write_eeprom limit problem
PostPosted: Sat Jul 03, 2010 2:31 am     Reply with quote

Hello, I try to write internal eeprom(18f452) as big than 255, but I can't. It means when I try to write eeprom 1020 adc value; I can not. Everytime pic eeprom is saved 255...what is wrong? (I defined adc values as int32).

Knowledge is power...please read the PIC datasheets !
EEPROM is designed as BYTES, not Bits, Words, or Long words so you must access that memory area as Bytes (8 bits).
It is a simple task to 'split' the Word or LWord data into Byte sized 'chunks' to store.
There have been several examples here in the past to handle this.

and, the code for doing this is supplied with the compiler. Look at the file 'internal_eeprom.c'.

Best Wishes
