Help me please for my project.

@kirangowle
i download your GSM notice board LCD and got confuse with this

bit flag1=0;
unsigned char store[10];
bit NewMessage = 0;
bit TI_flag = 0;
bit flag=0;
bit No_correct=0;

what does that mean?
thank you

bit is a special datatype in keil. read more about it in keil tutorial.

ok,i will look it up.

Also post your complete code (zip it) So that I can see what exactly you're doing. I would rather suggest you to use Kiran's code from project and modify it for your need. coz he is already doing reading part and everything. You only need to do comparison and send response after new SMS is received.

ok,ajay I will upload it soon..
now I am still modify it according to my need.
thanks a lot for your help.

hi ajay,sorry for late reply.
here is the code,i just tried to make a simple code which supposed to send sms when it is connected to powersupply but it didn't work i used xtal 11.0592 with baudrate 9600.
please give me correction.

here is my schematic

C6 and C7 should be 1uF, the same as C4 and C5.
I assume your real circuit has power connections to pins 15 and 16.

in the real circuit already 1uF,so all of the 4 capacitors value are the same.And the power connection also already connected.
But it still can't work how about the code?

You must initialize serial communication first before you can send anything to modem.

void main (void) {
	initialize_serialcommunication();
	initialize_GSM_modem();
	while (1);
}

Make sure delay2 should be more than at least 500ms.
