Writing internal EEPROM data while programming
PostPosted: Thu Nov 08, 2001 8:01 am     Reply with quote

Does someone knows how to program some data into the internal eeprom while programming a chip. I'm currently working on the PIC16F877. Is there a specific keyword to use. I know the write_eeprom command that can be executed while running. I need to initiate each microcontrolor with a serial address and do not want to do it while running.

#rom 0x2100 = {125,200,90,11,124,28,204,210,113,250,231,223,114,250,231,223,138,10,143,139,4}
first 21 bytes of ROM are loaded during programming.

Why do you use 2100? is it the base address for the EEPROM?? wich chip? is it for the 16f877??

Read the last part of page 3 of the PIC16F87X data sheet.

That's the PIC16F87x EEPROM Memory Programming Specification.
