Savining a Hex file in MPLAB

Does anyone know how to use MPLAB to read the hex code out of a non
code protected pic chip and then to save that to a hex file.
Under "Programmer" there is a "Read" command but I don't see any way
to save it or even display to data that was read. I've gone thru the
help and doen't see anything.

Thanks in advance

Read the chip so that its code comes up in the editor, then from the
File menu
export or save as..

Sure, read it in using either the "arrow in" icon or the menu item.
Then export it (file menu item) as the type of hex file you want.

Make sure that you have the "Program Memory" window visible /
enabled. You will find this under either the "View" or "Window"
captions at the top of MPLAB (depends on which version of MPLAB you are using).

You should also have the option of displaying disassembled code as
well. I **think** you might have to right-click on the Program
Memory window to see that option. Again, depends on which version of
MPLAB you are using.

Hope this helps.

If you cannot disassemble it send it to me with the chip number it
comes from and I'll see what I can do.

Try exporting the .hex file(file menu) once you have a successful read.

I'd suggest you do this as a two step process:

1) Create a .txt file detailing the contents, name it the same as the file
- describe microcontroller, date, function of program, any other notes.
-
2) Export the .hex file.

If possible create a sub directory with those two items. You will save yourself much grief later when you try to figure out what version it was.
