View Full Version : Throttle and Reverser on same pot

03-07-2009, 10:19 PM
Hi Fellow cockpit builders,

I have used the search function and cannot get an exact answer to my question and was hoping someone could assist.

I have bought a DIY throttle from SIMPARTS and i am trying to callibrate the reversers which are on the same pot as the throttle.

I have specified the low value as -4096 in my FS2Phidget config file, so that is no problem. The issue i have is I cannot seem to define an IDLE point on the pot, which means that when i am in the IDLE position on the throttles i am already applying 5% thrust. Applying reverser thrust works a treat and puts the pot in the -3000 FS range.

When i place the throttles to idle, my POT reading is 300.

Is there a way to tell FS2Phidget to map pot readings 300-1000 to FS values of 0 and 16,384 and then pot values between 0-300 to -4096 - 0?

Or is there another way to solve this problem apart from using a seperate pot for reversers.

Thank you kindly.

Did you try with FSUIPC axis calibration you can specify this option.

Hi Gerry,

Thanks for the tip.

For anyone else interested in getting this to work in the same way, I have done the following.

In FS2Phidgets i write to the following values 3BB2 - Quadrant axis 1 and 3BBA - Quadrant axis 2, which are hidden values in FSUIPC to write to AXIS values, since phidget cards will not register as Joysticks in windows. Then i set an FS range of 0-127 for the pot inputs in my fs2phidgets config file. Once this is done i can then move my pot all the way from one side to another and the FS value moves from 0-127. I then configure the Axis Assignment in FSUIPC by moving my throttle lever. This then is automatically registers the movement in the Axis Assignment Tab of FSUIPC. Once this is registered I tell it to send these values to the Axis Throttle 1. Then under the Joystick Calibration under Engines and then Throttle 1, i can specify Reverse, Idle and Max which are just calibrated by moving the pot into the required position.

Hope this helps someone else.
