Inclinometer 3 Click

Inclinometer 3 Click is a compact add-on board for precise tilt and leveling measurement applications. This board features the SCL3400-D01, a two-axis inclinometer sensor from Murata, leveraging advanced capacitive 3D-MEMS technology. It features a high-performance mixed-signal ASIC with a flexible SPI digital interface housed in a robust 12-pin pre-molded casing, ensuring long-term reliability and performance.

Click library

• Author : Nenad Filipovic
• Date : Dec 2023.
• Type : SPI type

Software Support

We provide a library for the Inclinometer 3 Click as well as a demo application (example), developed using MikroElektronika compilers. The demo can run on all the main MikroElektronika development boards.

Package can be downloaded/installed directly from NECTO Studio Package Manager(recommended way), downloaded from our LibStock™ or found on Mikroe github account.

Library Description

This library contains API for Inclinometer 3 Click driver.

Standard key functions :

• inclinometer3_cfg_setup Config Object Initialization function.

  void inclinometer3_cfg_setup ( inclinometer3_cfg_t *cfg );

• inclinometer3_init Initialization function.

  err_t inclinometer3_init ( inclinometer3_t *ctx, inclinometer3_cfg_t *cfg );

• inclinometer3_default_cfg Click Default Configuration function.

  err_t inclinometer3_default_cfg ( inclinometer3_t *ctx );

Example key functions :

• inclinometer3_get_axes This function reads the accelerometer sensor axes data by using SPI serial interface.

  err_t inclinometer3_get_axes ( inclinometer3_t *ctx, float *x_axes, float *y_axes );

• inclinometer3_get_temperature This function reads the temperature measurement data by using SPI serial interface.

  err_t inclinometer3_get_temperature ( inclinometer3_t *ctx, float *temperature );

Example Description

This library contains API for the Inclinometer 3 Click driver. The library initializes and defines the SPI drivers to write and read data from registers, as well as the default configuration for the reading accelerator and temperature data.

The demo application is composed of two sections :

Application Init

The initialization of the SPI module, log UART, and additional pins. After the driver init, the app executes a default configuration.

void application_init ( void )
{
    log_cfg_t log_cfg;  /**< Logger config object. */
    inclinometer3_cfg_t inclinometer3_cfg;  /**< Click config object. */

    /** 
     * Logger initialization.
     * Default baud rate: 115200
     * Default log level: LOG_LEVEL_DEBUG
     * @note If USB_UART_RX and USB_UART_TX 
     * are defined as HAL_PIN_NC, you will 
     * need to define them manually for log to work. 
     * See @b LOG_MAP_USB_UART macro definition for detailed explanation.
     */
    LOG_MAP_USB_UART( log_cfg );
    log_init( &logger, &log_cfg );
    log_info( &logger, " Application Init " );

    // Click initialization.
    inclinometer3_cfg_setup( &inclinometer3_cfg );
    INCLINOMETER3_MAP_MIKROBUS( inclinometer3_cfg, MIKROBUS_1 );
    if ( SPI_MASTER_ERROR == inclinometer3_init( &inclinometer3, &inclinometer3_cfg ) )
    {
        log_error( &logger, " Communication init." );
        for ( ; ; );
    }

    if ( INCLINOMETER3_ERROR == inclinometer3_default_cfg ( &inclinometer3 ) )
    {
        log_error( &logger, " Default configuration." );
        for ( ; ; );
    }

    log_info( &logger, " Application Task " );
    log_printf( &logger, " ________________________ \r\n" );
}

Application Task

This example demonstrates the use of the Inclinometer 3 Click board. Measures and displays acceleration data for the XY-axis [mg] and temperature [degree Celsius] data. Results are being sent to the UART Terminal, where you can track their changes.

void application_task ( void )
{
    float temperature = 0, x_axes = 0, y_axes = 0;
    if ( ( INCLINOMETER3_OK == inclinometer3_get_temperature( &inclinometer3, &temperature ) ) && 
         ( INCLINOMETER3_OK == inclinometer3_get_axes( &inclinometer3, &x_axes, &y_axes ) ) )
    {
        log_printf( &logger, " Accel X: %.2f mg\r\n", x_axes );
        log_printf( &logger, " Accel Y: %.2f mg\r\n\r\n", y_axes );
        log_printf( &logger, " Temperature : %.2f degC\r\n", temperature );
        log_printf( &logger, " ________________________ \r\n" );
        Delay_ms ( 1000 );
    }
}

The full application code, and ready to use projects can be installed directly from NECTO Studio Package Manager(recommended way), downloaded from our LibStock™ or found on Mikroe github account.

• MikroSDK.Board
• MikroSDK.Log
• Click.Inclinometer3

Additional notes and informations

Depending on the development board you are using, you may need USB UART Click, USB UART 2 Click or RS232 Click to connect to your PC, for development systems with no UART to USB interface available on the board. UART terminal is available in all MikroElektronika compilers.
