Brushless 10 Click

Brushless 10 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.

• Date : Mar 2024.
• Type : PWM type

Software Support

Example Description

This example demonstrates the use of the Brushless 10 Click board by driving the motor at different speeds.

Example Libraries

• MikroSDK.Board
• MikroSDK.Log
• Click.Brushless10

Example Key Functions

• brushless10_cfg_setup Config Object Initialization function.

void brushless10_cfg_setup ( brushless10_cfg_t *cfg );

• brushless10_init Initialization function.

err_t brushless10_init ( brushless10_t *ctx, brushless10_cfg_t *cfg );

• brushless10_default_cfg Click Default Configuration function.

err_t brushless10_default_cfg ( brushless10_t *ctx );

• brushless10_set_duty_cycle This function sets the PWM duty cycle in percentages ( Range[ 0..1 ] ).

err_t brushless10_set_duty_cycle ( brushless10_t *ctx, float duty_cycle );

• brushless10_pull_brake This function pulls brake by setting the BRAKE pin to high logic state.

void brushless10_pull_brake ( brushless10_t *ctx );

• brushless10_release_brake This function releases brake by setting the BRAKE pin to low logic state.

void brushless10_release_brake ( brushless10_t *ctx );

Application Init

Initializes the driver and performs the Click default configuration.

void application_init ( void )
{
    log_cfg_t log_cfg;  /**< Logger config object. */
    brushless10_cfg_t brushless10_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.
    brushless10_cfg_setup( &brushless10_cfg );
    BRUSHLESS10_MAP_MIKROBUS( brushless10_cfg, MIKROBUS_1 );
    if ( BRUSHLESS10_OK != brushless10_init( &brushless10, &brushless10_cfg ) )
    {
        log_error( &logger, " Communication init." );
        for ( ; ; );
    }
    
    if ( BRUSHLESS10_OK != brushless10_default_cfg ( &brushless10 ) )
    {
        log_error( &logger, " Default configuration." );
        for ( ; ; );
    }
    
    log_info( &logger, " Application Task " );
}

Application Task

Controls the motor speed by changing the PWM duty cycle every 2 seconds. The duty cycle ranges from 20% to 100%. Each step will be logged on the USB UART where you can track the program flow.

void application_task ( void )
{
    static int8_t duty_cnt = 2;
    static int8_t duty_inc = 1;
    float duty = duty_cnt / 10.0;
    
    brushless10_set_duty_cycle ( &brushless10, duty );
    log_printf( &logger, "> Duty: %d%%\r\n", ( uint16_t )( duty_cnt * 10 ) );
    
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );

    duty_cnt += duty_inc;
    if ( duty_cnt > 10 ) 
    {        
        duty_cnt = 9;
        duty_inc = -1;
    }
    else if ( duty_cnt < 2 ) 
    {
        duty_cnt = 2;
        duty_inc = 1;
        log_printf( &logger, " Pull brake\r\n" );
        brushless10_pull_brake ( &brushless10 );
        Delay_ms ( 1000 );
        Delay_ms ( 1000 );
        Delay_ms ( 1000 );
        log_printf( &logger, " Release brake\r\n" );
        brushless10_release_brake ( &brushless10 );
        Delay_ms ( 1000 );
    }
}

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.
