Brushless 24 Click

Brushless 24 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.

Example Description

This application is a schowcase of controlling speed of brushless motor using Brushless 24 Click.

Example Libraries

• MikroSDK.Board
• MikroSDK.Log
• Click.Brushless24

Example Key Functions

• brushless24_cfg_setup Config Object Initialization function.

void brushless24_cfg_setup ( brushless24_cfg_t *cfg );

• brushless24_init Initialization function.

err_t brushless24_init ( brushless24_t *ctx, brushless24_cfg_t *cfg );

• brushless24_default_cfg Click Default Configuration function.

err_t brushless24_default_cfg ( brushless24_t *ctx );

• brushless24_set_duty_cycle Brushless 24 sets PWM duty cycle.

err_t brushless24_set_duty_cycle ( brushless24_t *ctx, float duty_cycle );

• brushless24_pwm_start Brushless 24 start PWM module.

err_t brushless24_pwm_start ( brushless24_t *ctx );

• brushless24_get_int_state Brushless 24 get INT pin state.

uint8_t brushless24_get_int_state ( brushless24_t *ctx );

Application Init

Initialization of LOG, PWM module and additional pins.

void application_init ( void ) 
{
    log_cfg_t log_cfg;  /**< Logger config object. */
    brushless24_cfg_t brushless24_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.
    brushless24_cfg_setup( &brushless24_cfg );
    BRUSHLESS24_MAP_MIKROBUS( brushless24_cfg, MIKROBUS_POSITION_BRUSHLESS24 );
    if ( PWM_ERROR == brushless24_init( &brushless24, &brushless24_cfg ) )
    {
        log_error( &logger, " Communication init." );
        for ( ; ; );
    }
    
    if ( BRUSHLESS24_ERROR == brushless24_default_cfg ( &brushless24 ) )
    {
        log_error( &logger, " Default configuration." );
        for ( ; ; );
    }
    
    log_info( &logger, " Application Task " );
}

Application Task

In a span of second changes duty cycle from 0 to 100% which is changing speed of the motor.

void application_task ( void ) 
{
    static int8_t duty_cnt = 1;
    static int8_t duty_inc = 1;
    float duty = duty_cnt / 10.0;
    
    brushless24_set_duty_cycle ( &brushless24, duty );
    log_printf( &logger, "> Duty: %d%%\r\n", ( uint16_t )( duty_cnt * 10 ) );
    
    Delay_ms ( 1000 );
    
    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.
