ibuddy 1.0.1

Control the MSN i-Buddy USB figure from Python

ibuddy

Control your MSN i-Buddy USB figure from Python.

The i-Buddy is a small USB HID figure with a head LED (7 colors), heart light, flapping wings, and a swiveling torso. This library gives you full control over all of it.

pip install ibuddy

Windows only - The i-Buddy uses Windows HID APIs for communication.

Quick Start

from ibuddy import IBuddyDevice

with IBuddyDevice() as buddy:
    buddy.demo()

That's it. Plug in your i-Buddy, run the code, and watch it go.

Usage

Connecting

The library uses a context manager so the device is always properly reset when you're done:

from ibuddy import IBuddyDevice

with IBuddyDevice() as buddy:
    buddy.head_color("red")
    buddy.flap(3)
# Automatically resets and closes

Head LED

Set the head to one of 7 named colors:

buddy.head_color("red")         # Hold for 0.3s (default)
buddy.head_color("blue", 1.0)   # Hold for 1 second
buddy.head_color("green", 0)    # Set and return immediately

# Available colors: red, green, blue, cyan, magenta, yellow, white

Or set raw RGB bits directly:

buddy.set_head_color(1, 0, 0)  # Red (r=1, g=0, b=0)
buddy._send()                   # Send the command

Heart LED

buddy.heart(True)         # Turn on for 0.3s
buddy.heart(False)        # Turn off for 0.3s
buddy.heart(True, 1.0)    # Stay on for 1 second
buddy.heart(False, 0)     # Turn off immediately

buddy.heartbeat(times=5, delay=0.2)  # Blink 5 times

Wings

buddy.flap(times=3, delay=0.15)  # Flap 3 times (default)
buddy.flap(10, 0.1)              # Flap 10 times, faster

Torso Swivel

buddy.wiggle(times=3, delay=0.5)  # Wiggle left/right 3 times
buddy.wiggle(5, 0.3)              # Faster wiggle

Combos

buddy.rainbow(times=2)     # Cycle all 7 colors twice
buddy.celebrate()           # Wiggle + flap + heartbeat + rainbow
buddy.demo()                # Full demo of every feature

Low-Level Control

buddy.set_wing(True)        # Wings up
buddy.set_wing(False)       # Wings down
buddy.set_swivel("left")    # Swivel left
buddy.set_swivel("right")   # Swivel right
buddy.set_heart(True)       # Heart on
buddy.reset()               # Everything off

After setting state manually, call buddy._send() to push it to the device.
