The Directinput Standard; Commands; The Arduino 'Serial' Monitor - IRIS Dragonfly VR IDL-20004 Setup And User's Manual

In standalone (default) mode the yoke will not vary forces with airspeed or provide ground bumps/stall
buffeting etc. These effects can be achieved by having your simulation software produce corresponding
force feedback commands using the standard USB protocols. When a program like a flight sim or add-
on sends commands to the Yoke, it will stop its default spring and damper effects until the flight sim or
add-on is closed.
Not all simulators send effects by default. If your yoke feels the same after you start your flight
simulator, check the simulator's force feedback or control loading settings. You may require an add-on.

3.2. The DirectInput Standard

The DragonflyVR™ Flight Yoke System complies with standard protocols that provide force feedback
commands to USB devices. Therefore, any program that would cause any other USB device to move will
have a similar effect on your yoke. Popular plugins like FS Force or XPForce use this method and will
detect your yoke. They send effects based on the simulator environment.

4. COMMANDS

4.1. The Arduino 'Serial' Monitor

Thanks to the great work done by the Arduino and Teensyduino teams, the DragonflyVR™ was
programmed using the user-friendly Arduino environment (with the Teensyduino add-on).
As such, it's relatively easy to listen to messages coming from the yoke and to send commands.
Here's how you can hear what the yoke is telling you, and send it serial commands:
1. Install the Arduino IDE: http://arduino.cc/en/main/software. Install version 1.6.5 for best results
(https://www.arduino.cc/en/Main/OldSoftwareReleases#previous)
2. Install the Teensyduino add-on:
3. With the flight yoke system connected, open the Arduino environment and select the following
settings:
a. Select the Teensy used in the yoke:
Tools -> Board -> Teensy 3.2 / 3.1
b. Select the communication protocol (serial):
Tools -> USB Type -> Serial
c. Select the serial COM port for the yoke. It will be the last one in the list (highest COM
port number) if it was the last device you installed on your computer.
Tools -> Port -> [select the serial COM port]
4. Open the Serial Monitor by pressing the button in the top right corner, or by pressing
[Ctrl]+[Shift]+[M]
5. Say hi!
