IMPLEMENTATION OF MOBILE PHONE
1. Introduction:-
In this communication project we are designing codes for GSM
 for attending the call
 for making the call
 for accessing the phone book
 for sending the SMS
In this project we are designing the code in ‘C’ for above three applications. Then by using KEIL software we are converting these ‘C’ codes in hex file. After converting we burn this hex code in 8051 microcontroller kit with the help of FLASH MAGIC software and then with the help GSM modem we do these operations.
2.Equipments used and their description:-
Equipments used:-
In this project we are using these equipments
 A personel computer
 8051 microcontroller kit
 GSM modem kit
 SIM card (suscribers identification module)
Software used :-
We are using
 KEIL software for converting the ‘C’ code in hex code
 FLASH MAGIC for burning this hex code in 8051 microcontroller
Description :-
8051 microcontroller kit:-
 It provides many functions (CPU, RAM, ROM, I/O, interrupt logic, timer, etc.) in a single package
 8-bit ALU, Accumulator and 8-bit Registers; hence it is an 8-bit microcontroller
 8-bit data bus - It can access 8 bits of data in one operation
 16-bit address bus - It can access 216 memory locations - 64 KB (65536 locations) each of RAM and ROM
 On-chip RAM - 128 bytes (data memory)
 On-chip ROM - 4 kByte (program memory)
 Four byte bi-directional input/output port
 UART (serial port)
 Two 16-bit Counter/timers
 Two-level interrupt priority
 Power saving mode
