HEX Checksum Generator for PIC18
PostPosted: Mon Oct 03, 2005 2:05 pm     Reply with quote
I've just created a program for generating checksums of HEX files. It should be useful if you want to verify the program memory when the code protection is on. The generated checksum is not a CRC, it's only an additive one. The resulting 16 bits are stored in the ID section of the PIC. You can find more details by executing the program in command line (it's windowless). Please report any bugs you find, I haven't had enough time for serious testing. It looks like it works ok on PIC18452, i've tested it in a hurry. For the moment, the program works only with PIC18Fxxxx.

I have updated this program a while ago. It can now create a CCS verification routine automatically for direct use in your programs.

It is now production tested on 18F452.

Help is available when you run it in command line with no parameters.

Download from here.
