Brushless 3 Click

Brushless 3 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 : MikroE Team
• Date : Jan 2020.
• Type : I2C type

Software Support

Example Description

This Click has three-phase sensorless motor driver and with an external power supply it drives a brushless DC motor.

Example Libraries

• MikroSDK.Board
• MikroSDK.Log
• Click.Brushless3

Example Key Functions

• brushless3_cfg_setup Config Object Initialization function.

void brushless3_cfg_setup ( brushless3_cfg_t *cfg );

• brushless3_init Initialization function.

err_t brushless3_init ( brushless3_t *ctx, brushless3_cfg_t *cfg );

• brushless3_default_cfg Click Default Configuration function.

err_t brushless3_default_cfg ( brushless3_t *ctx );

• brushless3_set_speed Set speed function

err_t brushless3_set_speed ( brushless3_t *ctx, uint16_t motor_speed_hz );

• brushless3_get_speed Get speed function

err_t brushless3_get_speed ( brushless3_t *ctx, float *speed );

• brushless3_forward_direction Set the direction of rotation in the forward direction function

void brushless3_forward_direction ( brushless3_t *ctx );

Application Init

Initialization driver enable's - I2C, set default parameter value.

void application_init ( void )
{
    log_cfg_t log_cfg;
    brushless3_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.
    brushless3_cfg_setup( &cfg );
    BRUSHLESS3_MAP_MIKROBUS( cfg, MIKROBUS_1 );
    brushless3_init( &brushless3, &cfg );
    
    if ( BRUSHLESS3_ERROR == brushless3_default_cfg ( &brushless3 ) )
    {
        log_error( &logger, " Default configuration." );
        for ( ; ; );
    }
}

Application Task

This is an example which demonstrates the use of Brushless 3 Click board. Read and display float motor frequency value from the DRV10983 sensorless BLDC motor driver on Brushless 3 Click board. Results are being sent to the Usart Terminal where you can track their changes.

void application_task ( void )
{
    log_printf( &logger, "    acceleration      \r\n" );
    
    for ( speed = 100; speed <= BRUSHLESS3_MAX_SPEED; speed += 20 )
    {
        brushless3_set_speed( &brushless3, speed );
        brushless3_get_speed( &brushless3, &velocity );
        log_printf( &logger, " Motor frequency: %.2f Hz\r\n", velocity );
        Delay_ms ( 100 );
    }

    log_printf( &logger,  "\r\n ---------------------- \r\n" ); 
    log_printf( &logger, "    slowing down     \r\n" );
    
    for ( speed = BRUSHLESS3_MAX_SPEED; speed >= 50; speed -= 20 )
    {
        brushless3_set_speed( &brushless3, speed );
        brushless3_get_speed( &brushless3, &velocity );
        log_printf( &logger, " Motor frequency: %.2f Hz\r\n", velocity );
        Delay_ms ( 100 );
    }
    
    log_printf( &logger, "-----------------------\r\n" );
    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.
