Library Description

The library covers all the necessary functions to control Vibro Motor 3 Click board™. Library holds the drivers for writeing and reading, for enable/diasble the device, trigger the device, sets desired mode function, resets all register, for getting status, start or stop the motor, etc.

Key functions:

• void vibromotor3_set_mode ( uint8_t mode_sel ); - Function is used to apply the desired mode.
• void vibromotor3_start_motor ( uint8_t state ); - The function is used to start or stop the motor.
• void vibromotor3_set_lra_mode ( uint8_t state ); - The function is used to sets the device in LRA mode.

Examples description

The application is composed of three sections :

• System Initialization - Initializes I2C, GPIO and LOG structures, and sets CS and PWM pins as output ,and start to write log.
• Application Initialization - Initalizes I2C driver, PWM driver and configures Vibro Motor 3 Click board™.
• Application Task - This example shows the capabilities of the Vibro Motor 3 Click board™ by changeing duty cycle applied in order to get different vibrations.

void application_task ( )
{
    pwm_duty_cycle += 1000;
    mikrobus_logWrite( "Duty cycle applied: ", _LOG_TEXT );
    WordToStr( pwm_duty_cycle, log_txt );
    Ltrim( log_txt );
    mikrobus_logWrite( log_txt, _LOG_LINE );
    vibromotor3_pwm_set_duty( pwm_duty_cycle );
    if ( pwm_duty_cycle > pwm_max_duty )
    {
        pwm_duty_cycle = 0;
        vibromotor3_pwm_stop( );
        Delay_ms( 2000 );
        vibromotor3_pwm_start( );
    }
    Delay_ms( 100 );
}

Other mikroE Libraries used in the example:

• I2C
• UART
• PWM
• Conversions

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.
