Pxmatrix library not working fine for chained four 32 x 16 P10 RGB modules

[dileeppulluru]

Hi, Px matrix library is not working fine for chained P10 RGB modules. i have connected 4 p10 modules 0f 32X16 each . Modules in row = 2 modules in column =2 . Here is my code I have used ESP8266MOD

Anyone please assist me in this problem

/* code */

#include <PxMatrix.h>

// Pins for LED MATRIX

#ifdef ESP8266

#include <Ticker.h> Ticker display_ticker; #define P_LAT 16 #define P_A 5 #define P_B 4 #define P_C 15 #define P_D 12 #define P_E 0 #define P_OE 2

#endif

#define matrix_width 64 #define matrix_height 32 // This defines the 'on' time of the display is us. The larger this number, // the brighter the display. If too large the ESP will crash uint8_t display_draw_time=60; //30-70 is usually fine

PxMATRIX display(64,32,P_LAT, P_OE,P_A,P_B,P_C); //PxMATRIX display(64,32,P_LAT, P_OE,P_A,P_B,P_C,P_D); //PxMATRIX display(64,64,P_LAT, P_OE,P_A,P_B,P_C,P_D,P_E);

// Some standard colors uint16_t myRED = display.color565(255, 0, 0); uint16_t myGREEN = display.color565(0, 255, 0); uint16_t myBLUE = display.color565(0, 0, 255); uint16_t myWHITE = display.color565(255, 255, 255); uint16_t myYELLOW = display.color565(255, 255, 0); uint16_t myCYAN = display.color565(0, 255, 255); uint16_t myMAGENTA = display.color565(255, 0, 255); uint16_t myBLACK = display.color565(0, 0, 0);

uint16_t myCOLORS[8]={myRED,myGREEN,myBLUE,myWHITE,myYELLOW,myCYAN,myMAGENTA,myBLACK};

#ifdef ESP8266 // ISR for display refresh void display_updater() { display.display(display_draw_time); } #endif

void display_update_enable(bool is_enable) {

#ifdef ESP8266 if (is_enable) display_ticker.attach(0.004, display_updater); else display_ticker.detach(); #endif

}

// Set the color order {RRGGBB, RRBBGG, GGRRBB, GGBBRR, BBRRGG, BBGGRR} (default is RRGGBB) //display.setColorOrder(RRGGBB);

// Set the time in microseconds that we pause after selecting each mux channel // (May help if some rows are missing / the mux chip is too slow) //display.setMuxDelay(0,1,0,0,0);

// Set the number of panels that make up the display area width (default is 1) display.setPanelsWidth(2);

// Set the brightness of the panels (default is 255) //display.setBrightness(50);

// Set driver chip type //display.setDriverChip(FM6124);

then, should the issue be posted here? 🤔

P.S. https://github.com/2dom/PxMatrix

can you tell me whats the exact issue and why its not working , any changes in code to make it work properly?

This is not the place to ask about PxMatrix, this is rpi-rgb-led-matrix. Different software
