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.
|
||||
|
||||

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.

prepare_write: called by the generic write path in VM to set up a write
|

request for a page. This indicates to the address space that
|

the given range of bytes is about to be written. The
|

address_space should check that the write will be able to

complete, by allocating space if necessary and doing any other

internal housekeeping. If the write will update parts of

any basic-blocks on storage, then those blocks should be

pre-read (if they haven't been read already) so that the

updated blocks can be written out properly.

Note: the page _must not_ be marked uptodate in this function
