Overview
The QMC5883L is a multi-chip three-axis magnetic sensor. The QMC5883L is based on our state-of-the-art, high resolution, magneto-resistive technology licensed from Honeywell AMR technology. Along with custom-designed 16-bit ADC ASIC, it offers the advantages of low noise, high accuracy, low power consumption, offset cancellation and temperature compensation. QMC5883L enables 1° to 2° compass heading accuracy. The I²C serial bus allows for easy interface.

Default I2C interface 7 bit device address: 0x0D
User Guide
It is the best choice to develop embedded drivers with embedded rust. Because the driver can be used with MCU like ESP32, also used with ARM64 Linux Application, for example raspberry pi directly.
You can download the QMC5883L rust driver with git, also add your rust project with cargo – cargo add qmc5883l.
The examples as below use the first one.
