How to toggle something like flood from a pendant with one button.

(Or how I learned to quit worrying and love the bomb)

This is so simple it's not funny.

Add the following to your postgui.hal file

 <b>loadrt toggle count=1</b>
 <b>addf toggle.0 servo-thread</b>

 <b># Flood Coolant control with one button</b>
 <b>net flood-toggle toggle.0.in &lt;= pyvcp.flood-button # or the input of your choice</b>
 <b>net flood-control toggle.0.out =&gt; pyvcp.led-09 # or the output of your choice</b>

Can it get any easier?

 Enjoy
