16 bit values 16 bit values are usually sent MSB first, or as course/fine where course = channel, fine = channel+1

We’ve designed lots of DMX equipment over the years.  Here’s our very simple guide:   Set the UART port up as 250k baud, 1 start bit, 2 stop bits, no parity bit. 250k baud means each bit is sent at 4uS intervals.  There are 11 bits sent for each byte: 4uS * 11 = 44uS […]
