Click library

  • Author : Stefan Filipovic
  • Date : Aug 2024.
  • Type : SPI type

Software Support

We provide a library for the Brushless 30 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 from NECTO Studio Package Manager(recommended way), downloaded from our LibStock™ or found on Mikroe github account.

Library Description

This library contains API for Brushless 30 Click driver.

Standard key functions :

  • brushless30_cfg_setup Config Object Initialization function.

    void brushless30_cfg_setup ( brushless30_cfg_t *cfg );
  • brushless30_init Initialization function.

    err_t brushless30_init ( brushless30_t *ctx, brushless30_cfg_t *cfg );
  • brushless30_default_cfg Click Default Configuration function.

    err_t brushless30_default_cfg ( brushless30_t *ctx );

Example key functions :

  • brushless30_write_reg This function writes a data word to the selected register by using SPI serial interface.

    err_t brushless30_write_reg ( brushless30_t *ctx, uint8_t reg, uint16_t data_in );
  • brushless30_read_reg This function reads a data word from the selected register by using SPI serial interface.

    err_t brushless30_read_reg ( brushless30_t *ctx, uint8_t reg, uint16_t *data_out );
  • brushless30_get_diag_pin This function returns the DIAG pin logic state.

    uint8_t brushless30_get_diag_pin ( brushless30_t *ctx );

Example Description

This example configures the Brushless 30 Click board and makes it ready for the motor control over 6 PWM input signals.

The demo application is composed of two sections :

Application Init

Initializes the driver and performs the Click default configuration.


void application_init ( void )
{
    log_cfg_t log_cfg;  /**< Logger config object. */
    brushless30_cfg_t brushless30_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.
    brushless30_cfg_setup( &brushless30_cfg );
    BRUSHLESS30_MAP_MIKROBUS( brushless30_cfg, MIKROBUS_1 );
    if ( SPI_MASTER_ERROR == brushless30_init( &brushless30, &brushless30_cfg ) )
    {
        log_error( &logger, " Communication init." );
        for ( ; ; );
    }

    if ( BRUSHLESS30_ERROR == brushless30_default_cfg ( &brushless30 ) )
    {
        log_error( &logger, " Default configuration." );
        for ( ; ; );
    }

    log_printf( &logger, " Click is configured successfully.\r\n" );
    log_printf( &logger, " Apply a 6 PWM signals to UVW H/L pins to drive the motor.\r\n" );

    log_info( &logger, " Application Task " );
}

Application Task

Monitors the DIAG pin state, displays the STAT1 and STAT2 registers on the USB UART, and clears the set flags.

void application_task ( void )
{
    uint16_t status = 0;
    if ( !brushless30_get_diag_pin ( &brushless30 ) )
    {
        if ( BRUSHLESS30_OK == brushless30_read_reg ( &brushless30, BRUSHLESS30_REG_STAT1, &status ) )
        {
            if ( status )
            {
                log_printf( &logger, " STAT1: 0x%.4X\r\n", status );
                if ( BRUSHLESS30_OK == brushless30_write_reg ( &brushless30, BRUSHLESS30_REG_STAT1, status ) )
                {
                    log_printf( &logger, " STAT1: cleared\r\n" );
                }
            }
        }

        if ( BRUSHLESS30_OK == brushless30_read_reg ( &brushless30, BRUSHLESS30_REG_STAT2, &status ) )
        {
            if ( status )
            {
                log_printf( &logger, " STAT2: 0x%.4X\r\n", status );
                if ( BRUSHLESS30_OK == brushless30_write_reg ( &brushless30, BRUSHLESS30_REG_STAT2, status ) )
                {
                    log_printf( &logger, " STAT2: cleared\r\n" );
                }
            }
        }

        Delay_ms ( 1000 );
    }
}

The full application code, and ready to use projects can be installed directly from NECTO Studio Package Manager(recommended way), downloaded from our LibStock™ or found on Mikroe github account.

Other Mikroe Libraries used in the example:

  • MikroSDK.Board
  • MikroSDK.Log
  • Click.Brushless30

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. UART terminal is available in all MikroElektronika compilers.
