Accel 30 Click is a compact add-on board that contains an acceleration sensor. This board features the MC3635, an ultra-low power, low-noise, integrated digital output 3-axis accelerometer from MEMSIC. The MC3635 allows selectable full-scale acceleration measurements in ranges of ±2g, ±4g, ±8g, ±12g, or ±16g in three axes with a configurable host interface that supports both SPI and I2C serial communication. It also supports high-resolution, low-power operating modes and interrupt feature for various events allowing maximum flexibility to meet multiple use case needs.

Click library

  • Author : Nenad Filipovic
  • Date : Feb 2023.
  • Type : I2C/SPI type

Software Support

We provide a library for the Accel 30 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 Accel 30 Click driver.

Standard key functions :

  • accel30_cfg_setup Config Object Initialization function.

    void accel30_cfg_setup ( accel30_cfg_t *cfg );
  • accel30_init Initialization function.

    err_t accel30_init ( accel30_t *ctx, accel30_cfg_t *cfg );
  • accel30_default_cfg Click Default Configuration function.

    err_t accel30_default_cfg ( accel30_t *ctx );

Example key functions :

  • accel30_get_axis Accel 30 get accel data function.

    err_t accel30_get_axis ( accel30_t *ctx, accel30_axis_t *acc_axis );
  • accel30_set_resolution_ctrl Accel 30 set resolution control function.

    err_t accel30_set_resolution_ctrl ( accel30_t *ctx, accel30_resolution_t resolution );
  • accel30_set_mode Accel 30 set operating mode function.

    err_t accel30_set_mode ( accel30_t *ctx, accel30_op_mode_t mode );

Example Description

This library contains API for Accel 30 Click driver. The library initializes and defines the I2C or SPI bus drivers to write and read data from registers. The library also includes a function for reading X-axis, Y-axis, and Z-axis data.

The demo application is composed of two sections :

Application Init

The initialization of I2C or 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. */
    accel30_cfg_t accel30_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.
    accel30_cfg_setup( &accel30_cfg );
    ACCEL30_MAP_MIKROBUS( accel30_cfg, MIKROBUS_1 );
    err_t init_flag = accel30_init( &accel30, &accel30_cfg );
    if ( ( I2C_MASTER_ERROR == init_flag ) || ( SPI_MASTER_ERROR == init_flag ) )
    {
        log_error( &logger, " Communication init." );
        for ( ; ; );
    }

    if ( ACCEL30_ERROR == accel30_default_cfg ( &accel30 ) )
    {
        log_error( &logger, " Default configuration." );
        for ( ; ; );
    }

    log_info( &logger, " Application Task " );
    log_printf( &logger, "------------------------\r\n" );
    log_printf( &logger, "       Accel Data       \r\n" );
    log_printf( &logger, "------------------------\r\n" );
    Delay_ms ( 100 ); 
}

Application Task

This example demonstrates the use of the Accel 30 Click board™. Measures and displays acceleration data for X-axis, Y-axis, and Z-axis. Results are being sent to the UART Terminal, where you can track their changes.

void application_task ( void )
{
    static accel30_axis_t axis;
    if ( ACCEL30_OK == accel30_get_axis( &accel30, &axis ) )
    {
        log_printf( &logger, "\tX : %d \r\n\tY : %d \r\n\tZ : %d \r\n", axis.x, axis.y, axis.z );
        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.

Other Mikroe Libraries used in the example:

  • MikroSDK.Board
  • MikroSDK.Log
  • Click.Accel30

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.
