Click library

  • Author : Mihajlo Djordjevic
  • Date : Dec 2019.
  • Type : I2C/SPI type

Software Support

We provide a library for the Accel3 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 Accel3 Click driver.

Standard key functions :

  • Config Object Initialization function.

    void accel3_cfg_setup ( accel3_cfg_t *cfg );

  • Initialization function.

    ACCEL3_RETVAL accel3_init ( accel3_t ctx, accel3_cfg_t cfg );

  • Click Default Configuration function.

    void accel3_default_cfg ( accel3_t *ctx );

Example key functions :

  • This function select communication mode and executes start initialization.

    void accel3_default_cfg ( accel3_t ctx, accel3_cfg_t cfg );

  • This function reads Accel data ( X, Y and Z axis ) from the desired Accel registers of the H3LIS331DL module.

    void accel3_read_data ( accel3_t ctx, accel3_data_t accel3_data );

Examples Description

This is an example which demonstrates the usage of Accel 3 Click board.

The demo application is composed of two sections :

Application Init

Application Init performs Logger and Click initialization.


void application_init ( void )
{
    log_cfg_t log_cfg;
    accel3_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_printf( &logger, "--------------------------\r\n\n" );
    log_printf( &logger, "     Application  Init\r\n" );
    Delay_ms ( 100 );

    //  Click initialization.

    accel3_cfg_setup( &cfg );
    ACCEL3_MAP_MIKROBUS( cfg, MIKROBUS_1 );
    accel3_init( &accel3, &cfg );

    log_printf( &logger, "--------------------------\r\n\n" );
    log_printf( &logger, " -----  Accel 3 Click  -----\r\n" );
    log_printf( &logger, "--------------------------\r\n\n" );
    Delay_ms ( 1000 );

    accel3_default_cfg ( &accel3, &cfg );
    Delay_ms ( 100 );

    log_printf( &logger, " -- Initialization  done. --\r\n" );
    log_printf( &logger, "--------------------------\r\n\n" );
    Delay_ms ( 1000 );
}

Application Task

Measured coordinates (X,Y,Z) are being sent to the UART where you can track their changes. All data logs on USB UART for every 1 sec.


void application_task ( void )
{
    accel3_read_data( &accel3, &accel3_data );
    Delay_ms ( 100 );

    log_printf( &logger, "        Accelerometer       \r\n" );
    log_printf( &logger, "----------------------------\r\n" );
    log_printf( &logger, "        X = %d \r\n", accel3_data.x );
    log_printf( &logger, "        Y = %d \r\n", accel3_data.y );
    log_printf( &logger, "        Z = %d \r\n", accel3_data.z );
    log_printf( &logger, "----------------------------\r\n" );

    Delay_ms ( 1000 );
}  

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.Accel3

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.
