16F628 inicialization

[adrianrb]

Hi all.

I´ve trying to make some codes work on my 16F628 chip, but
noting happens... I saw in the microchip forum that chip needs
some initialization (source is in assembler, below).

Could someone translate (and explain, if possible) them to C
in order I use them in my sources? (I´m new in PIC world)

Tks in advance,

Adrian

Do you have the CCS compiler ? This forum is about that compiler.

You don't need to do any initialization in ASM code with the CCS
compiler. In some cases, the compiler will automatically insert code
to do the proper initialization. It will do this if you tell it to load the
library code to run a particular module, such as the serial port.
In other cases, you can call a CCS function to enable the Port B pull-ups.
But you don't need ASM code to do this.

If you don't have the CCS compiler, then you should ask the questions
on the MPLAB forum.

Here's a test program for the 16F628 written in CCS. It blinks an
LED on pin B0. It assumes you have a 4 MHz crystal, and that all
the other necessary connections are made (such as a pull-up resistor
on the MCLR pin, etc.)
