case 2 : v|= ( ( BIT_A) | ( BIT_B) | (!BIT_C) | ( BIT_D)); break;
							case 3 : v|= ( ( BIT_A) | ( BIT_B) | ( BIT_C) | (!BIT_D)); break;
						}
					}
//		Serial.print("PATCH: gpioRowAddress=");Serial.print(gpioRowAddress);Serial.print(" / ");Serial.print(gpioRowAddress,BIN);Serial.print("  V= ");Serial.println(v,BIN); 
#else                    
					if (gpioRowAddress & 0x01) v|=BIT_A;
                    if (gpioRowAddress & 0x02) v|=BIT_B;
                    if (gpioRowAddress & 0x04) v|=BIT_C;
                    if (gpioRowAddress & 0x08) v|=BIT_D;
                    if (gpioRowAddress & 0x10) v|=BIT_E;
#endif

That’s all for this file.

Now maping:
in MatrixCommonHub75.h
I define a new variant of SM_PANELTYPE_HUB75_16ROW_32COL_MOD4SCAN_V3 :, SMARTMATRIX_HUB75_16ROW_32COL_MOD4SCAN_V3:

#define SM_PANELTYPE_HUB75_16ROW_32COL_MOD4SCAN_V4  13

 #define SMARTMATRIX_HUB75_16ROW_32COL_MOD4SCAN_V4   SM_PANELTYPE_HUB75_16ROW_32COL_MOD4SCAN_V4

and duplicate it in all the file.

in MatrixPanelMaps.cpp the new mapping:

const PanelMappingEntry panelMap32x16Mod4V4[] =
{
    {0, 7, -8},
    {0, 23, -8},
    {0, 39, -8},
    {0, 55, -8},
	{4, 8,   8},
    {4, 24,  8},
    {4, 40,  8},
    {4, 56,  8}, 
    {0, 0, 0}   // last entry is all zeros
};

and at the end of the file in the switch (paneltype) add :slight_smile:

    case SMARTMATRIX_HUB75_16ROW_32COL_MOD4SCAN_V4:
        return panelMap32x16Mod4V4;

it will be nice to replace #define with a runtime option of course.

hope this help.

Best regards
Eric
