Problem with reading value from PIC16f873A EEPROM

[zeroskj1988]

i am using pic16f873a eeprom to store value. in ccs compiler i write program like this
ROM 0x2100={35,27}

hc=read_eeprom(0);
lc=read_eeprom(1);
to read eeprom


write_eeprom(0,hc);
write_eeprom(1,lc);
to write eeprom


when i complete one cycle of this operation, iam not able to read the lc value.but no problem eith reading of hc
can any body point out what is the problem with this program.thanks in advance

Re: 16f873A eeprom error

Which address are you ucing for hc and lc when writing to eeprom?

The answer to your problem is right in front of your nose :smile:

HINT: 0 (zero)

i think the problem is not with eeprom.some times when error value shows,i just switch off and on system.on again reading eeprom no problem with eeprom. so what is the problem with this pic(16f873a) thanks inadvance
