Hi all,
Seems I was a little hasty with the latest patch. Today I had a look at
building the serial drivers to try out the remote control and the
piezo. After about 1/2 of reading and 1/2 testing I had something
working! This is why I really like Linux!
Anyhow I've just checked into CVS the code to get the serial ports
working.
/dev/ttyS0 is the remote control. if you type "stty -F /dev/ttyS0 raw"
and then "cat /dev/ttyS0" and then press a button on the remote control
you should see output.
The data appears as so:
0xff 0xfd 0xf1 0x00
and repeats until you release the key
when you get
0xff 0xfd 0xf0 0x00
the 0xf1 part varies on the key pressed.
0xf1 -> play/pause
0xf2 -> volume up
0xf3 -> volume down
0xf4 -> fast foward
0xf5 -> rewind
You can't write to this this serial port and expect anything good to
come from it.
/dev/ttyS1 is connected to the piezo.
dd if=/dev/zero of=/dev/ttyS0 count=10 bs=1
should produce some noise.
if=/dev/urandom should produce a different noise.
stty -F /dev/ttyS1 speed 19200
will also change the noise.
Now does anyone know of a portable serial keyboard that works with only
a TX line? :)
enjoy,
bern.
