Newbie here. I have an idea of a backboard that a baseball pitcher can throw at and it will display strikes, outs and balls... with two switches.
Being my first time trying this can you all take a look or better yet try it on a test board ? I do not have my parts ordered yet and would like to get a idea of what I'm needing.. I have based the code on a 16f684 chip.
Include is baseball.zip
My question is...how are you going to do all of the sensing in and out of the strike zone? Pressure switches, light beams?Quote:

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?Quote:

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?Quote:

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?Quote:

Also, I'm not so sure that:
sled var porta
oled var portc
will work the way you want it to.
Here are a couple of options, some are freeware, others offer free versions with reduced capabilities/personal use only.Quote:

I'll remove sled and oled and replace with porta, portc
You are talking about the "CONFIG: CONFIGURATION WORD REGISTER"
bit 5 - 0 = RA3/MCLR pin function is digital input. Right?
Now that I need to set the CONFIG REGSTER, any help with the other 15 bits?
Thanks SteveB, I look into these. Great Help guys!
