24Protocol
25--------
26NEWS keyboard protocol is a usual asynchronous serial communication. You can receive data from the keyboard easily with UART of micro controller.
27
28- TTL level
29- 9600bps
30- 1-start bit
31- 8-data bit
32- non-parity
33- 1-stop bit.
34
35Its scan code is one byte consists of 1-bit release(break) flag at MSB and 7-bit code.
36For example 0x29 is sent when 'a' key is pressed and 0xA9 when released.
