help with project

[goran]

Hi! I have to write C code for storing parameters T_H (high temperature) and T_L (low temperature) in serial eeprom (24C02) using I²C protocol, above and below which the buzzer will turn on. I use mc 89c51 and 7-seg led display (4 digits). I really need help! Thanks anyway!

Hi 

You can refer this project (1 link) to understand how to work with serial eeprom using 8051 microcontrollers. Another way that i will suggest you is to work with AVR microcontrollers like atmega8, 16, 32 etc. they all have inbuilt eeprom and its usage will become much more simple. Herer's a link for that too (2 link).
