Software Support

We provide a library for the Brushless7 Click as well as a demo application (example), developed using MikroElektronika compilers. The demo can run on all the main MikroElektronika development boards.

Package can be downloaded/installed directly form compilers IDE(recommended way), or downloaded from our LibStock, or found on mikroE github account.

Library Description

This library contains API for Brushless7 Click driver.

Standard key functions :

• Config Object Initialization function.

  void brushless7_cfg_setup ( brushless7_cfg_t *cfg );

• Initialization function.

  BRUSHLESS7_RETVAL brushless7_init ( brushless7_t ctx, brushless7_cfg_t cfg );

• Click Default Configuration function.

  void brushless7_default_cfg ( brushless7_t *ctx );

Example key functions :

• Function for changeing duty of device

  uint8_t brushless7_change_duty ( brushless7_t *ctx, float duty_ptc );

• Function for setting max rpm parameter of device

  uint8_t brushless7_max_speed_rpm ( brushless7_t *ctx, uint8_t max_speed_rpm );

• Function for setting type of device control

  uint8_t brushless7_control_mode_set ( brushless7_t *ctx, uint8_t ctrl_type );

Examples Description

This example demonstrates the use of Brushless 7 Click board.

The demo application is composed of two sections :

Application Init

Sets the default configuration and then configures the Click board for the selected mode.

void application_init ( void )
{
    log_cfg_t log_cfg;
    brushless7_cfg_t cfg;
    uint8_t error_flag = 0;

    /** 
     * 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.

    brushless7_cfg_setup( &cfg );
    BRUSHLESS7_MAP_MIKROBUS( cfg, MIKROBUS_1 );
    brushless7_init( &brushless7, &cfg );
    Delay_ms ( 100 );

    brushless7_default_cfg( &brushless7 );
    Delay_ms ( 100 );

    demo_type_data = BRUSHLESS7_CTRL_TYPE_DUTY;

    if ( BRUSHLESS7_CTRL_TYPE_DUTY == demo_type_data )
    {
        error_flag |= brushless7_max_duty( &brushless7, 95.0 );
        error_flag |= brushless7_start_duty( &brushless7, 5.0 );
        error_flag |= brushless7_stop_duty( &brushless7, 2.0 );
        log_printf( &logger, " ----- DUTY CONTROL ----- \r\n" );
    }
    else if ( BRUSHLESS7_CTRL_TYPE_RPM == demo_type_data )
    {
        error_flag |= brushless7_max_speed_rpm( &brushless7, BRUSHLESS7_MAX_SPEED_4096 );
        log_printf( &logger, " ----- RPM CONTROL ----- \r\n" );
    }

    if ( BRUSHLESS7_DEV_ERROR == error_flag )
    {
        log_printf( &logger, " ----- ERROR ----- \r\n" );
        for( ; ; );
    }
}

Application Task

Increases and decreases the speed of the motor rotation by setting the duty cycle or rpm values depending on which mode is previously selected. It also switches the direction of rotation at the beginning of each cycle. All data is being logged on the USB UART where you can track their changes.

The full application code, and ready to use projects can be installed directly form compilers IDE(recommneded) or found on LibStock page or mikroE GitHub accaunt.

Other mikroE Libraries used in the example:

• MikroSDK.Board
• MikroSDK.Log
• Click.Brushless7

Additional notes and informations

Depending on the development board you are using, you may need USB UART Click, USB UART 2 Click or RS232 Click to connect to your PC, for development systems with no UART to USB interface available on the board. The terminal available in all Mikroelektronika compilers, or any other terminal application of your choice, can be used to read the message.
