-Empeg, Ltd's Empeg MP3 Car Audio Player

-The initial design is to go in your car, but you can use it at home, on a
-boat... almost anywhere. The principle is to store CD-quality music using
-MPEG technology onto a hard disk in the unit, and use the power of the
-embedded computer to serve up the music you want.
-
-For more details, see:

-Not a lot here yet :-)
-
-The Kenwood KCA-R6A remote control generates a sequence like the following:
-
-Go low for approx 16T (Around 9000us)
-Go high for approx 8T (Around 4000us)
-Go low for less than 2T (Around 750us)
-
-For each of the 32 bits
- Go high for more than 2T (Around 1500us) == 1
- Go high for less than T (Around 400us) == 0
- Go low for less than 2T (Around 750us)
-
-Rather than repeat a signal when the button is held down certain buttons
-generate the following code to indicate repetition.
-
-Go low for approx 16T
-Go high for approx 4T
-Go low for less than 2T
-
-(By removing the <2T from the start of the sequence and placing at the end
- it can be considered a stop bit but I found it easier to deal with it at
- the start).
-
-The 32 bits are encoded as XxYy where x and y are the actual data values
-while X and Y are the logical inverses of the associated data values. Using
-LSB first yields sensible codes for the numbers.
-
-All codes are of the form b9xx
-
-The numeric keys generate the code 0x where x is the number pressed.
