Custom Throttle with Jynstruments
are powerful tools for
customizing JMRI Throttles. There's much more
on creating and customizing them on a separate page
. Here, we focus on using the customized
Jynstruments provided below are for controlling already assigned Throttles, the Throttle
pane you will control has to be set up before. Then it's only a matter of drag'n dropping a
folder on the Throttle Window toolbar.
Note that Throttle Window content is Jynstrumentable
too, so here we drop the Jynstruments on the toolbar itself, not on the window
USB device (USBThrottle.jyn)
There is a Jynstrument named USBThrottle.jyn to be dropped on a Throttle Window toolbar to get
control of that Window with a HID device (joypad, RailDriver ...). See the .py files for default button settings, and
Particularly you might want to define a "driver" file for your own device, start from
default.py, copy it, rename it with the name of the device as seen by JMRI without any space
or ".", then use the
JMRI Jinput USB Input Control window (accessible from Debug menu) to get your Components
names and value,
To browse through the currently assigned throttles for the controlled window, the pov right
and left buttons are used (the pov, also known as switch hat, is the four or eight
directions button on the left of the pad).
Speed is controlled by axis "x" which usually is found on the left stick.
Note that buttons 0 to 3 (or 1 to 4) are assigned to some speed presets, from idle (speed
0), to slow (speed 0,3), to cruise (speed 0,8), to max (speed 1). A double tap on the
button for speed 0 will send an emergency stop.
Direction is controlled by axis "z" which usually is found on right left stick
All remaining buttons are dedicated to functions (usually the one left on the side, under,
and in the middle of the gamepad)
Note that joypads buttons layout, and even sticks events
differ from one manufacturer to another, hence you should customize a driver.py for your own
This one will listen for DCC throttle events for a specific DCC address and forward them to the
current active throttle inside this JMRI throttle window.
Nintendo Wiimote (WiimoteThrottle.jyn)
There is a Jynstrument named WiimoteThrottle.jyn to be dropped on a Throttle Window toolbar
to get control of that Window with a Nintendo Wiimote device. See the .py file for
default button settings and set up
(some jars are to be downloaded and copied in JMRI lib
At the moment, none of the accelerometers of the Wiimote are used, hence it's only a kind of
deluxe remote as we only use the buttons. But it fits very well in one hand and once you know
the settings, you don't even have to look at it to use it.
To browse through the currently assigned throttles for the controlled window, the left and
right buttons are used.
Speed is controlled by buttons A (decelerate) and B (accelerate)
Note that buttons 1 and 2 are used for some speed presets, from idle (speed 0 - button 2
twice), to slow (speed 0,3 - button 2 once), to cruise (speed 0,8 - button 1 once), to max
(speed 1 - button 1 twice). Pressing buttons 1 and 2 will send an emergency stop and
vibrate the Wiimote.
Direction is controlled by buttons + and -.
Light (function 0) is controlled by Home button.
And as there is no more buttons available, no other function can be controlled by default,
but as this is a Jython script, feel free to customize, and if somebody is able to do
something with the accelerometers, you're very welcome!

iPhone and iPod Touch
There's a third-party application called WiThrottle
works with JMRI to let you control trains with your iPhone or iPod Touch.
You can also browse the JMRI webserver from Safari on
your iPhone or iPod Touch.
