Python Barrier/Input-Leap Client

This is a Python Barrier Client that can run on CPython, CircuitPython, and MicroPython. The Python script can either use native HID Mouse/Keyboard or a CH9329 via serial. Below, I will describe the different use cases. The CH9329 Actor only has a vertical wheel as it does not implement a horizontal wheel. The HID Actor implements both vertical and horizontal wheels.

Windows/Linux/Mac

Only Windows was tested, but it should work on all PC environments.

• ACTOR_TYPE=HID: Uses the pyinput library for native keyboard/mouse. On Windows, the script must be run as an Administrator, as any window that is elevated will give keyboard/mouse control.
• ACTOR_TYPE=CH9329: Uses serial connected to CH9329. See docs for correct wiring and configuration. In the script, modify the SERIAL_PORT variable.

CircuitPython

Rename PY_Barrier.py to code.py. Copy code.py and boot.py to the root. All other libraries should be copied to the lib directory.

• ACTOR_TYPE=HID: Uses native HID USB. Tested on ESP32-S3 and Pi_Pico_W. ESP32-S3 requires the latest version (9.0 Absolute Newest >= PR9134) as it fixes USB HID lag issues. Other boards that support HID should also work. Click "Available on these boards" on the following link: USB HID CircuitPython Documentation
• ACTOR_TYPE=CH9329: Uses serial connected to CH9329. In the script, modify the CP_TX_PIN and CP_RX_PIN variables.

MicroPython

Rename PY_Barrier.py to code.py. Copy code.py and boot.py to the root. All other libraries should be copied to the lib directory.

• ACTOR_TYPE=HID: Uses native HID USB. At the time of writing it only on rp2 and samd boards. Only tested on Pi_Pico_W. Requires MicroPython version >= 1.23-preview. There is an MP_USB_INSTALL.py script to install the required imports, which is only required to run once. Refer to (micropython/micropython-lib#558) and (micropython/micropython#9497).
• ACTOR_TYPE=CH9329: Uses serial connected to CH9329. In the script, modify the MP_TX_PIN and MP_RX_PIN variables.
