Hi,

i have write, simple code for write one byte and read it from internal EEPROM.

i have do it using MikroC 8051 with in built READ and Write function (using eeprom example given).

now i want to confirm ,is my byte really written ..

can i do it in debugger of mikro C or i have to burn my hex file in IC??

Thanks
 

Hi,

Don't you trust the EEPROM?
Or don't you trust the simulator?
Or why do you worry?

In both cases you need to put code on the microcontroller.

The classic memory verification test is made by writing-and-reading alternating patterns of 0 and 1, something like that in pseudo-code for each address mapped by index i :
Code: 
bool Success = false ;
WRITE_EEPROM ( ADDRESS(i) , 0x55) ;  // 0b01010101
DELAY
if ( READ_EEPROM ( ADDRESS(i) ) == 0x55 )
     {
     WRITE_EEPROM ( ADDRESS(i) , 0xAA) ;  // 0b10101010
     DELAY
     if ( READ_EEPROM ( ADDRESS(i) ) == 0xAA )
            Success = true  ;
     }
