pico_hid | USB HID Keyboard Emulator

This Python script emulates a USB keyboard using CircuitPython and the Adafruit HID library. It allows automated keystroke input, including typing full strings with customizable delays.

Features

• Emulates a USB keyboard
• Supports typing full strings with adjustable delays
• Supports special character inputs
• Provides a function to press arbitrary key combinations

Requirements

• A microcontroller board that supports USB HID (e.g., Raspberry Pi Pico, Adafruit Trinket M0, etc.)
• CircuitPython installed on the board
• adafruit_hid library installed

Installation

1. Install CircuitPython on your microcontroller board.
2. Download and copy the adafruit_hid library into the lib/ folder on your board.
3. Save the script as code.py on your microcontroller board.

Usage

Type a String

Use the type_string function to simulate typing a string.

from your_script_name import type_string

type_string("Hello, World!")

Press Key Combinations

Use the key function to press and release keys with a delay.

from adafruit_hid.keycode import Keycode
from your_script_name import key

key(Keycode.CONTROL, Keycode.C)  # Simulates Ctrl+C

Example Code

type_string("Hello, World!")
