WRITE data to EEPROM on PIC18F8621

[skimask]

well that should work fine, must be something in the rest of the program that isn't being shown, maybe a variable declaration, changing the variable itself in another part of the program, etc.etc.

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

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?

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...
