Introduction
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-irremoteTo install system-wide (this may be required in some cases):
sudo pip3 install adafruit-circuitpython-irremoteTo 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-irremoteUsage 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("----------------------------")Contributing
