Debugging PIC12F617

Started by Tony Rudzki September 10, 2010

All,

Is it possible to connect a PIC12F617 and debug it as you would any other
processor? The reason I'm asking is that it seems like they're pushing
using another processor in place of the '617.

Working on my prototype board and wanting the cheapest micro that would do
the job.

Tony,

The 8-pin PIC12F devices (including the PIC12F617) require a debugging
header from Microchip. The header is a board with a special version
of the PIC12F617 with in-circuit debugging pins brought out so you can
plug in an ICD-3 (I don't know if the PICkit-2/3 work with the headers).
The header has the 8-pin DIP footprint of the PIC12F617 (so your proto
requires a DIP footprint or a DIP-to-other-pkg adapter.

The AC162083 at $35 is the header for the PIC12F617.

There are some docs on the Microchip site about these kinds of headers
in general.

Without the debugging header about all you can do is program-and-try,
and even then you have be mindful of the in-circuit programming pins
and how to integrate them into the project without breaking anything.

Apparently this particular header can also work for the HV members
of that sub-family of PICs.

(I also don't know if an ICD-2 would work with the header but I
think it might)

I've used the special headers with an ICD2 and some other 8 pin part.

Yes, and I have used the AC162050 debug header for the PIC12F629/PIC12F675

with both ICD-2 and ICD-3. It looks (from the dates of some of the debug header

documents) that the AC162083 and probably all the rest of the debug headers

work with the ICD-2 as well as the ICD-3.

Hi Folks,

even if there is no debug function possible with the small PICs you have a
much better way then program and try: use the simulator of MPLAB and
debug your program.
