7Semi-HMC6343-3-Axis-Digital-Compass-Module-with-Tilt-Compensation-I2C-Arduino-Library

This Arduino library provides support for the 7Semi-HMC6343 3-axis digital compass sensor over I2C. It allows reading of tilt-compensated heading, pitch, and roll, and includes features like magnetic variation correction and low-power control.

Hardware Required

• HMC6343 sensor module

• Arduino-compatible board

• I2C connection (SDA, SCL)

Getting Started

1. Library Installation

  - Download or clone the repository.

  - Copy the files `7semi_hmc6343.cpp` and `7semi_hmc6343.h` into a folder named `7semi_HMC6343` under your Arduino `libraries/` directory.

  - Restart the Arduino IDE.

2. Wiring

    | HMC6343 Pin | Arduino Pin |
