Throttle Control Alternative for Phidgets

Hi Potroh,

All calibration data is saved in the dvatx.ini file.. under min= max= values..

Actually Ive just found a bug in the proggy where the trim wheel doesnt work correctly when the motorcard and interfacecard are plugged in together.. But Ive fixed that...

Ive also added the auto retraction of the spoiler/speedbrake once the plane has touched down and throttle is applied... Will update in the library soon.

:)

Cheers

Diego

Hello diegov, (I'm back from my vacation)

I have installed the new version but it does not work properly. Only with the calibration slider I can control the levers. Trimwheel does nothing.

The cockpit is from flightdecksolutions and I'm using project magenta.

PROJECTMAGENTA=1

For the throttle quadrant I have the advancedServo8 card and the Phidget Motor Card but not the Interface 8/8/8 card. Our interface with the throttle quadrant is the BU0836 card.

Another question about controlling a wiper DC motor of a Fiat Cinquecento with the High Current Motor card. Does the card have enough power with the phidgets adapter? The DC motor was already installed in the throttle quadrant.

V1.10 does not work (no throttle (only manual), spoiler and trimwheel)
V1.05 controls the throttle levers very good (but no spoiler and trimwheel control)

Michel,

Try this:

There are some bugs in v1.10.. i havent fully tested this new version, but let me know how it goes.

I dont have PM so i also didnt test that component on the latest builds.. If it doesnt work with PM please try with the default MCP and let me know. This new version also contains spoiler logic to move the handle back to down when you apply throttles on the ground. The Phidget HC cards requires seperate power to power the DC motor. The DC motor is isolated from the USB power.

There IS a way to control dc motors and have feedback.

There is a file in the download library by PDG737. He has built his own throttle using dc motors with feedback. You can find a video in the videolibrary with me flying his sim.

He is currently motorizing my real 200 throttle.

We are using a small pcb from Conrad. you connect a dc motor and a feedback pot to it, and the pcb is connected to a servo card. So in fact your computer thinks its driving a servo, but it is driving a dc motor. Clutch connected to the dc motor and you can push through the lever position. When released the lever will go back to the assigned position.

A schematic of his system can be found here:

This does mean you can not use a dc motors interface but have to use a servo card.

hi diego - thanks for the work on the AT -

I've been using FS2P to drive my throttles using a DC motor and a hacked HiTec servo - details are here - using this rig, one can use any DC motor upto 28VDC

details here: http://www.mycockpit.org/forums/showthread.php?t=14926


will try and post a video sometime soon

Hello all!

We have DC motors too and what we're trying to do now is to write a simple application that reads (via FSUIPC) actual levers position (read through the FS2Phidgets and 8/8/8 card), desired position (from another variable) and puts the difference to the third variable, which is linked (in FS2Phidgets) to the HC DC motor driver from Phidgets.

Now we have limited success due to the fact that real PID regulator is needed to be implemented.

What do you think about this way?

Thanks Stef!

This is great news...

(i did post something longer last night but it disappeared???)

Regards,

Nat

Diego,

I have a small problem with my throttle and hope you can help me a bit.

Asking, because my hardware throttle has a TOGA push-button, it only changes the toga state and unless N1 is ON and lights up the servos don't move in TOGA mode.
When using your prg to drive the servos, everything works fine, but pressing toga will not connect the servos unless I press the N1 button on my MCP.

So either somehow I need to invoke the N1 button to change state when TOGA is pushed, or even better would be to know which offset do you use to disconnect the servos and under what exact conditions.

thanks in advance
Potroh

Hi Potroh,

What are you using for the MCP? is it the default FSX MCP?

DVATX will power the servos for toga as long as the bit is set for offset 080C and the AT is armed, so if you are using the phidgets interface card you can configure the dvatx.ini file to use one of the digital sensor to set the offset 080C to a value of 1 and connect that to your hardware toga button to the phidget card, alternatively you will need to somehow get your toga button to set offset 080C to 1 through another mechanism

Let me know how you go.

Cheers

Diego

Hi Diego,

Thanks for your prompt answer.
Well, my case is a bit complicated, as I use Poject Magenta and CPFlight's MCP hardware.
Thus, offset 080C has little use for me, as PM's MCP is deliberately disables it by default.
PM is using its own offset for TOGA (050A bit 0) and ignores the default one.

I can of course write a small line in PMSystems to invoke 080C to be on, whenever my pushbutton
is pressed, but PM's MCP changes it back to 0 immediately.
DVATX is so nice and gives me such a smooth and nice movement for servos, that I truly love it, apart from this,
which actually forced me to ask about this problem.

If you can think of any solution for me, please help
regards
Potroh
