@salmanfaris Rewrite all code and uploaded. But SMS is not displaying correctly in LED Board, .. I'm attaching code and display output. take a look ,
#include <SoftwareSerial.h>
#include <SPI.h>
#include <DMD.h>
#include <TimerOne.h>
#include "SystemFont5x7.h"
#include "Arial_black_16.h"
#define ROW 1
#define COLUMN 1
#define FONT Arial_Black_16
DMD led_module(ROW, COLUMN);
String st;
const char *msg;
unsigned int LengMsg;
SoftwareSerial mySerial(3, 2);
void scan_module(){
led_module.scanDisplayBySPI();
}
void setup() {
Timer1.initialize(2000);
Timer1.attachInterrupt(scan_module);
led_module.clearScreen( true );
Serial.begin(4800);
mySerial.begin(4800);
Serial.println("Starting...");
delay(1000);
mySerial.println("AT");
pollSms();
mySerial.println("AT+CMGF=1");
pollSms();
mySerial.println("AT+CNMI=1,2,0,0,0");
pollSms();
}
void loop(){
pollSms();
delay(500);
//Start print in led matrix
led_module.selectFont(FONT);
led_module.drawMarquee(msg,LengMsg, (32 * ROW), 0);
long start = millis();
long timming = start;
boolean flag = false;
while (!flag){
if((timming + 20) < millis()){
flag = led_module.stepMarquee(-1, 0);
timming = millis();
}
}
}
void pollSms(){
delay(500);
while (Serial.available()) {
mySerial.write(Serial.read());
//String st = String(Serial.read());
//Serial.println(st);
}
while(mySerial.available()) {
Serial.write(mySerial.read());
st = String(mySerial.readString());
Serial.println(st);
LengMsg = st.length();
st.toCharArray(msg,LengMsg);
}
delay(500);
}
output video : video link
