A/D, Pot, Input, A,B So lost now....

Wow, skimask, you must _live_ on this forum

Nope, just passing by every few minutes in-between work benches and/or projects... Keyboard is at waist level. Easy to type...

wow, thanks for the reply.

But damn now Im lost.

Can I just read the AD converter value to a byte? Then use that as my pulse out. I think thats what that code above is doing, but also applying some limits and boot up procedures.

I guess where Im getting most lost is how do I define what I am using on that pin? Or Will it just read what ever it wants to? Do I have to write it to a data spot or can I just use it as a variable?

Servo VAR Portc.5
Potin VAR AD.4 ' Can I do that? Or Do I call it something else to call the AD converter inside the pin.
PULSE VAR BYTE


Loop:
READ AD.4, Pulse
PULSOUT Servo, Pulse
Pause 18
Goto Loop

Thanks again, Sorry I am new at this. Im trying.

EDIT: Ok so super noob question, Is there a difference between calling a PIN by GPIO.? versus Porta.? or Pin 5. I get the port/pin references but I can seem to figure out where the GPIO comes from.

Hello Helmutt,
Yes, GPIO is for the PICs that have GPIO like the 12fseries as they only have 1 port. PortA, B, C are assigned to the ports you actually have. I E. a 16F628a has 2 ports, A & B, whereas another PIC might have several more A B C D . . .

Ah cool, Finally stopped skipping over the 12 pin section and found that out. Thank you.

Easy way...if you left justify the results, you can use the high byte of the result and use the upper 8 bits (low 2 bits ignored), if you right justify, you read both high and low byte of ADRES into a word

As far as how to use the A/D converter, read the manual. There's an example in there, and while it doesn't fit all scenarios, it fits many of them.
