Brushless 27 Click

Brushless 27 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 example demonstrates the use of the Brushless 27 Click board by driving the motor in both directions at different speeds.

Example Libraries

• MikroSDK.Board
• MikroSDK.Log
• Click.Brushless27

Example Key Functions

• brushless27_cfg_setup Config Object Initialization function.

void brushless27_cfg_setup ( brushless27_cfg_t *cfg );

• brushless27_init Initialization function.

err_t brushless27_init ( brushless27_t *ctx, brushless27_cfg_t *cfg );

• brushless27_default_cfg Click Default Configuration function.

err_t brushless27_default_cfg ( brushless27_t *ctx );

• brushless27_set_pins Brushless 27 set pins function.

err_t brushless27_set_pins ( brushless27_t *ctx, uint8_t set_mask, uint8_t clr_mask );

• brushless27_set_trap_com_state Brushless 27 set trapezoidal com state function.

err_t brushless27_set_trap_com_state ( brushless27_t *ctx, uint8_t state );

• brushless27_drive_motor Brushless 27 drive motor function.

err_t brushless27_drive_motor ( brushless27_t *ctx, uint8_t dir, uint8_t speed, uint32_t time_ms );

Application Init

Initializes the driver and performs the Click default configuration.

void application_init ( void ) 
{
    log_cfg_t log_cfg;  /**< Logger config object. */
    brushless27_cfg_t brushless27_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.
    brushless27_cfg_setup( &brushless27_cfg );
    BRUSHLESS27_MAP_MIKROBUS( brushless27_cfg, MIKROBUS_1 );
    if ( I2C_MASTER_ERROR == brushless27_init( &brushless27, &brushless27_cfg ) ) 
    {
        log_error( &logger, " Communication init." );
        for ( ; ; );
    }
    
    if ( BRUSHLESS27_ERROR == brushless27_default_cfg ( &brushless27 ) )
    {
        log_error( &logger, " Default configuration." );
        for ( ; ; );
    }
    
    log_info( &logger, " Application Task " );
}

Application Task

Drives the motor in both directions and changes the motor speed approximately every 2 seconds. The driving direction and speed will be displayed on the USB UART.

void application_task ( void ) 
{
    log_printf ( &logger, "\r\n Driving motor clockwise \r\n" );
    for ( uint8_t speed = BRUSHLESS27_SPEED_MIN; speed <= BRUSHLESS27_SPEED_MAX; speed += 20 )
    {
        log_printf ( &logger, " Speed gain: %u\r\n", ( uint16_t ) speed );
        if ( BRUSHLESS27_OK != brushless27_drive_motor ( &brushless27, BRUSHLESS27_DIR_CW, speed, 2000 ) )
        {
            log_error ( &logger, " Drive motor " );
        }
    }
    Delay_ms ( 1000 );
    
    log_printf ( &logger, "\r\n Driving motor counter-clockwise \r\n" );
    for ( uint8_t speed = BRUSHLESS27_SPEED_MIN; speed <= BRUSHLESS27_SPEED_MAX; speed += 20 )
    {
        log_printf ( &logger, " Speed gain: %u\r\n", ( uint16_t ) speed );
        if ( BRUSHLESS27_OK != brushless27_drive_motor ( &brushless27, BRUSHLESS27_DIR_CCW, speed, 2000 ) )
        {
            log_error ( &logger, " Drive motor " );
        }
    }
    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.
