Greetings all,
I'm currently planning a project that will use a PIC to talk to a
computer via USB. According to the Microchip chart, the appropriate
units are the 18F2455, 18F2550, 18F4455, and 18F4550. I've built Myke
Predko's El Cheapo programmer; however, his page (myke.com) indicates a
very limited number of PICs supported by his software. It seems lots of
people here like Wouter's Wisp628. It doesn't seem too hard to build,
but his site seems to say that while it supports a lot of PICs, it
doesn't support any of these four PICs I mentioned above. Is this true?
If so, would (politely) bugging him make it support them in the near
future with little or no hardware modification to the circuit?

Also, my only programmer at this point is the aforementioned El Cheapo.
Myke's page indicates that it supports the 16F628, and Wouter's page
indicates that the Wisp is powered by a 628. However, Microchip's page
no longer indicates the existence of the 628; apparently, it has been
replaced with the 16F628A. Will the El Cheapo program 16F628As, and will
a 16F628A work in the Wisp? How about other similar chips (I have a few
free samples from Microchip which are IIRC 16F648As or 16F684s).

What would everyone suggest?

Thanks for your help,
Chris
