Cycle Timer

Connect time.n.start to halui.is-running to complete the cycle timer.

The pyVCP code to display it might be like:
<pyvcp>
	<hbox>
	<label>
		<text>"Cycle Time"</text>
		<font>("Helvetica",14)</font>	
	</label>
	<u32> 
    	<halpin>"time-hours"</halpin>
    	<font>("Helvetica",14)</font>
    	<format>"2d"</format>
	</u32>
	<label>
		<text>":"</text>
		<font>("Helvetica",14)</font>	
	</label>
	<u32> 
    	<halpin>"time-minutes"</halpin>
    	<font>("Helvetica",14)</font>
    	<format>"2d"</format>
	</u32>
	<label>
		<text>":"</text>
		<font>("Helvetica",14)</font>	
	</label>
	<u32> 
    	<halpin>"time-seconds"</halpin>
    	<font>("Helvetica",14)</font>
    	<format>"2d"</format>
	</u32>
	</hbox>
</pyvcp>

In your post-gui.hal file you might use the following to connect it up

 loadrt time
 addf time.0 servo-thread
 net cycle-timer time.0.start <= halui.program.is-running
 net cycle-seconds pyvcp.time-seconds <= time.0.seconds
 net cycle-minutes pyvcp.time-minutes <= time.0.minutes
 net cycle-hours pyvcp.time-hours <= time.0.hours
