Hi to all list!!!

Opsss!!! your topic is all about C compiler. Can I join?

If so, I have a PIC C Compiler demo but my problem is that I don't know how
to start with because this is the first time I'm going to use C for
embedded. Actually, I know to program turbo C/C++ in a PC. In terms of
Embedded C there is a different from Turbo C especially in handling standard
input/output.

With this, Is there anybody can share a sample program of PIC C (for 16F84)
with comments so that I can understand more on programming approach of PIC.


Best Regards,
