Hello,
I am using the melabs epic win programmer.
I want to copy 1 microchip. I thought this would be easy
but I am not sure if I am doing it correctly.
I put the chip I want to copy in my programmer and click on read.
I then save the hex file.
I then put in a blank chip and load the hex file. I then click on program and
I assume that I have copied that chip but when I read the contents it does not match
my master chip.
Am I doing this right ???
Depends what you're trying to copy (and I think I know where this is going)...
There is such a thing as 'hardware copy protection' built into most PICs...and it's usually pretty good for all but the most hard-core hackers, and even then it's a crap shoot as to whether or not you'll get the real information contained inside a PIC.
Is there a way to know if the chip I am trying to copy is protected ??
Ask the person who programmed it.Quote:

How about some information!!!
It is a 28 pin PIC16F873,Quote:

We want to make a backup in case this one gets damaged
as it has in the past. Students use this equipment and we
know how they are.

There's a reason why these companies put copy protection on proprietary firmware...
It was worth a shot.
Didn't think the type of equipment was important but
it measures the "hall effect" of certain probes and
the manufacturer is Leybold.
