<h1>JMRI: Fast Clocks</h1>
|
|
|
|
<p>JMRI provides two kinds of Fast Clock capability:</p>
|
|
|
|
<ul>
|
|
<li>Internal - the computers clock provides the time information</li>
|
|
|
|
<li>External - the DCC system ( or an object on a Layout Control Bus ) provides the time
|
|
information</li>
|
|
</ul>
|
|
|
|
<p>This help page describes the overall structure.</p>
|
|
|
|
<p>There are two different parts to consider: A "Timebase" provides the basic time
|
|
information, while one or more displays show you what's going on.</p>
|
|
|
|
<h2>Fast Clock Timebase</h2>
|
|
|
|
<p>To create a Timebase, use PanelPro > Tools > Clocks > <a href=
|
|
"../../../package/jmri/jmrit/simpleclock/SimpleClockFrame.shtml">Set up Fast Clock...</a>
|
|
This gives you a window where you can:</p>
|
|
|
|
<ul>
|
|
<li>Set the time</li>
|
|
|
|
<li>Start and stop the clock</li>
|
|
|
|
<li>Set the rate at which the clock runs</li>
|
|
|
|
<li>Select the timebase source to control (typically, this is the internal computer
|
|
clock)</li>
|
|
</ul>
|
|
|
|
<h2>Fast Clock Display</h2>
|
|
|
|
<p>Once you have created a timebase by configuring it in that window, you can open clocks
|
|
that will display on your screen, all with an optional pause/run button.</p>
|
|
|
|
<p>All clocks can be resized by dragging the window edges</p>

<p>Panel clock - you can also embed a clock in a panel from the panel editor.<br>
|
|
Analog clocks can be embedded into Layout Editor panels (instead of a separate window)
|
|
via Panel Window > Options > Add > Add Fast Clock</p>
|
|

|
|
"Analog Clock in Layout Editor Panel"></a>
|
|
</li>
|
|
</ul>
|
|
|
|
<p>When a clock is running, JMRI creates an internal sensor and a memory variable that you
|
|
can use to control and access the clock. The ISCLOCKRUNNING sensor controls whether the clock
|
|
is running (ACTIVE) or stopped (INACTIVE). The IMCURRENTTIME memory contains the current
|
|
fast-clock time, and can be easily accessed from Logix and scripts.</p>
|
|
|
|
<p>Lights can be an easy way to set up Fast Clock Logic, see <a href=
|
|
"../../../package/jmri/jmrit/beantable/LightAddEdit.shtml#lightcontrolfastclock">Light
|
|
Controller - Fast Clock Follower</a>.</p>

<p>Happy timekeeping!</p>
