hello, i am a college student,and i have a project now which is about the communication between PIC16C745 and GSM MODEM. The background is that the user send a serial of digits through handphone to GSM MODEM . I must receive the digits and decode the digits thus let the LED TRUN ON/OFF within the time interval(example) so now the problem is that i don't know how to write the source code to decode the digits from GSM MODEM. The PIC and GSM MODEM are connected through pin 17 and pin 18 (TX,RX).
The format of the serial digits are "4digits password(preset)+ start time + stop time" (the format of time is 24hrs),
eg. 000008302330----so, 0000 is the password; 0830 is the start time; 2330 is the stop time.
So, please help me! Thanks !
Any response will be highly appreciated. My E-mail: zacharias98@hotmail.com
