This is my first post here, so I'll try not to make a total fool of myself. Summing up, I plan to construct a throttle quadrant for my heavy metal flight sim sessions.
It will comprise six potentiometers, and six buttons, for the functionality of twin throttles with dual thrust reversers ( triggered by momentary on switches ), along with stab trim, rudder trim, speed-brakes, and flaps.
If all goes well with the metal work, I also intend to add dual TOGA buttons, and dual Autothrust Disengage buttons, with each pair run through OR gates.
After a long internet search, I found a schematic that is close in functionality to what I seek, and which I hope to modify to suit my configuration. Here is the link to the schematic I located :
http://www.flightsim.com/main/howto/mind.htm
I held out reasonable hope that this project could be a success, until I took one look at the 38 pages of program code that was needed to get the joystick in the above link USB readable, at which point the wind definitely dropped out of the sails for me.
As an engineering undergraduate back when dinasaurs roamed the earth, I dabbled with 8085 assembly language, but that shallow knowledge was of no help at all as I tried to make head or tail of the code used by the author of the project in the above link.
I am writing here to see if there is anyone who might be aware of pre-written code packages that could be modified by a bone-head like me, and used to interface my planned throttle quadrant with USB protocol. I have enclosed the slightly modified version of the schematic I would like to use, in case that might help narrow down the options that would work for this idea.
The non-inverting opamp amplifiers I included in my schematic adaptation are there because the 100K linear single turn pots on all the levers will only get about 60 degrees of travel from the lever articulations, and I want to be sure that a full 0 to 5 volt output is produced from each pot. Finally, I intend to use an ATMEga8 chip, which has identical pinouts to the one shown in the schematic.
