12F683 serout timing

Hello Hobie Cat,
Make sure the idle state of the ports are correct for the communication mode you are using. TRUE data idles HIGH and requires a pull up resistor. INVERTED data idles LOW and requires a pull down resistor.

Hi Hobie Cat

Just did a forum search on "12f683 serout" ..plenty results like this one

Hello Joe and Dennis,

Thanks for the ideas. After an exhaustive day of the same results I gave up and took a nap. When I came back I tried a new chip and it works just fine.
So, I guess somewhere I messed up some internal thing while programming maybe? The rest of the functions of the chip seem to work fine on all the ports just no correct serout on any port.

I'm glad I bought a bunch of chips when I was doing the buying... Sorry to waste your time

Hey Hobie Cat

Glad you solved the problem :-)

Check my thread regarding a 16F690 ...
I still haven't resolved my problem on that one .. I eventually decided to try a different chip so also (temporarily) just gave up on it.
I intend to get hold of another 16F690 to eliminate whether or not it's the chip or not.

Thanks for the info and update :-)

Keep well
Dennis

#1. Glad you have it working, a nap's almost always a good idea.
#2. It's never a waste of my time if you make me think. Helps keep the machinery oiled and besides, I cannot even see my bench right now, I don't want to get too rusty.
