==== Description: ====
ddcci.py is a simple Python script to send DDC/CI commands
to a computer monitor which supports it (DDC/CI means
Display Data Channel Command Interface).  E.g. it allows
to change the brightness or contrast.
It is using Linux-specific ioctls for I2C access.

The script uses Python's ctypes and fcntl modules to
do direct I2C_RDWR ioctls, so the only prerequisite
is a non-obsolete version of Python.
The traditional tool http://ddccontrol.sourceforge.net/
has a lot of legacy and is slow because it reads the
monitor's EDID and DDC/CI capabilities on each invocation.

However, I wanted something which can be bound to a keyboard hotkey
to control the monitor brightness, similar to laptops.
Thus it needed to be fast.  It doesn't do sanity checks but just fires
off a command on the I2C (DDC) bus device you are pointing it at.



==== Other Comments: ====
I wrote it a year ago and use it since then.
Seems to work stable at least for the simple
"change monitor brightness" use-case.
