Click library

  • Author : MikroE Team
  • Date : Dec 2019.
  • Type : I2C type

Software Support

We provide a library for the Accel12 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 form compilers IDE(recommended way), or downloaded from our LibStock, or found on mikroE github account.

Library Description

This library contains API for Accel12 Click driver.

Standard key functions :

  • Config Object Initialization function.

    void accel12_cfg_setup ( accel12_cfg_t *cfg );

  • Initialization function.

    ACCEL12_RETVAL accel12_init ( accel12_t ctx, accel12_cfg_t cfg );

  • Click Default Configuration function.

    void accel12_default_cfg ( accel12_t *ctx );

Example key functions :

  • Functions for configuration one register

    void accel12_configuration ( accel12_t *ctx, uint8_t reg, uint8_t data_in );

  • Functions for read one Accel axis data

    int16_t accel12_get_one_axis ( accel12_t *ctx, uint8_t axis );

  • Functions for read Accel axis data

    void accel12_get_axis_data ( accel12_t ctx, int16_t x_axis, int16_t y_axis, int16_t z_axis);

Examples Description

This application allows acceleration measurement in three perpendicular axes.

The demo application is composed of two sections :

Application Init

Initialization driver init and configuration Accel measuremen and Tap detection interrupt


void application_init ( void )
{
    log_cfg_t log_cfg;
    accel12_cfg_t cfg;
    uint8_t temp;

    /** 
     * 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.

    accel12_cfg_setup( &cfg );
    ACCEL12_MAP_MIKROBUS( cfg, MIKROBUS_1 );
    accel12_init( &accel12, &cfg );

    accel12_default_cfg( &accel12 );

    log_printf( &logger, "--- Start measurement --- \r\n" );
}

Application Task

Reads the acceleration data in 3 axis and detects the tap on the axes. All data logs on the USBUART every 1.5sec.


void application_task ( void )
{
    int16_t X_Axis;
    int16_t Y_Axis;
    int16_t Z_Axis;
    uint8_t tap;

    /* Accelerometer measurement */
    accel12_get_axis_data( &accel12, &X_Axis, &Y_Axis, &Z_Axis );

    log_printf( &logger, " X axis : %d \r\n", X_Axis );

    log_printf( &logger, " Y axis : %d \r\n", Y_Axis );

    log_printf( &logger, " Z axis : %d \r\n", Z_Axis );

    /* TAP interrupt */
    tap = accel12_get_tap_detection( &accel12 );
    switch ( tap )
    {
        case 1:
        {
            log_printf( &logger, " X positive \r\n" );
            break;
        }
        case 2:
        {
            log_printf( &logger, " Y positive \r\n" );
            break;
        }
        case 3:
        {
            log_printf( &logger, " Z positive \r\n" );
            break;
        }
        case 4:
        {
            log_printf( &logger, " X negative \r\n" );
            break;
        }
        case 5:
        {
            log_printf( &logger, " Y negative \r\n" );
            break;
        }
        case 6:
        {
            log_printf( &logger, " Z negative \r\n" );
            break;
        }
    }
    log_printf( &logger, " -------------------------------- \r\n" );
    Delay_ms ( 1000 );
    Delay_ms ( 500 );
} 

The full application code, and ready to use projects can be installed directly form compilers IDE(recommneded) or found on LibStock page or mikroE GitHub accaunt.

Other mikroE Libraries used in the example:

  • MikroSDK.Board
  • MikroSDK.Log
  • Click.Accel12

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. The terminal available in all Mikroelektronika compilers, or any other terminal application of your choice, can be used to read the message.
