<div class="PlainText">I've pushed a 'beta' version of the vld-epics driver to github:<br>
<br>
<a href="https://github.com/JeffersonLab/vld-epics">https://github.com/JeffersonLab/vld-epics</a><br>
<br>
It has read/write support to the VLD parameters, but does not yet <br>
include 'automated' specific procedure support (bleaching, calibration <br>
pulse).<br>
<br>
I'm starting to code up that procedure support into the vld library <br>
(which has also been updated). We ought to talk about specifics for the <br>
bleaching / calibration pulse functionality and driver hooks to your UI.<br>
