Serial Number in PIC Basic Pro

[Keith03]

RESULT:

Slightly modified, I got your solution to work! I am so grateful for your help! This is exactly what I was looking for. I was able to find the pattern in the HEX file (with a regular expression).

Now the real hard part. I will need to locate the pattern and replace it just prior to programming the device. It tends to span lines in the HEX file and there are checksums to contend with. I am going to look and see if there is a way to tell the assembler to split out this line(s) in the HEX file. Then I just have to parse part of the file. Regardless, I can parse and rewrite the whole thing if I need to.

Thanks again! I am truely amazed. Now that I am a member, I will check back periodically and see if I can help others in their endeavors.

Regards to All,
Keith

Exactly the reason why many modern MCU's have a built-in unique 64-128 bit ID. These IDs can be read during programmming and/or runtime (but cannot be overwritten/erased) giving you total control over your part.

And yet *ANOTHER* reason to use only 18F chips. Using them, it is relatively easy to put a serial number in codespace, (above MCLoader, if you use that program) or in the userID section.
