help with development kit - castcastus - Oct 30 13:54:00 2003


Hi,

I would like to buy an PIC development kit WITH ALL the things that I
need to develop some new projects. If that kit has a C compiler,
that would be great.

The first project that I have to develop needs communication to 2
serial devices (RS232) and a few parallel input/outputs, and I would
need the kit mainly to develop this project.

Additionally what would be a good PIC for that ?

Thank you in advance.

Clement

Why on earth would you want a kit that includes a C compiler? Even
Microchip offers their C18 compiler and various evaluation boards
separately.

Every PIC you can think of, so you will need to specify more details.
One-off or a 100k series? How much processing? How much other I/O? Which
asynch speed? etc.

Wouter,

I'm just starting with pics and I'm trying to find out some usefull
information on that sea of data that you can get when you talk about
pics.

I have work a lot with the Rabbit microcontroller, but it's very
expensive for this particular project, am I'm trying to transfer what
I know to the Pic and I know nothing about pics.

With the rabbit I work with C language, that's why I was looking for
a C compiler for Pics. I don't want to work initially with assemmbler.

The project needs 2 serial ports, around 5 inputs, 2 outputs, no A/D
converter, and I will need strong debug capabilities, so I can see
what is the pic trying to do when is running my code.

Thanks,

Clement

HI,

I have experimented with 2 diferent C compilers. C2C-plus and wiz-
Z. c2c plus is cheaper and is consice. The drawback is that it doesnt
have a C level debugger although they say that is in the works right
now. If you buy their picant ide you can also connect plug-ins like
buttons and LCDs cost is about $65 maybe more
http://www.picant.com/c2c/c.html. They have a good forum page too to
help you solve those little nasty problems that pop up every now and
then. The wiz- C is a marvel. It is prety close to ansi C, has a C
level debuger, lcd, plugins, butons watch windows and everything the
c2c has. It also has a wave analyser and you can input conditions
from an external file. Example would be to change the level of a pin
after 300ms. For the price is reaaaallllyy good. the profesional
version is 100 british pounds. I got it for about $170 with shipping
and currency excahnge. http://www.fored.co.uk/

this people also offer the kits you are looking for and will give you
special prices if you buy a combo kit. from here on the c compilers
get more expensive. From 500 and above, unless you get a free version
which has limits. for example the hitech piclite compiler is free but
has a 1kbyte maximim program size. Can't expect much for free.

Personally I have the e-pic programer and lab-x1 from melabs. the
same people that make the picbasic compiler. you need both if you go
with this setup and you can buy their picbasic compiler in a kit. The
catch is that is basic and not C but I herad goos thing from this
compiler. You could also go with matrixmutimedia board. they also
ofer the c2c C compiler and testboard kit combo. However is an older
version of the compiler and it doesn't have all the neat features
that you want.

The third option would be to build or buy el cheapo programer or
build your own testboard. I build one for the pic16f84. Pretty much a
few dip switches on portA and a led array for portB.

strong debug capabilities, C compiler => 18F series. IIRC there are
18F's with more than one UART but I am not sure. Otherwise implement one
in software, or add a slave PIC (a 16F682A for instance) as second UART.
For debugging: get yourself an ICD2. Note: I have one around but I never
actually used it. I guess I use a different debugging style: I prefer an
LCD connected to the PIC. Compiler: Microchips C18 demo works for a few
months (no other restrictions), then re-install :). IIRC it costs $500
when you realy want to buy it. Be aware of the clock frequency problems
with some of the 18F chips, do read the errata for the particular chip.
