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.

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.

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.
The page will be locked.
Note: the page _must not_ be marked uptodate in this function
(or anywhere else) unless it actually is uptodate right now. As
soon as a page is marked uptodate, it is possible for a concurrent
read(2) to copy it to userspace.
commit_write: If prepare_write succeeds, new data will be copied
into the page and then commit_write will be called. It will
typically update the size of the file (if appropriate) and
mark the inode as dirty, and do any other related housekeeping
operations. It should avoid returning an error if possible -
errors should have been handled by prepare_write.
write_begin: This is intended as a replacement for prepare_write. The
key differences being that:
- it returns a locked page (in *pagep) rather than being
given a pre locked page;
- it must be able to cope with short writes (where the
length passed to write_begin is greater than the number
of bytes copied into the page).
