Usage
keyCode
= display.getlastkey()
keyCode
A returned value that represents the last front-panel key pressed. See
Details
for
more information.
Details
A history of the key code for the last pressed front-panel key is maintained by the instrument. When the
instrument is turned on, or when it is transitioning from local to remote operation, the key code is set to 0
(
display.KEY_NONE
).
Pressing the
EXIT (LOCAL)
key normally aborts a script. To use this function with the EXIT (LOCAL) key,
display.locallockout
must be used.
The table below lists the
keyCode
value for each front-panel action.

NOTE
When using this function, use built-in constants such as
display.KEY_RIGHT
(rather than the
numeric value of
103
). This will allow for better forward compatibility with firmware revisions.
The OUTPUT ON/OFF control cannot be tracked by this function.
Example
key = display.getlastkey()
print(key)
On the front panel, press the
MENU
key and
then send the code to the left. This retrieves the
key code for the last pressed key.
Output:
6.01
