USB PIC Programmer - Steven - Sep 24 12:35:00 2003


Has anyone had any experience with USB based pic programmers?

I have been using a modified NOPPP but the programming speed is
getting to be a hassle. It takes way to long to program a 2k chip.
The chips that I am using are the 16F628,877,84/A.

If anyone could express there opions on these programmers I would be
thankful.

Do you want ICSP or ex-circuit? Wisp628 is a serial port ICSP
programmer, works fine with either a standard USb-to-serial converter or
an FT232BM chip.

I have looked at the KIT149 that a few places have carried but I
can't find any reviews. I would like a more stable development
system then the little programmer that I have been using.

What are the good serial programmers that are out there?

It's not about need, Wisp628 is about tyhe cheapest reliable programmer,
but it does flash ICSP only.

Just about any programmer that is not serial-port powered or
parallel-port based will probably be more stable. Note that the point is
serial port *powered*, not serial-port based in itself.

> What are the good serial programmers that are out there?

a few: Wisp628, WarpXX, KIT149 (+another one in that series), PicStart+
(not updated for all flash PICs yet).

Being able to program the PIC while it is in the target circuit is a real
help. Having to move the PIC between the target and the circuit for every
small change becomes a real pain after a while and sooner or latter
something (usually the PICs leads or the chip carrier in the target) will
break or become unreliable.

I don't understand what all the fuss about USB is either. Sooner or later a
PIC "experimenter" is going to want to get the PIC talking directly to a PC
and 99.9% of the time s/he is going to want to do it using RS232. Anyone
that doesn't have an RS232 serial port on their machine can either get a USB
to RS232C converter or pick up a second hand machine really cheaply on ebay
(sometimes for less than the cost of the converter). BTW you can also buy a
brand new Cybiko (with RS232, graphics LCD, keyboard and RF comms) for
around 20 GBP (about 30 USD) and use that as a dedicated terminal or
intelligent LCD for your serial enabled PIC project.
