Epic Programmer
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.Originally Posted by forzaazzurri

Always wear safety glasses while programming.

One way is to try and read it and get garbage...or all $ff or all $00...
What kind of microchip are you trying to copy? What part number? What company provided this chip?
How about some information!!!

It is a 28 pin PIC16F873,
It is found in one of our physics equipment.
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.

rotsa ruck raggy...
Probably not going to happen...
Physics equipment is a bit vague, don't you think?
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.
