Brushless 6 Click

Brushless 6 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 : PWM type

Software Support

Example Description

Brushless 6 Click is designed to drive a three-phase sensorless.

Example Libraries

• MikroSDK.Board
• MikroSDK.Log
• Click.Brushless6

Example Key Functions

• brushless6_cfg_setup Config Object Initialization function.

void brushless6_cfg_setup ( brushless6_cfg_t *cfg ); 

• brushless6_init Initialization function.

err_t brushless6_init ( brushless6_t *ctx, brushless6_cfg_t *cfg );

• brushless6_pwm_start Start PWM module.

void brushless6_pwm_start ( brushless6_t *ctx );

• brushless6_pwm_stop Stop PWM module.

void brushless6_pwm_stop ( brushless6_t *ctx );

• brushless6_set_duty_cycle Generic sets PWM duty cycle.

void brushless6_set_duty_cycle ( brushless6_t *ctx, float duty_cycle );

Application Init

This function initializes and configures the logger and the Click board.

void application_init ( void )
{
    log_cfg_t log_cfg;
    brushless6_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.

    brushless6_cfg_setup( &cfg );
    BRUSHLESS6_MAP_MIKROBUS( cfg, MIKROBUS_1 );
    brushless6_init( &brushless6, &cfg );
    brushless6_calibration( );
    brushless6_setings( );
}

Application Task

This function drives the motor in both directions increasing and decreasing the speed of the motor.

void application_task ( void )
{
    clockwise( );
    counter_clockwise( );
}

Note

The maximal PWM Clock frequency for this Click board is 500 Hz. So, the user will need to decrease the MCU's main clock frequency in MCU Settings in order to get up-to 500 Hz PWM clock frequency.

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.
