Actually - no fine tuning necessary for the aircraft configuration at all.
But of course there is some work to be done for the joystick configuration
file.
Since ELITE refused to publish the protocol they use, I decided to completely
replace the controller hardware in the devices and not do reverse engineer
their secrets. I also did not want to have any driver at all but to use the
HID joystick interface.
The new controller is built with ATMEL microcontroller. There is a free USB1.0
protocol stack available for ATMEL and development is easy with GCC and glibc
for ATMEL.
The cheapest controller is the ATTINY45 in a 8 pin DIL. It runs with internal
clock (no chrystal needed), just a few resitors, 2 Z-diodes and a few
capacitor make a 2-axis, 4 button HID joystick and interfaces the barebone
ELITE yoke for less than 5$.
For the ProPanel II (Yoke and power quadrant and roughly 45 switches), I use
the ATMEGA 8 and 4 16-port multiplexer. I added a few rotary encoder to
emulate the twister knobs of many instruments and drive the heading bug for
example. This is also done thru the HID joystick protocol.
If you are interested in the hardware interface, I can send you schematics and
the ATMEL firmware and the sourcecode.
Greetings, Torsten
