hi everyone!!
i m an amature, beginning to work with PICs. i want to know about an
apropriate programmer and a proper compiler which is capable of
converting a software written in C language. are there relevant
websites??? and is the compiler freely availaible???? where can i get
the circuit of the programmer??? can anyone help me regarding this??
cheers!!

I found the following download site on the
www.Microchip.com website:
http://www.htsoft.com/downloads/demos.php
Some of them are freeware, but may not support the device you have chosen to
use. Also, I think I tried one of the Hi_C compilers, and it was a DOS-like
console application, not a friendly IDE.
I purchased a full featured Microchip C18 compiler for about $200, when I
planned a really major project using a high end PIC. But up until now I have
written everything in assembly. It is important to know what goes on at that
level in order to fully utilize higher level language tools. You might also
look at Microchip's Application Maestro, which essentially writes some of
the code for you in response to a series of questions, like a "Wizard".
There are also many application notes and software examples and libraries
that are free for the downloading.
You should start with something like their PicKit which has a built-in USB
programmer for a PIC16F676, and there is an extender board to allow other
PICs to be programmed. It costs about $35. I also have an ICD2 debugger tool
which is absolutely essential for serious development, and costs around
$150.
It is important to know what your C program does (if it is already written),
and what platform it is designed for, to determine the best PIC controller
for the job, and what sort of I/O is required. It is possible for a PIC to
read a keyboard, generate a GUI on a CRT display, interface to a hard disk
drive, etc., but you will need a *lot* of external I/O and a low level
operating system on the PIC to implement the associated C functions.
Good luck!
