Working on my first project involving any degree of code, and also my first github post; I'm looking to use this as way to insert strings with a single button press (for example, game server commands).
Using "kbdLayout.write('This is a test!')" for example causes it to insert that string when the trinket boots, and subsequently locks up on the next button press.

Using Mu serial monitor I see:

main.py output:
Traceback (most recent call last):
File "main.py", line 44, in
File "miniKbdButtons.py", line 53, in update
File "main.py", line 28, in buttonDownCallback
File "adafruit_hid/keyboard.py", line 100, in press

File "adafruit_hid/keycode.py", line 311, in modifier_bit
TypeError: unsupported types for le: 'int', 'NoneType'

I'm not really sure how to approach this, any help would be appreciated.
