Debugin

[tbh9365]

I am using the adcin command for my anolog inputs, and the debuggin command should
make the pin an input. I don't have cmcono or ansel in my program anywhere.

Oh, DEBUG will make the pin an input all right, but only if the pin is selected as an input.
Read the datasheet for the 16F648, page 31 of DS41202F, the note highlighted on the right side of the page.

I don't understand how to set these registers, I have the RA1 pin set as Vref,
and RA0,RA2,RA3,RA5 as anolog inputs. I am trying to use RA4(an3) as the debugin
pin. My registers are set as follows:

cmcon0 = %11110000
ansel = %10101
adcon0 = %01001000

How far off am I? And what do I need to change?

Thanks

And more information that would've been a lot more helpful much earlier in the process...

You're trying to use RA4/AN3 as a digital input, which means you aren't using it as OSC2 or a Fosc/4 clockout, which means you are most likely using the internal oscillator, which means that it may need to be tweaked a bit to get the baud rate correct (see OSCTUNE)...and do a search on that term.

Am I about right here?

You are correct, I am using the internal Osc. on the Pic 16F684, and a Ceramic Resonator on
the Pic 16f84A, of 4mhz, And the internal Osc should be 4mhz also on the 684, I will double
check this. I will also read up on the tuneing and give it a try. Thanks again
