Remote control audi radio

audi radio (concert in my case) remote control protocol spec:
5V LOGIC idle state is HIGH (5V)

start bit:
 9ms LOW
4.55ms HIGH

 logic 1:
~600us LOW ~1700us HIGH

logic 0:
~600us LOW ~600us HIGH

stop bit:
~600us LOW

I use arduino duemilanove as logic analyzer, 10kHz sampling. OLS in version 0.9.7 already has arduino as input option, so no need for copying config files to plugins directory, actualy it's not working with this files.

I have MFSW without telephone option, so I read codes just for radio:

UP:       0x41E8D02F
DOWN: 0x41E850AF
LEFT:   0x41E840BF
RIGHT: 0x41E8C03F
VOL+:  0x41E8807F
VOL-:    0x41E800FF

code is always 0x41 0xE8 X 0xFF-X

after this i made simple arduino code to test all combination 0x00-0xFF with LCD sheel.

Emulator code is on github.
