## Instructions for use

### Dependence

- RT-Thread 4.0.0+
- Sensor component
- SPI driver: mlx90382 devices use SPI for data communication, and need system SPI driver support;

### Get the package

To use the mlx90382 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  --->
      mlx90382: Universal 3D magnetic sensor driver package.
              Version (latest)  --->
```

**Version**: software package version selection

### Using packages

The initialization function of mlx90382 software package is as follows:

```
int rt_hw_mlx90382_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 mlx90382 device;

#### Initialization example

```
#include "sensor_melexis_mlx90382.h"

int rt_hw_mlx90382_port(void)
{
    struct rt_sensor_config cfg;

    cfg.intf.dev_name  = "spi10";

    rt_hw_mlx90382_init("mps", &cfg);

    return 0;
}
INIT_ENV_EXPORT(rt_hw_mlx90382_port);
```

```

* This function configures the hardware resources used in this example
* @param hspi: SPI handle pointer
* @retval None

{
  GPIO_InitTypeDef GPIO_InitStruct = {0};

  if(hspi->Instance==SPI1)
  {
  /* USER CODE BEGIN SPI1_MspInit 0 */

  /* USER CODE END SPI1_MspInit 0 */
    /* Peripheral clock enable */
    __HAL_RCC_SPI1_CLK_ENABLE();

    __HAL_RCC_GPIOA_CLK_ENABLE();
    /**SPI1 GPIO Configuration

    */
    GPIO_InitStruct.Pin = GPIO_PIN_5|GPIO_PIN_6|GPIO_PIN_7;
    GPIO_InitStruct.Mode = GPIO_MODE_AF_PP;
    GPIO_InitStruct.Pull = GPIO_NOPULL;
    GPIO_InitStruct.Speed = GPIO_SPEED_FREQ_VERY_HIGH;
    GPIO_InitStruct.Alternate = GPIO_AF5_SPI1;
    HAL_GPIO_Init(GPIOA, &GPIO_InitStruct);

  /* USER CODE BEGIN SPI1_MspInit 1 */

  /* USER CODE END SPI1_MspInit 1 */
  }

}

/**
* @brief SPI MSP De-Initialization
* This function freeze the hardware resources used in this example
* @param hspi: SPI handle pointer
* @retval None
*/

{
  if(hspi->Instance==SPI1)
  {
  /* USER CODE BEGIN SPI1_MspDeInit 0 */

  /* USER CODE END SPI1_MspDeInit 0 */
    /* Peripheral clock disable */
    __HAL_RCC_SPI1_CLK_DISABLE();

  /* USER CODE BEGIN SPI1_MspDeInit 1 */

  /* USER CODE END SPI1_MspDeInit 1 */
  }

}

// 自动初始化实现SPI设备挂载
int mlx90382_spi_device_init(void)
{
    __HAL_RCC_GPIOA_CLK_ENABLE();

    return rt_hw_spi_device_attach("spi1", "spi10", GPIOA, GPIO_PIN_8);    //EAF
}
INIT_DEVICE_EXPORT(mlx90382_spi_device_init);
```
