<h1>USING A MPG</h1>
|
|
<p>The WoodPecker interface allows for the use of an external Manual Pulse Generator (MPG) by checking the Use MPG checkbox
|
|
in the SETTINGS page.</p>
|
|
<p>A separate HAL file is used to define I/O pins that connect to the MPG and the <i>woodpecker_postgui.hal</i>
|
|
is used to make the connections to the WoodPecker HAL pins.</p>
|
|
<h2>AXIS SELECT</h2>
|
|
<p>Four HAL input pins are created to connect the MPG selected axis signals to the Jog joypad highlight segments to indicate
|
|
which axis is being jogged with the MPG. </p>
|
|
<h2>SCALE SELECT</h2>
|
|
<p>A HAL float input pin is created to allow the handler file to display the currently selected jog scale setting of the MPG.
|
|
Connections from the MPG to a mux4 HAL component are made in a <i>mpg.hal</i> file and the output of the mux4 is connected
|
|
to WoodPecker in order to display the currently selected MPG scale value.</p>
|
|
<h2>MPG DISABLE</h2>
|
|
<p>A HAL output pin is created to disable the MPG encoder if the Use MPG checkbox is unchecked. This will also hide the
|
|
MPG Scale display from the WoodPecker screen.</p>
