Please let me know that I programmed Arduino code for save and restore of float values
in eeprom, Arduino eeprom library attached but problem is that when I write value
first time then value is successfully restore but when second time update the value
then restore take some for retrieving value?

24LC256 Serial eeprom,
I am using eeprom with I2C , and I use a lot of commands to make all addresses to zero state. Is there any method , so that I can completely erase all data in my eeprom at once ?

I don't see any references to eeprom I2C addresses in your code, thus I believe it doesn't actually access it.
There are other points like generating correct eeprom commands with address field, and required ACK polling after write actions. But that's next.

I am using pic32mx795f512l and i am trying to code for external eeprom (25LC256) to store the last value of LED.
I want to use SPI communication for eeprom. I need sample code to done this.
Please help me with some sample code.
Thanks in advance

So where in the data logger system,are you facing a problem?Is it in the code?
the date, time and temperature value should be written into the eeprom and pressing a button the written values should be read and displayed in lcd and hyperterminal
You mean the instantaneous value(s),right?and why would you be using both the hypertermina

I want to know how to write the adc result in successive address of external eeprom

Put a small delay between the second eeprom_Write and the first eeprom_Read:
Delay_ms(20); // !!!!!!!!!!!!!!
PORTC = eeprom_Read(2);

The code you posted above is not explicitly related to some IR Thermometer reading, and performs the task supposed to do: Just a sequential scan on eeprom content. Can you assure the memory is not entirely cleaned ?

Your basic steps would be the following:
1.) Setup your analog input ports and ADC parameters
2.) Cycle through the three channels with ADCON register
3.) Set the channel, read the ADC value, write to eeprom, update eeprom address, delay, go to the next channel
4.) The eeprom address you will have to increment and keep track of to know which (...)

Just a thought, PIC16F877A includes 256x8 bytes of eeprom in the MCU itself. Post the code with which you've tried, that way it'll be easier to debug rather than asking for full code to someone.
