Section 14: Display Operations Series 2600 System SourceMeter® Instruments Reference Manual
When a front panel key is pressed, the keycode 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 keycode for the last pressed
key:
key = display.getlastkey()
print(key)
The above code will return the keycode value (see Table 14-4). Keep in mind that a value of 0
(display.KEY_NONE) indicates that the keycode history had been cleared.
