Series 2600A System SourceMeter® Instruments Reference Manual
Section 11: Display Operations
Capturing key-press codes
A history of the key code for the last pressed front panel key is maintained by the Series 2600A.
When the instrument is powered-on (or when transitioning from local to remote), the key code is
set to
0
(
display.KEY_NONE)
.
When a front panel key is pressed, the key code value for that key can be captured and returned.
There are two functions associated with the capture of key-press codes:
display.getlastkey
and
display.waitkey
.
display.getlastkey
The
display.getlastkey
function is used to immediately return the key code for the last pressed
key:
key = display.getlastkey()
print(key)
The above code will return the key code value (see
). Keep in mind that a value of
0
(
display.KEY_NONE
) indicates that the key code history had been cleared.
