DMX Summary
Idea
- Set the UART to 250Kilobaud, 9 data bits, one stop bit
- attach an interrupt for a framing error. This indicates reception of the extra long DMX break character.
- Start receiving data. If the 9th bit is a one, a valid dmx value has been received. Increment the address pointer and continue
- Add example code
