An open-drain or open-collector output pin is driven by a single transistor, which pulls the pin to only one voltage (generally, to ground). When the output device is off, the pin is left floating...
I've misunderstood/misinterpreted the data sheet before. :D Seriously, I read the EUSART section and my eyes gloss over when they start making distinctions between half-duplex, full-duplex,...
The USART section in the datasheet for your device will tell you if you should set/clear the TRIS bits for the TX/RX pins.
If the chip supports open-drain mode then you just need to setup the TX pin...
Well the carpet is one thing. Even if you just walked the room and returned back to you chair (even worse if it has suspension), then you may well have charged enough to destroy the chips.
Re: How do you chose ADCIN channel in this case
Because I'm a potato-head. :D
