Usage
triggered = display.trigger.wait(timeout)
timeout
triggered
Remarks • This function will wait for the TRIG key on the front panel to be pressed. If the trigger key
was previously pressed and one or more trigger events were detected, this function will
return immediately.
• After waiting for a trigger with this function, the event detector will be automatically reset
and rearmed. This is true regardless of the number of events detected.
• Use the display.trigger.clear call to clear the trigger event detector.
Details See "Display
Also see display.trigger.clear
Waits up to five seconds for the TRIG key to be pressed:
Example
triggered = display.trigger.wait(5)
print(triggered)
Output:
true
The above output indicates that the TRIG key was pressed (trigger detected) before
the five second timeout expired.
display.waitkey
Function Captures the keycode value for the next key press.
Usage
key = display.waitkey()
Remarks • After sending this function,
wheel is pressed, or the wheel is turned to the right or left. After pressing a control or
turning the wheel, the keycode value for that key will be returned. The chart shown below
lists the keycode value for each front panel control. The controls are listed alphabetically.
• If the EXIT key is pressed while this function is waiting for a keypress, the script will not
be aborted.
• A typical use for this function is to prompt the user to press EXIT to abort the script or
press any other key to continue. If keycode value 75 is returned (EXIT key pressed), then
the exit() function can be called to abort the script. Sample code for this process is
provided in
