TSP-Link
accessibility
This function can be accessed from a remote TSP-Link node.
Usage
key = display.waitkey()
key
The key code.
Remarks
• After sending this function, script execution will hold up until a front panel key or the wheel is
pressed, or the wheel is turned. After pressing a control or turning the wheel, the key code value
for that key will be returned. The chart shown below lists the key code value for each front panel
control. The controls are listed alphabetically.
• If the
EXIT
key is pressed while this function is waiting for a keystroke, 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 key code 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
in
.
• The above chart lists the numeric key code values for the front panel controls. The key code
value identifiers are listed in the documentation for
(for example,
display.KEY_RUN
is the identifier for the
RUN
key).
