Hi,

   

I am trying to connect the output of a UART to Pin P1[7], but I am getting no output.  If I connect it to P1[6], then I can see data coming out of that pin.

   

As far as I can tell, I am not using P1[7] as VREF. I have no ADC in my project, but I do have a Comparator.  I can find any option that lets me disable the VREF function for P1[7].

   

How can I use P1[7] as a digital output?

   

Many thanks

It might be that P1_7 is bypassed with a 1µF cap. Please check schematics of your board.

Hugo here is a picture of the Pioneer PSOC board and you will see why you can't use it for a Digital signal.
