<h2>JMRI: USB Input Control</h2>
|
|
<strong>Note: This feature relies on a library from outside JMRI that is no
|
|
longer being maintained.
|
|
It is known to not work on Apple Silicon Macs.
|
|
It <u>will</u> stop working on other computer types at some point in the future.
|

<p>

<a href="TreeFrame.jpg"><img src="TreeFrame.jpg" class="floatRight" height="132" width="325"
|
|
alt="usb info"></a> The USB Input Control window lets you connect JMRI sensors and memories
|
|
to USB input devices on your computer. For example, you could have a JMRI sensor go ACTIVE
|
|
when when you type a key or press a joystick button. You can then use <a href=
|
|
"../../../../../html/tools/Routes.shtml">Routes</a> and <a href=
|
|
"../../../../../html/tools/Logix.shtml">Logix</a> to use that USB input to control your
|
|
layout.
|
|
<p>On the left side of the window is a tree displaying the available USB controllers and
|
|
components within them. Depending on details of your computer, this tree might be completely
|
|
populated when the window opens, or you might have to change the inputs (e.g. click a button)
|
|
to have it show up. Devices that are plugged in after the program starts may or may not
|
|
appear, depending on the specifics of your computer setup.</p>
|
|
|
|
<p>When you select a single component in the left-hand tree display, the right side pane will
|
|
show you the details of that component and it's current value.</p>
|
|
|
|
<p>Below that is an area for configuring the program to drive a JMRI <a href=
|
|
"../../../../../html/tools/Sensors.shtml">Sensor</a> and/or <a href=
|
|
"../../../../../html/tools/Memories.shtml">Memory</a> from the USB input. You can enter a
|
|
Sensor name in the top text field, and then check the "Copy to JMRI Sensor" box. When the
|
|
input goes On (for a digital input), or has a value greater than zero (for an analog input),
|
|
the Sensor will be set to ACTIVE, and it will otherwise be set to INACTIVE. You can watch
|
|
this work in the <a href="../../../jmrit/beantable/SensorTable.shtml">Sensor Table</a>.</p>
|
|
|
|
<p>Note that you can't edit the sensor name while the box is checked; you have to uncheck the
|
|
box so the Sensor stops following the USB input before changing to a new Sensor Name.</p>
