Instructions for use

Dependence

• RT-Thread 4.0.0+
• Sensor component
• IIC/SPI driver: mlx90392 devices use IIC for data communication, and need system IIC driver support;

Get the package

To use the MLX90392 software package, you need to select it in the RT-Thread package management. The specific path is as follows:

RT-Thread online packages  --->
  peripheral libraries and drivers  --->
    sensors drivers  --->
      mlx90392: Universal 3-axis sensor driver package,support: magnetometer.
              Version (latest)  --->
        [*]   Enable mlx90392 mag

Enable MLX90392 mag: Configure to turn on the Magnetometer function

Version: software package version selection

Using packages

The initialization function of MLX90392 software package is as follows:

int rt_hw_mlx90392_init(const char *name, struct rt_sensor_config *cfg);

This function needs to be called by the user. The main functions of the function are:

• Device configuration and initialization (configure interface devices and interrupt pins according to the incoming configuration information);
• Register the corresponding sensor device and complete the registration of the MLX90392 device;

Initialization example

#include "sensor_melexis_mlx90392.h"

int rt_hw_mlx90392_port(void)
{
    struct rt_sensor_config cfg;
    
    cfg.intf.dev_name = "i2c1";
    cfg.intf.user_data = (void *)MLX90392_ADDR_DEFAULT;
    cfg.irq_pin.pin = RT_PIN_NONE;

    rt_hw_mlx90392_init("mlx", &cfg);
    return 0;
}
INIT_APP_EXPORT(rt_hw_mlx90392_port);
