hello bro,
This code will definitely work i have used simple c language
#include<LiquidCrystal.h>
LiquidCrystal lcd(12,11,5,4,3,2);
int lenth,lenth1,i=0,temp;
char str[100];
char name[25];
void setup()
{
lcd.begin(16,2);
Serial.begin(9600);
}
void loop()
{
lcd.setCursor(16,0);
lcd.print("ENGINEERS GARAGE");
Serial.println("AT+CNMI=2,2,0,0,0");
delay(100);
lcd.setCursor(16,0);
while(1)
{
for(int j=0;j<400;j++)
{
serialEvent();
delay(1);
}
if(temp==1)
{
i=0;
lenth1=0;
lcd.setCursor(0,1);
while(i<lenth)
{
if(str_=='*')_
- {*
- i++;*
_ while(str*!='#')_
_ {_
_ name[lenth1]=str;
lenth1++;
i++;
}
for(lenth1;lenth1<25;lenth1++)
{
name[lenth1]=' ';
}
}
i++;
}
lcd.setCursor(16,0);
delay(10);
lcd.print(name);
temp=0;
lenth=0;
}
lcd.scrollDisplayLeft();
serialEvent();
delay(1);
}
}
void serialEvent()
{
while (Serial.available())
{
char inChar = (char)Serial.read();
str[lenth]=inChar;
lenth++;
if (inChar == '\n')
{
temp=1;
}
}
}*_
