	1	Sun to USB keyboard protocol converter
	2	======================================
	3
	4	TODO
	5	----
	6	AVR UART engine expect positive logic while Sun keyboard signal is inverted serial.
	7	To use AVR UART engine you need inverter in front of RX and TX pin.
	8	Otherwise you can software serial routine to communicate the keyboard.

	11	Hardware
	12	--------
	13	Target MCU is ATMega32u4 but other USB capable AVR will also work.
	14	You can use PJRC Teensy as dev board.

	47	And load the binary to MCU with your favorite programmer.
	48	If you use Teensy you can load with PJRC Teensy Loader tool.
