Click library

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

Software Support

We provide a library for the Accel11 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 Accel11 Click driver.

Standard key functions :

  • Config Object Initialization function.

    void accel11_cfg_setup ( accel11_cfg_t *cfg );

  • Initialization function.

    ACCEL11_RETVAL accel11_init ( accel11_t ctx, accel11_cfg_t cfg );

  • Click Default Configuration function.

    void accel11_default_cfg ( accel11_t *ctx );

Example key functions :

  • This function reads accel axis.

    int16_t accel11_get_axis_data ( accel11_t *ctx, uint8_t axis );

  • This function test comunication.

    uint8_t accel11_test_comunication ( accel11_t *ctx );

  • This function for power on chip.

    void accel11_power_on_procedure ( accel11_t *ctx );

Examples Description

This demo application reads X / Y / Z axis acceleration data.

The demo application is composed of two sections :

Application Init

Initialization device.


void application_init ( void )
{
    uint8_t tmp;
    log_cfg_t log_cfg;
    accel11_cfg_t cfg;

    /** 
     * 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 ----\r\n" );

    //  Click initialization.

    accel11_cfg_setup( &cfg );
    ACCEL11_MAP_MIKROBUS( cfg, MIKROBUS_1 );
    accel11_init( &accel11, &cfg );

    tmp = accel11_test_comunication( &accel11 );
    if ( tmp == ACCEL11_TEST_COMUNICATION_OK )
    {
        log_printf( &logger, " Comunication OK !!!\r\n" );
    }
    else
    {
        log_printf( &logger, " Comunication ERROR !!!\r\n" );
        for ( ; ; );
    }
    accel11_default_cfg( &accel11 );
}

Application Task

Reads X / Y / Z axis acceleration data and it logs to USBUART every 1500ms.


void application_task ( void )
{
    int16_t x_axis;
    int16_t y_axis;
    int16_t z_axis;

    x_axis = accel11_get_axis_data( &accel11, ACCEL11_ACCEL_X_AXIS );
    log_printf( &logger, " X axis : %d\r\n", x_axis );

    y_axis = accel11_get_axis_data( &accel11, ACCEL11_ACCEL_Y_AXIS );
    log_printf( &logger, " Y axis : %d\r\n", y_axis );

    z_axis = accel11_get_axis_data( &accel11, ACCEL11_ACCEL_Z_AXIS );
    log_printf( &logger, " Z axis : %d\r\n", z_axis );

    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.Accel11

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.
