Serial ACE (Arbitrary Code Execution over serial interface)
Caution: This module allows unrestricted, arbitrary code execution on your KMK device. That includes potential exploits, such as keyloggers, and unvetted user code that may result in undesired behaviour and/or crashes. This feature is purely experimental in the sense that you probably neither want nor should use it in production. Advanced knowledge of python and the serial console is required, and we will not provide help or support in any way.
This module provides an API to run any valid python code on your keyboard and return the result of that code via an additional serial consol (not the one you use for the circuitpython debugger).
Enable the data serial in
Enable the module, just as any other module else:
from kmk.modules.serialace import SerialACE
Assume the data serial is on
Depending on your OS settings, it bay be necessary to explicitly set the serial
device to raw transmission, no echo:
stty -F /dev/ttyACM1 raw -echo
Get the List of Active Layers
$ echo "keyboard.active_layers" > /dev/ttyACM1
$ cat /dev/ttyACM1
"Tap" a Key
$ echo "exec('from kmk.keys import KC; keyboard.tap_key(KC.Y)')" > /dev/ttyACM1
