Hi guys,

I have reviewed very attractive piece of hardware, Inchworm ICD2 programmer/debugger. Please click here to see the review. I hope you will find the review helpful. Any comments are welcome.

Jay.

Thank you for the review Jay, I've made changes to the manual and removed the 24F & dsPICs from the supported chips list (they are 3.6V max chips)

Hi,

First post.

Does the kit come with the separate pc board with the ZIF socket? If not, where do I purchase one of those?

Thanks,

John

**Jay.slovak** · 7th November 2006, 08:28 AM

No it doesn't. The one you can see on the last picture is of my own design.
But, there is going to be a companion board for the Inchworm, with ZIF socket and many other interesting parts.

If I purchase kit #1, how would I be able to interface a PIC to program it? Is there a simple design that I can build to be able to use the programmer now? I'm new to PICs and just ordered the kit so I need a daughter board for the actual PIC.

If it's any help?, here's a version of my 16F876 tutorial board with an InchWorm ICD socket added.

Hmm.....forgive me as I am new to some of this. I've build simple electronics projects so the construction is not a problem but I want to ensure I haven't misunderstood anything.

Your schematic is for a simple programmer or a board I can connect to the Inchworm kit?

Again, forgive my confusion.

**Nigel Goodwin** · 7th November 2006, 10:05 AM

It's a processor board - used in my PIC tutorials - I've added a socket so it can connect directly to an InchWorm programmer/ICD.

jduncan459 · 7th November 2006, 10:27 AM

Ok. So I can add a ZIF socket to it and I'll be all set then?

**Nigel Goodwin** · 7th November 2006, 10:53 AM

Only for programming 28 pin pin PIC's, different size PIC's use different pins, you need to wire a ZIF socket so it can take various PIC's in different positions - being careful not to place 13V on a pin you shouldn't!.

jduncan459 · 7th November 2006, 12:28 PM

I'm not sure how to wire the ZIF so that I can use the different chip sizes so I guess I will wait for the Firefly companion board to be released. I think it will be easier to learn the programming on a less complex chip than a 28 pin, although I think I'll need the functions of one eventually.

John, I totally agree.

Inchworm with Firefly should be a very good combination for beginners.

jduncan459 · 7th November 2006, 05:24 PM

I've studied the schematics for a bit and see how it's wired so I can make a pcb for the pic chip until the Firefly is available. Never study schematics until you've had at least two cups of coffee.

Or, just do your test circuit on a Breadboard. That should be easy and fast. PIC requires minimum external components, you should be up and running in minutes.
