display.waitkey
The display.waitkey function captures the keycode value for the next key
press:
key = display.waitkey()
After sending the display.waitkey function, the script will pause and wait for the
operator to press a front panel key. For example, if the MEAS key is pressed, the
function will return the value 86, which is the keycode for that key. The keycode
values are listed in
Table14-3 .
Example: The following code will prompt the user to press the EXIT key to abort
the script, or any other key to continue it:
display.clear()
display.setcursor(1, 1)
display.settext("Press EXIT to Abort")
display.setcursor(2, 1)
display.settext("or any key to continue")
key = display.waitkey()
display.clear()
display.setcursor(1, 1)
if (key == 75) then
display.settext("Test Aborted")
exit()
else display.settext("Test Continuing")
end
The above code captures the key that is pressed by the operator. The keycode
value for the EXIT key is 75. If EXIT is pressed, the script aborts. If any other key
is pressed, the script will continue.
