Click library

  • Author : Luka Filipovic
  • Date : Jul 2021.
  • Type : I2C type

Software Support

We provide a library for the Brushless14 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 Brushless14 Click driver.

Standard key functions :

  • brushless14_cfg_setup Config Object Initialization function.

    void brushless14_cfg_setup ( brushless14_cfg_t *cfg );
  • brushless14_init Initialization function.

    err_t brushless14_init ( brushless14_t *ctx, brushless14_cfg_t *cfg );
  • brushless14_default_cfg Click Default Configuration function.

    err_t brushless14_default_cfg ( brushless14_t *ctx );

Example key functions :

  • brushless14_set_duty_cycle Sets PWM duty cycle.

    err_t brushless14_set_duty_cycle ( brushless14_t *ctx, float duty_cycle );
  • brushless14_set_la Set lead angle setting input.

    err_t brushless14_set_la ( brushless14_t *ctx, uint16_t m_voltage );
  • brushless14_set_dir Set dirrection pin state.

    void brushless14_set_dir ( brushless14_t *ctx, uint8_t state );

Example Description

This application example showcases ability of the device to control motor, It's speed and rotation direction. Also it gives user ability to change other configuration parameters.

The demo application is composed of two sections :

Application Init

Initialization of communication modules (I2C, PWM, UART) and additional pins (INT, DIR). It reads ID from DAC ic to confirm communcation. Then configures device for control.


void application_init ( void ) 
{
    log_cfg_t log_cfg;  /**< Logger config object. */
    brushless14_cfg_t brushless14_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.
    brushless14_cfg_setup( &brushless14_cfg );
    BRUSHLESS14_MAP_MIKROBUS( brushless14_cfg, MIKROBUS_1 );
    err_t init_flag = brushless14_init( &brushless14, &brushless14_cfg );
    if ( I2C_MASTER_ERROR == init_flag ) 
    {
        log_error( &logger, " Application Init Error. " );
        log_info( &logger, " Please, run program again... " );

        for ( ; ; );
    }

    uint16_t data_read = 0;
    brushless14_dac_read( &brushless14, 0x02, &data_read);
    if ( BRUSHLESS14_DAC_ID != data_read )
    {
        log_error( &logger, " Communication. " );
    }

    brushless14_default_cfg ( &brushless14 );

    Delay_ms( 1000 );
    log_info( &logger, " Application Task " );
}

Application Task

Drives motor using PWM from 10% duty cycle to 100% and back to 0%. Increment is done by 10% in span of 2 seconds. Whenever application gets to 0% duty cycle it chages direction of rotation.


void application_task ( void ) 
{
    static int8_t duty_cnt = 1;
    static int8_t duty_inc = 1;
    static uint8_t direction = 0;
    float duty = duty_cnt / 10.0;

    brushless14_set_duty_cycle ( &brushless14, duty );
    log_printf( &logger, "> Duty: %d%%\r\n", ( uint16_t )( duty_cnt * 10 ) );

    Delay_ms( 2000 );

    if ( 10 == duty_cnt ) 
    {
        duty_inc = -1;
    }
    else if ( 0 == duty_cnt ) 
    {
        duty_inc = 1;
        direction = !direction;
        brushless14_set_dir( &brushless14, direction );
    }
    duty_cnt += duty_inc;
}

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.Brushless14

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.

UV 5 Click is a compact add-on board that can measure UV radiation. This board features the AS7331, a spectral UVA/B/C sensor from ams. The sensor can measure UVA, UVB, and UVC, which are the main types of UV rays from the UV radiation of the sunlight. It uses ADC with a high dynamic range (16… 24-bit) for measurements from low to high radiation conditions and has a high sensitivity, which makes it usable for fluorescence light conditions.

Proximity 18 Click is a compact add-on board that contains a close-range proximity sensing solution. This board features the VCNL3036X01, a high-resolution digital proximity sensor from Vishay Semiconductors. Besides the proximity sensor, the VCNL3036X01 also integrates a mux and a driver for three external LEDs, which are located near the chip on the board, photodiodes, amplifiers, and analog to digital converting circuits into a single chip by CMOS process. It allows absolute distance measurement, whatever the target color and reflectance, providing an accurate range of up to 50cm.
