Hello all,

i'm trying to write data into the EEPROM of the PIC 16f877A.

I use the CCS-Compler Version 3.219 and an 16f877a with 368kb memory.

as i want to use the eeprom to store static data i want write into and
read from the eeprom. i used the "internal_eeprom.h" from ccs but with
no result, i can't read an write anything.

can someone post some code example to read and write? do i have to use
"#org"?

please help me!!

You don't need to do anything other than use the built in functions to
read and write the internal eeprom.

value = read_eeprom (address)
write_eeprom (address, value)

address = 0x00 - 0xff, for the 877
value == 8bit value to write into the eeprom

Remember, these commands (especially the write) may take several
milliseconds to complete.
All of this is available from the IDE and the manual.
