Framing error if I disable transmitter after shift register is empty?

[Demon]

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....

I've misunderstood/misinterpreted the data sheet before. Seriously, I read the EUSART section and my eyes gloss over when they start making distinctions between half-duplex, full-duplex, synchronous, asynchronous...)

..If the chip supports open-drain mode then you just need to setup the TX pin to enable it at startup (ODCONC.6 = 1).
There's no need to set and clear it, and you won't need to enable/disable TXEN anymore either...

Something like..?

TRISC.7=1
ODCONC.6 = 1

Loop:
TX, RX, rinse repeat

I would have thought you need to reset ODCONC.6 to "standard push/pull"...? (Possible example of not always understanding what the datasheet "means").

...If your pic has PPS you'll probably need to set that up too to assign the pin to the UART TXD function.
PPS output functions aren't typically enabled by default.

Yes, I figured that much. There's just so many peripherals available (coming from a guy that started with a 16F628).


EDIT: I just rechecked the EUSART section (starts at page 543), and they never mention ODCON (last occurence is at page 233).

The datasheet says very little about ODCON:
