Pickit 2 saving varables?
Hello Everyone,
I can't seem to get my 18f452 to save variables to the eeprom, I've posted this here because I'm thinking this has something to do with the pickit 2 set-up and not the picbasic pro code. I've used these same routines before to save to the eeprom and it has worked good in the past. I have the "Program Memory" and the "EEprom Data" boxes selected for hex only but have tried other settings as well with no success. Can anyone here in the know suggest what settings need to be looked at in the pickit 2 in order to get this code to work properly? Any help will be greatly appreciated.
Thanks
jessey
