Vibro Motor 4 Click is a compact add-on board that makes an ideal solution for adding simple haptic feedback in any design. This board features the G1040003D, a coin-sized linear resonant actuator (LRA) that generates vibration/haptic feedback from Jinlong Machinery & Electronics, Inc. Driven by a flexible Haptic/Vibra driver, the DRV2605, G1040003D vibrates in the Z-axis, which is perpendicular to the face of the vibration motor. It draws a maximum of 170mA while producing the highest G force/vibration energy of 2 GRMS. This Click board™ makes an excellent choice for devices with limited battery capacity and for users who require crisp haptic feedback and low power consumption.

Click library

  • Author : Nenad Filipovic
  • Date : Aug 2021.
  • Type : I2C type

Software Support

We provide a library for the VibroMotor4 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 VibroMotor4 Click driver.

Standard key functions :

  • vibromotor4_cfg_setup Config Object Initialization function.

    void vibromotor4_cfg_setup ( vibromotor4_cfg_t *cfg );
  • vibromotor4_init Initialization function.

    err_t vibromotor4_init ( vibromotor4_t *ctx, vibromotor4_cfg_t *cfg );
  • vibromotor4_default_cfg Click Default Configuration function.

    err_t vibromotor4_default_cfg ( vibromotor4_t *ctx );

Example key functions :

  • vibromotor4_set_mode Vibro Motor 4 sets the desired mode function.

    err_t vibromotor4_set_mode ( vibromotor4_t *ctx, uint8_t mode_sel );
  • vibromotor4_set_duty_cycle Vibro Motor 4 sets PWM duty cycle.

    err_t vibromotor4_set_duty_cycle ( vibromotor4_t *ctx, float duty_cycle );
  • vibromotor4_pwm_start Vibro Motor 4 start PWM module.

    err_t vibromotor4_pwm_start ( vibromotor4_t *ctx );

Example Description

This library contains API for Vibro Motor 4 Click driver. The library initializes and defines the I2C bus drivers to write and read data from registers and PWM module.

The demo application is composed of two sections :

Application Init

The initialization of I2C and PWM module, log UART, and additional pins. After successful driver init, executes a default configuration and configures Vibro Motor 4 Click board™.


void application_init ( void )
{
    log_cfg_t log_cfg;                  /**< Logger config object. */
    vibromotor4_cfg_t vibromotor4_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.
    vibromotor4_cfg_setup( &vibromotor4_cfg );
    VIBROMOTOR4_MAP_MIKROBUS( vibromotor4_cfg, MIKROBUS_1 );
    err_t init_flag = vibromotor4_init( &vibromotor4, &vibromotor4_cfg );
    if ( I2C_MASTER_ERROR == init_flag )
    {
        log_error( &logger, " Application Init Error. " );
        log_info( &logger, " Please, run program again... " );

        for ( ; ; );
    }

    vibromotor4_enable( &vibromotor4, VIBROMOTOR4_PROPERTY_ENABLE );
    Delay_ms ( 100 );

    vibromotor4_soft_rst( &vibromotor4 );
    Delay_ms ( 100 );

    vibromotor4_default_cfg ( &vibromotor4 );
    Delay_ms ( 100 );

    vibromotor4_set_duty_cycle( &vibromotor4, 0.0 );
    Delay_ms ( 100 );

    vibromotor4_pwm_start( &vibromotor4 );
    Delay_ms ( 100 );

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

Application Task

This is an example that shows the use of Vibro Motor 4 Click board™. Changing duty cycle results in different vibrations. Results are being sent to the Usart Terminal where you can track their changes.


void application_task ( void )
{
    static int8_t duty_cnt = 0;
    static int8_t duty_inc = 1;
    float duty = duty_cnt / 10.0;

    vibromotor4_set_duty_cycle ( &vibromotor4, duty );
    log_printf( &logger, "> Duty: %d%%\r\n", ( uint16_t )( duty_cnt * 10 ) );

    Delay_ms ( 1000 );

    if ( 5 == 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.VibroMotor4

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.

Analog MUX 3 Click

0

Analog MUX 3 Click is a compact add-on board that switches one of the eight inputs to one output. This board features the ADG738, a CMOS analog matrix switch with a serially-controlled SPI interface from Analog Devices. In an active state, the ADG738 conducts equally well in both directions, making it suitable for multiplexing and demultiplexing applications. It can also be configured as a type of switch array where any, all, or none of eight switches may be closed any time. All channels exhibit ‘break-before-make switching action, preventing momentary shorting when switching channels. This Click board™ is suitable for a wide range of applications, from industrial and instrumentation to medical, consumer, communications, and automotive systems.
