display.getlastkey()
The
display.getlastkey()
function immediately returns the key code for the last pressed key.
The following programming example illustrates how to display the last key pressed:
key = display.getlastkey()
print(key)
The above code will return the key code value (see the following table). Remember that a value of
0
(
display.KEY_NONE
) indicates that the key code history had been cleared.

display.waitkey()
The
display.waitkey()
function captures the key code value for the next key press:
key
= display.waitkey()
After sending the
display.waitkey()
function, the script pauses and waits for the operator to
press a front-panel key. For example, if the MENU key is pressed, the function returns the value
68
,
which is the key code for that key. The key code values are the same as listed in
(on page 11-129).
