"It used to be that the number of different microcontroller chips available to the hobbyist was pretty limited. You got to use whatever you could manage to buy from the mail-order chip dealer, and that narrowed down the choice to a small number of chips.

But times have changed. Digikey lists over 16000 different line items under a "microcontroller" search. Which one should a hobbyist with no particular prior experience choose?

Here are some hints. These are particularly aimed at someone trying to pick a microcontroller to use for the first time at least partially as a learning experience, rather than someone who wants to accomplish a particular task."

Very good info Alan. I know I have received a PM or two asking about stuff like this.

The only thing it didn't mention that I wish it had was that much cheaper "knock offs" for high dollar equipment like the ICD2 are available at a tenth of the price, and they usually work just as well.

That would have been a great thing to add. I got a MElabs programmer, and later realized that for the price I paid I could have gotten a full ICD. Oh well, live and learn.

Not to mention that all of Microchips programmers are not compatible with every chip. That is an important determination to look at when buying a programmer. For instance, my PICKit2 wont do a lot of what my ICD2 will do.

Do you folks have any advice on the best PIC programmer to purchase? I'm a rank amateur but I'm looking towards something that will let me start small, but will allow me to work with the more advanced processors later on.

Is the ICD2 the way to go? I'd rather go with a USB system, but at this point I'm willing to take what I can get. Price is a major concern (Former fed, now a college student), but something that I can probably save for.

What about these programmers on eBay?

Well, I am not sure what exactly you are going to be working on, but the ICD2 was a good start for me. The one I got was a knockoff ICD2 on Ebay. Be careful though, there are a lot of programmers out there that can't supply the needed power. You can always build your own, but the major problem is always how to set up the ICSP header.
