1.Set a flag in the Eeprom on start up then load the 5's in unless the flag
has been set before

2. Don't do it in the code. Pre load the EEprom at program time.

Subject: [PIC]: part of program only once


Hi all!

I'm building central heating controller. In INIT phase of my program there
is a few instructions that preload first five EEPROM locations with number
five. What I'd like to know is: how do I tell the PIC that it should execute
this part of program only at first go after programming the PIC and that it
shouldn't touch EEPROM in INIT phase after any kind of reset. Is it POR or
BOR bit that I should test?
I'm using 16f877.

Thanks in advance, Samo
