|
||||
|
||||
This converter allows NEWS keyboard to be connected to modern PC via USB. It works with NWP-5461 and NWP-411A.
|
||||
|
||||
How DIP switches work is unknown and you may need to turn all switches off with this converter.
|
||||
|
||||
Limitations:
|
||||
- Speaker/Buzzer is not supported.
|
||||
- LEDs on NWP-5461 is not supported.

Protocol
|
||||
--------
|
||||
NEWS keyboard protocol is a usual asynchronous serial communication. You can receive data from the keyboard easily with UART of micro controller.
|
||||
|
||||
- TTL level
|
||||
- 9600bps
|
||||
- 1-start bit
|
||||
- 8-data bit
|
||||
- non-parity
|
||||
- 1-stop bit.
|
||||
|
||||
Its scan code is one byte consists of 1-bit release(break) flag at MSB and 7-bit code.
|
||||
For example 0x29 is sent when 'a' key is pressed and 0xA9 when released.
|
||||
|
||||
MSB LSB
|
||||
7 6 5 4 3 2 1 0 bit
|
||||

|
||||
| +-+-+-+-+-+-+-- scan code(00-7F)
