Click library

  • Author : Stefan Ilic
  • Date : Feb 2023.
  • Type : I2C type

Software Support

We provide a library for the Accel 25 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 25 Click driver.

Standard key functions :

  • accel25_cfg_setup Config Object Initialization function.

    void accel25_cfg_setup ( accel25_cfg_t *cfg );
  • accel25_init Initialization function.

    err_t accel25_init ( accel25_t *ctx, accel25_cfg_t *cfg );
  • accel25_default_cfg Click Default Configuration function.

    err_t accel25_default_cfg ( accel25_t *ctx );

Example key functions :

  • accel25_soft_reset Accel 25 soft reset function.

    err_t accel25_soft_reset ( accel25_t *ctx );
  • accel25_set_full_scale_range Accel 25 set full scale range function.

    err_t accel25_set_full_scale_range ( accel25_t *ctx, uint8_t fsr );
  • accel25_read_data Accel 25 read data function.

    err_t accel25_read_data ( accel25_t *ctx, accel25_data_t *data_out );

Example Description

This example demonstrates the use of Accel 25 Click board by reading and displaying accel data (X, Y, and Z axis) as well as temperature measurements on the USB UART.

The demo application is composed of two sections :

Application Init

Initializes the driver and performs the Click default configuration.


void application_init ( void ) 
{
    log_cfg_t log_cfg;  /**< Logger config object. */
    accel25_cfg_t accel25_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.
    accel25_cfg_setup( &accel25_cfg );
    ACCEL25_MAP_MIKROBUS( accel25_cfg, MIKROBUS_1 );
    if ( I2C_MASTER_ERROR == accel25_init( &accel25, &accel25_cfg ) ) 
    {
        log_error( &logger, " Communication init." );
        for ( ; ; );
    }

    if ( ACCEL25_ERROR == accel25_default_cfg ( &accel25 ) )
    {
        log_error( &logger, " Default configuration." );
        for ( ; ; );
    }

    log_info( &logger, " Application Task " );
}

Application Task

Reads and displays the accel data (X, Y, and Z axis) as well as temperature measurements on the USB UART every 100ms approximately.

void application_task ( void ) 
{
    accel25_data_t meas_data;
    // Wait for data ready indication
    if ( ACCEL25_PIN_STATE_LOW == accel25_get_int_pin ( &accel25 ) );
    {
        if ( ACCEL25_OK == accel25_read_data ( &accel25, &meas_data ) )
        {
            log_printf( &logger, " X: %.3f g\r\n", meas_data.x );
            log_printf( &logger, " Y: %.3f g\r\n", meas_data.y );
            log_printf( &logger, " Z: %.3f g\r\n", meas_data.z );
            log_printf( &logger, " Temperature: %.2f degC\r\n", meas_data.temperature );
        }
    Delay_ms ( 100 );
    }
}

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.Accel25

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.
