BaseBall pitching Code sample - NewBie

[skimask]

Think of a 4 by 6 foot tic-tac-toe board. the center plate is the strike zone, all the outer plates are the balls zones. Each plate floats on springs and when hit, pushes on a switch. after 3 strikes, it goes to 1 out.. after 3 outs all leds are cleared, after 4 balls all leds are cleared.

That sounds reasonable. I'd put multiple switches in each box, one in each corner, one in the center, 5 per box I suppose...easy enough. What happens if you get 2 boxes (or 3 or even 4 in certain cases) with one pitch?

At this level, I just have two inputs, all ball hits are tie to one lead and the strike zone is lead #2. in the code I test for strikes first then balls. So strikes win in most cases. the layout is very basic. I'm looking for help on the circuit layout. Something very basic, just to prove it works.

I have tried to test this code and I can not get either of the switches RA.3 or RC.3 to fire off. Dose anyone know why? Are the registers set correctly?

Put a meter on the pins to make sure they're actually changing states?
Registers appear to be set correctly, that is if you are using the same code you posted in the zip file earlier.

The Inning isn't over just because you Walk somebody.

If balls = 4 Then over

<hr>
Do you have pull-up resistors on RA.3 and RC.3 ?
Is the PIC even running? Can you Blink an LED ?

OK, folks I include a layout of the chip and what I'm trying to do.
I used the paint program, It's all I have to draw with..

Again it's a PIC16F684 e/p

Thanks!

Have you configured MCLR as internal in your code?
Are you sure you have the A/D pins set up correctly for digital?

Also, I'm not so sure that:

sled var porta
oled var portc

will work the way you want it to.
