P10 red 63 panel using 112 pixel height clock issue

[maxmurugan]

hi sir I am using 63 panel p10 module used

define DISPLAYS_ACROSS 9

define DISPLAYS_DOWN 7

maximum support DISPLAYS_DOWN 3 working more then DISPLAYS_DOWN 3 not working

please check my code below sir, /*-------------------------------------------------------------------------------------- Demo for RGB panels

DMD_STM32a example code for STM32F103xxx board ------------------------------------------------------------------------------------- */

include "DMD_Monochrome_Parallel.h"

include "st_fonts/Arial_79.h"

pragma GCC diagnostic ignored "-Wnarrowing"

pragma GCC diagnostic ignored "-Woverflow"

//Number of panels in x and y axis

define DISPLAYS_ACROSS 9

define DISPLAYS_DOWN 7

define ENABLE_DUAL_BUFFER false

define DMD_PIN_A 10

define DMD_PIN_B 11

define DMD_PIN_nOE 14

define DMD_PIN_SCLK 15

uint8_t pins[] = { 6, 7, 8, 9,16,17,18,19}; // CLK , row1, row 2,, row 3 DMD_Monochrome_Parallel dmd(DMD_PIN_A, DMD_PIN_B, DMD_PIN_nOE, DMD_PIN_SCLK, pins, DISPLAYS_ACROSS, DISPLAYS_DOWN,ENABLE_DUAL_BUFFER); DMD_Standard_Font arial_9(Arial_79);

int Hour =06; int minute1 =34; char a[10];

void setup(void) { dmd.init(); Serial.begin(9600); delay(100); }

/-------------------------------------------------------------------------------------- loop Arduino architecture main loop --------------------------------------------------------------------------------------/

void loop(void) {

dmd.selectFont(&arial_9);
dmd.setBrightness(100);
Serial.print("WELCOME PICO P10 RED");
while (1) 
{
                  sprintf(a,"%2d:%02d",Hour,minute1);
                  dmd.drawString(0,0,a,strlen(a),1);
                  dmd.swapBuffers(true);

 }

}

Hi You have a problem with your row pins:

uint8_t pins[] = { 6, 7, 8, 9,16,17,18,19}; // CLK , row1, row 2,, row 3...

On Raspberry Pico all row pins must be in ascending order, without gaps. So if you started from "6,7,8,9", the next pins must be 10,11, 12... etc

ok sir i will try

Tested for width - 9 module and height - 7 module as per your pin detail working perfectly.. thangs for support.
