Brushless 2 Click

Brushless 2 Click demo application is developed using the NECTO Studio, ensuring compatibility with mikroSDK's open-source libraries and tools. Designed for plug-and-play implementation and testing, the demo is fully compatible with all development, starter, and mikromedia boards featuring a mikroBUS™ socket.

Click Library

  • Author : Nikola peric
  • Date : Mar 2022.
  • Type : PWM type

Software Support

Example Description

This application controlled speed motor.

Example Libraries

  • MikroSDK.Board
  • MikroSDK.Log
  • Click.Brushless2

Example Key Functions

  • brushless2_cfg_setup Config Object Initialization function.
void brushless2_cfg_setup ( brushless2_cfg_t *cfg );
  • brushless2_init Initialization function.
err_t brushless2_init ( brushless2_t *ctx, brushless2_cfg_t *cfg );
  • brushless2_counter_clockwise Set the direction of rotation in the counterclockwise direction function.
void brushless2_counter_clockwise( brushless2_t *ctx );
  • brushless2_clockwise Set the direction of rotation in the clockwise direction function.
void brushless2_clockwise( brushless2_t *ctx );
  • brushless2_get_interrupt_status Get Interrupt pin state function.
uint8_t brushless2_get_interrupt_status( brushless2_t *ctx );

Application Init

Initialization driver enable's - GPIO, PWM initialization

void application_init ( void )
{
    log_cfg_t log_cfg;
    brushless2_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_info( &logger, "---- Application Init ----" );

    //  Click initialization.

    brushless2_cfg_setup( &cfg );
    BRUSHLESS2_MAP_MIKROBUS( cfg, MIKROBUS_1 );
    brushless2_init( &brushless2, &cfg );
    
    log_printf( &logger, "---------------------- \r\n" );
    
    brushless2_set_duty_cycle ( &brushless2, 0.0 );
    brushless2_pwm_start ( &brushless2 );
    Delay_ms ( 500 );
    log_info( &logger, "---- Application Task ----" );
}

Application Task

This is a example which demonstrates the use of Brushless 2 Click board. Brushless 2 Click communicates with register via PWM interface. Results are being sent to the Usart Terminal where you can track their changes.

void application_task ( void )
{    
    static int8_t duty_cnt = 1;
    static int8_t duty_inc = 1;
    float duty = duty_cnt / 10.0;
    
    brushless2_set_duty_cycle ( &brushless2, duty );
    brushless2_clockwise ( &brushless2 );
    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;
}

Application Output

This Click board can be interfaced and monitored in two ways:

  • Application Output - Use the "Application Output" window in Debug mode for real-time data monitoring. Set it up properly by following this tutorial.
  • UART Terminal - Monitor data via the UART Terminal using a USB to UART converter. For detailed instructions, check out this tutorial.

Additional Notes and Information

The complete application code and a ready-to-use project are available through the NECTO Studio Package Manager for direct installation in the NECTO Studio. The application code can also be found on the MIKROE GitHub account.
