There is only one file 'disp'. To send bytes (like chars to be displayed)
you send a series of unsigned base-10 values separated by spaces.
For example:
echo "hi there" | perl -e \
'$_=<STDIN>; while (/(.)/gc) { print ord($1)," "; }' \
> /proc/sys/dev/sensors/matorb*/disp
This is equivelent to doing:
echo "104 105 32 116 104 101 114 101" > /proc/sys/dev/sensors/matorb*/disp
I was going to create more files for doing things like clearing the screen,
but it is easier and probably better to do this in user-space. For example,
to clean the screen, you can do:
echo "254 88" > /proc/sys/dev/sensors/matorb*/disp
(As documented in the manual from Matrix-Orbital)
If the folks at Matrix-Orbital added device ID on a read (we talked about
this), then I will add an ID file to indicate that info.
TODO: finish detection. Right now it looks for a device at a particular
address and assumes it is a display.

* Made i2c-voodoo3.c compile with 2.0 kernels
It should also run without problem, but obviously I could not test it
Changes are in the memory mapping of PCI address space
* Removed several warning from i2c-voodoo3.c
It compiles now without any warnings, even with WARN=1
* Removed several warnings from matorb.c
It compiles now without any warnings, even with WARN=1
In the proces, I fixed one serious bug (assignment instead of comparison)
* Removed a warning from w83781d.c
It compiles now without any warnings, even with WARN=1
Hint: Once in a while, try to compile with WARN=1 and remove warnings. It
helps to find serious, hidden problems. Really!

is right now, it should clear the LCD screen. But, I discovered that
the display simply can't cope with I2C read commands - it completely
locks up *both* the data and the *clock* lines! (That's new.) So,
it kills the bus when probes or other reads are done to the device.
Matrix-Orbital has to fix this before we can get anything
usable working. :'(
