16F877A eeprom problem
PostPosted: Wed Jun 03, 2009 5:03 pm     Reply with quote
Hello everyone,
I have been focusing on a simple project that gets the values from the keypad and saves them to the eeprom. However, when the value reaches decimal 255, I can not save the value. Do you recommend any way?

A value of 255 shouldn't be a problem, see also the example program ex_intee.c

Values larger than 255 don't fit into a byte and here you have to cast the address pointer to an int8 pointer. See the chapter 'How do I write variables to EEPROM that are not a byte?' in the CCS manual, page 306.
