PIC IDLOCS and CCS
PostPosted: Tue Jul 24, 2007 6:02 pm     Reply with quote
Hello everybody.

Could you explain me how to read IDLOCS that is said to consist of Uniqie ID of a PIC? Let's say I'm talking about 18F family.

Actually, is this word stored in a program memory? If so, this requires to be also programmed with a desired ID? Am I right?

Could anyone elaborate on IDLOCS? What's that exactly and how to use this in CCS?

Cheers,
Peter.

I've read this and have still a few of questions.

1) The Device ID World at 3FFFFE-F identifies version of a chip and cannot be overwritten. Is this right?

2) The ID Location at 0x200000-7 is meant to be set up as a Unique ID by myself. I understand that for a process of bulk flashing of chips this could be automated so not to use write_program_eeprom with altered arguments ... If so, how?

3) Is there actually any Unique ID in PICs already stored somewhere so to avoid programming this and just read it?

Thanks a lot.

Just few more questions. Since the ID Location address is 0x200000-0x200007, this gives 16 bytes long ID. Is that right? Can I read this by: read_program_eeprom(0x200000L) - and so on? Actually, writing by write_program_eeprom just causes there are 0 values when reading ... So, the question is how to set up this ...

Cheers,
Peter.
