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...
Re: SOLVED - PIC seems to RESET unless I add a PAUSE in Mainloop
What is the duration of this reset, if it is reset?
Ioannis Today, 09:54You may add a PAUSE 1000 at the beggining of the program and see if this duration is increased. This will confirm that PIC is indeed reseting....
