Objective :i have created a 64 X 32 display using 8X8 dot matrix for which i am using MD parola library to print multiple charcters big, small, special , graphics etc
Platform : aurdino on proteus
Schematic : PDF attached
Code :
#include <MD_Parola.h>
#include <MD_MAX72xx.h>
#include "Font_Data.h"
#define MAX_DEVICES 16
#define MAX_ZONES 2
#define ZONE_SIZE (MAX_DEVICES/MAX_ZONES)
#define CLK_PIN 13
#define DATA_PIN 11
#define CS_PIN 10
MD_Parola P = MD_Parola(CS_PIN, MAX_DEVICES);
void setup(void)
{
Serial.begin(9600);
delay(2000);
P.begin(MAX_ZONES);
P.setInvert(false);
P.setIntensity(0);
P.setZone(0, 0, ZONE_SIZE-1);
P.setZone(1, ZONE_SIZE, MAX_DEVICES-1);
}
void loop(void)
{
delay(1000);
P.setZone(0, 0, ZONE_SIZE-1);
P.setZone(1, ZONE_SIZE, MAX_DEVICES-1);
P.setFont(0, BigFontBottom);
P.setFont(1, BigFontUp);
P.displayZoneText(0, "aaaaaaaaaaaa", PA_CENTER, 30, 0, PA_PRINT, PA_NO_EFFECT);
P.displayZoneText(1, "aaaaaaaaaaaa", PA_CENTER, 30, 0, PA_PRINT, PA_NO_EFFECT);
P.synchZoneStart();
while (!P.getZoneStatus(0) || !P.getZoneStatus(1))
P.displayAnimate();
}
Problem:
but i am facing a problem as in shown in image
mainly i am not able to view what so ever displayed in the last 8X8 module
this problem follows a pattern if i add some more matrices
now the same problem if i add more 8 matrices like below
