MAX6662 problem

[offspr]

Hello,
I wrote this MAX6662 routine for a PIC16f876A :

[PCM programmer]

Your basic problem is this line right here:

#use fast_io(a)

When you use "fast i/o", you must define the i/o port direction
by using a set_tris_x() statement.

You have some set_tris_x() statements at various places in your
program, but in many cases you are using output_low() or output_high()
without first setting up those pins as outputs.

Because the PIC pins are configured as inputs upon power-up,
you must configure the pins as outputs before using those functions.
(This is only true if you are using the "fast i/o" mode -- which you are).

You need to setup the tris, at the very beginning of main().
Do it before the while() loop. You can change the direction of
the DQ pin later in your program with a set_tris_x() statement,
but you must setup CLK and RST as output pins at the very
start of main(). Note that because these signals are on different
ports, you will need to set the tris for both Port A and Port C.
