Project description

Introduction

Documentation Status Discord Build Status

CircuitPython driver for use with IR Receivers.

Examples of products to use this library with:

Dependencies

This driver depends on:

Please ensure all dependencies are available on the CircuitPython filesystem. This is easily achieved by downloading the Adafruit library and driver bundle.

Installing from PyPI

On supported GNU/Linux systems like the Raspberry Pi, you can install the driver locally from PyPI. To install for current user:

pip3 install adafruit-circuitpython-irremote

To install system-wide (this may be required in some cases):

sudo pip3 install adafruit-circuitpython-irremote

To install in a virtual environment in your current project:

mkdir project-name && cd project-name
python3 -m venv .env
source .env/bin/activate
pip3 install adafruit-circuitpython-irremote

Usage Example

# Circuit Playground Express Demo Code
# Adjust the pulseio 'board.PIN' if using something else
import pulseio
import board
import adafruit_irremote
pulsein = pulseio.PulseIn(board.REMOTEIN, maxlen=120, idle_state=True)
decoder = adafruit_irremote.GenericDecode()

# size must match what you are decoding! for NEC use 4
received_code = bytearray(4)

while True:
    pulses = decoder.read_pulses(pulsein)
    print("Heard", len(pulses), "Pulses:", pulses)
    try:
        code = decoder.decode_bits(pulses, debug=False)
        print("Decoded:", code)
    except adafruit_irremote.IRNECRepeatException:  # unusual short code!
        print("NEC repeat!")
    except adafruit_irremote.IRDecodeException as e:     # failed to decode
        print("Failed to decode: ", e.args)

    print("----------------------------")
