Yet another one - this time in Python. Should be easy to port, though.
Features:
- no dimming
- no stopping if backlight not lit
- badly adjusted timers
- reopening the file at every check
- able to set the right position even if device is nearly lying
- does not switch if on verge of two modes
...and the two latter things are what I like in it.
The timers are really bad - it takes up to 10 seconds to adjust (checking
position every 3 seconds, 1.5 second to make sure plus some unidentified delay).
