## Specs:
* 250 kHz clock
* 250000 bits / s
* 4µs / bit
* idle line = high (transmitter/master drives line high)
## Pinout
1 0 GND
2 - B
3 + A
## Protocol
* paket format
* break
* mark (MAB)
* 2-512 frames
* frame 0 = start code = 0x00
* frame N = channel N = 0-255
* 1 start bit, 8 data bits, 2 stop bits, no parity
* mark (MTBF)
* mark (MTAP)
* break
* syncs start of DMX packet
* >= 22 low bits (88 µs)
* up to 1s
* recommended 25 - 30 low bits
* mark after break (MAB)
* immediately follows the break
* high mark of > 2 bits (8µs)
* up to 1s
* recommended 3 high bits
* (channel frames)
* first frame is start code (SC)
* data value = 0x00 signifies dimmer data
* 11 bits / frame
* 1 low bit (start bit)
* 8 data bits (0-255)
* 2 high bits (stop bits)
* mark time between frames (MTBF)
* idle time between frames; line kept high
* can be as short as desired
* between 1 and 512 sequential frames
* mark time between packets (MTBP)
* after the last frame's stop bits
* same as MTBF
* idle time between packets; line kept high
* can be as short as desired
