Can FPP output DMX to an I/O pin?

On either Pi or BBB?

Well TTL DMX at least - I realize I would still need a differential line driver.

David offers an excellent solution through a cap product over on Falcon Christmas.

Can I get one in South Africa in the next 72 hours?

Otherwise, back to the original question - I would like to output DMX directly to the UART on the Raspberry Pi and have it go out BCM 14 (or wherever).

The main challenge of course is that the Raspberry Pi's UART doesn't have a native setting for 250 kbps, but the guy below was able to do it, so was wondering if FPP provides something like this:

IMHO that question is best asked and answered over on the Falcon (FPP) forum.
