Micropython-IR
MicroPython library for sniffing and replaying infrared remote signals on Pyboard.
Overview
Micropython-IR is a MicroPython library that enables infrared remote control signal analysis and transmission on Pyboard devices. It provides tools for capturing raw infrared signals from remotes and replaying them through GPIO pins, making it useful for home automation, device control, and hardware prototyping projects.
Key Features
- Signal Sniffing — Reads and decodes infrared signals from remote controls via GPIO pins with microsecond precision.
- Signal Replay — Transmits captured or custom binary-encoded infrared signals through specified GPIO pins.
- Binary Analysis — Analyzes raw signal data to identify digital 0 and 1 patterns based on frequency detection.
- GPIO Flexibility — Works with any GPIO pin on Pyboard for both input (sniffing) and output (replay) operations.
Philosophy
The project focuses on providing a lightweight, hardware-level interface for infrared communication, prioritizing direct GPIO control and binary signal manipulation for embedded applications.
