Click library

  • Author : Stefan Ilic
  • Date : Jul 2021.
  • Type : I2C type

Software Support

We provide a library for the VibroMotor3 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 VibroMotor3 Click driver.

Standard key functions :

  • vibromotor3_cfg_setup Config Object Initialization function.

    void vibromotor3_cfg_setup ( vibromotor3_cfg_t *cfg );
  • vibromotor3_init Initialization function.

    err_t vibromotor3_init ( vibromotor3_t *ctx, vibromotor3_cfg_t *cfg );
  • vibromotor3_default_cfg Vibro Motor 3 default configuration function.

    err_t vibromotor3_default_cfg ( vibromotor3_t *ctx );

Example key functions :

  • vibromotor3_set_duty_cycle Vibro Motor 3 sets PWM duty cycle.

    err_t vibromotor3_set_duty_cycle ( vibromotor3_t *ctx, float duty_cycle );
  • vibromotor3_enable Enable the device function

    void vibromotor3_enable ( vibromotor3_t *ctx, uint8_t state );
  • vibromotor3_write_byte Generic write the byte of data function

    void vibromotor3_write_byte ( vibromotor3_t *ctx, uint8_t reg, uint8_t wr_data );

Example Description

This example shows the capabilities of the Vibro Motor 3 Click board

The demo application is composed of two sections :

Application Init

Initalizes I2C driver, PWM driver and configures Vibro Motor 3 Click board.


void application_init ( void ) {
    log_cfg_t log_cfg;  /**< Logger config object. */
    vibromotor3_cfg_t vibromotor3_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.
    vibromotor3_cfg_setup( &vibromotor3_cfg );
    VIBROMOTOR3_MAP_MIKROBUS( vibromotor3_cfg, MIKROBUS_1 );
    err_t init_flag = vibromotor3_init( &vibromotor3, &vibromotor3_cfg );
    if ( I2C_MASTER_ERROR == init_flag || PWM_ERROR == init_flag ) {
        log_error( &logger, " Application Init Error. " );
        log_info( &logger, " Please, run program again... " );

        for ( ; ; );
    }
    vibromotor3_enable( &vibromotor3, VIBROMOTOR3_PROPERTY_ENABLE );
    Delay_ms ( 100 );

    vibromotor3_soft_rst( &vibromotor3 );
    Delay_ms ( 100 );

    vibromotor3_default_cfg( &vibromotor3 );
    Delay_ms ( 100 );

    vibromotor3_set_duty_cycle( &vibromotor3, 0.0 );
    vibromotor3_pwm_start( &vibromotor3 );
    Delay_ms ( 100 );

    log_info( &logger, " Application Task " );
    Delay_ms ( 100 );
}

Application Task

Changing duty cycle applied in order to get different vibrations.


void application_task ( void ) {
    static int8_t duty_cnt = 1;
    static int8_t duty_inc = 1;
    float duty = duty_cnt / 10.0;

    vibromotor3_set_duty_cycle ( &vibromotor3, duty );
    log_printf( &logger, "> Duty: %d%%\r\n", ( uint16_t )( duty_cnt * 10 ) );

    Delay_ms ( 500 );

    if ( 10 == duty_cnt ) {
        duty_inc = -1;
    } else if ( 0 == duty_cnt ) {
        duty_inc = 1;
    }
    duty_cnt += duty_inc;
}

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.VibroMotor3

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.
