WRITE data to EEPROM on PIC18F8621

[dschafer]

No, that is not the case, I have checked over the code many times.

One thing I did notice is when I program the PIC the fuse settings for 'EEPROM table write protect' and 'CONFIG table write protect' are both DISABLED, But when I read the HEX, EEPROM, and fuse data back to the PIC programer both of those setting are ENABLED.

High likely it's down to your PIC programmer. Which one?

I use the DIY K128 v141204

[mister_e]

and which software?

and which software?

MPLAB IDE v7.21

The K128 programer has its own software

maybe it worth to visit their forum and ask?

I think you're on the right track.

Just tried loading the program again, both settings disabled.
did not power up the PIC
read rom, eeprom, fuse data, and both setting are already enabled.

also tried inverting these settings as you sugested but they read the same (enabled)

will look further at the programmer K128 possibly require updated firmware.

Thanks for all the help, will let you know how I go.

Of course it's never the program writer's fault, is it?

One thing I did notice is when I program the PIC the fuse settings for 'EEPROM table write protect' and 'CONFIG table write protect' are both DISABLED, But when I read the HEX, EEPROM, and fuse data back to the PIC programer both of those setting are ENABLED.

So set them so that the 'protect' options are enabled, read them back, see if they're disabled, and try the program again. Maybe the software for the programmer is bass-ackwards...
