TIME(9)

NAME

time - Time on in Hours, Minutes, Seconds

SYNOPSIS

loadrt time [count=N|names=name1[,name2...]]

DESCRIPTION

Time

When either the time.N.start or time.N.pause bits goes true the cycle timer resets and starts to time until time.N.start AND time.N.pause go false. When the time.N.pause bit goes true timing is paused until time.N.pause goes false. If you connect time.N.start to halui.program.is-running and leave time.N.pause unconnected the timer will reset during a pause. See the example connections below for more information.

Time returns the hours, minutes, and seconds that time.N.start is true.

Sample PyVCP code to display the hours:minutes:seconds.

<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 one of the following to connect this timer:

 For a new config:

 loadrt time
 addf time.0 servo-thread
 net cycle-timer time.0.start <= halui.program.is-running
 net cycle-timer-pause time.0.pause <= halui.program.is-paused
 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

 Previous to this version if you wanted the timer to continue running
 during a pause instead of resetting, you had to use a HAL NOT component
 to invert the halui.program.is-idle pin and connect to time.N.start as
 shown below:

 loadrt time
 loadrt not
 addf time.0 servo-thread
 addf not.0 servo-thread
 net prog-running not.0.in <= halui.program.is-idle
 net cycle-timer time.0.start <= not.0.out
 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

 For those who have this setup already, you can simply add a net connecting
 time.N.pause to halui.program.is-paused:

 net cycle-timer-pause time.0.pause <= halui.program.is-paused
