based on pollserial and PS2Keyboard.
|
||
|
|
Combined by Yotson, october 2011
|
||
|
|
|
||
|
|
ps2 keyboard library which uses the usart hardware for buffering individual bits into a byte before reading the byte by software.
|
||
|
|
Goal was to use a ps2 keyboard in combination with tv-out without image/timing corruption.
|
||
|
|
The interrupt driven version of ps2 keyboard messed with tv out image/timing.
|
||
|
|
|
||
|
|
Tested on atmega328. Not compatible with arduino mega/mega2560 as the XCKn pins are not broken out to header/pad.
