Re: Throttle Control Alternative for Phidgets
I would think this is not possible. You need some sort of feedback mechanism so that the driving software knows where the motor shaft is positioned and that is not available in a straight DC motor (or AC for that matter). That is why either servos or stepping motors are required since the shaft rotation can be controlled accurately.
Another problem with DC motors is that they don't normally stop instantly, so it would be rather hard to position them accurately even if you could devise some feedback mechanism.
But I could be wrong

Re: Throttle Control Alternative for Phidgets
Hi Gents,
Nat, AFAIK Maurice is correct. For DC motors some sort of encoder device would be required to provide position information to the computer controlling the motor. You would need to use something like an optical encoder or i guess you could use a POT to feedback on the position of the throttles.
@Potroh, Your request should be fairly easy to implement. Ill get it done on the next release!
Cheers
Diego

Re: Throttle Control Alternative for Phidgets
Hi Guys,
I placed another version into the mycockpit file library. It is under phidgets.
Ive added the ability to specify the fsuipc offset reference for the throttle servos..
Also modified the trim wheel code to provide high and low rotation modes depending on the flap settings.. Thanks to Nat for the info
Also modified the code so trim wheel spin at intervals rather than countinously.
If you use sim-avionics like me then you can modify the INI file to detect A/T settings for the sim-avionics MCP.. Please read the readme.txt
Cheers
Diego

Re: Throttle Control Alternative for Phidgets
Diego,
The new version is great, works perfectly, many thanks.
Just one question: where do you save the calibration data?
regards
Potroh
