Brushless 16 Click

Brushless 16 Click is a compact add-on board suitable for controlling BLDC motors with any MCU. This board features the LB11685AV, a three-phase full-wave current-linear-drive motor driver from ON Semiconductor.

Software Support

We provide a library for the Brushless16 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 Brushless16 Click driver.

Standard key functions :

• brushless16_cfg_setup Config Object Initialization function.

  void brushless16_cfg_setup ( brushless16_cfg_t *cfg );

• brushless16_init Initialization function.

  BRUSHLESS16_RETVAL brushless16_init ( brushless16_t *ctx, brushless16_cfg_t *cfg );

Example key functions :

• brushless16_set_en Set en pin state

  void brushless16_set_en ( brushless16_t *ctx, uint8_t state );

• brushless16_get_rd Get rd pin state.

  uint8_t brushless16_get_rd ( brushless16_t *ctx );

• brushless16_get_fg Get fg pin state.

  uint8_t brushless16_get_fg ( brushless16_t *ctx );

Example Description

This example showcases ability to enable and disable motor output, and check the status pins.

The demo application is composed of two sections :

Application Init

Initializon of UART module for log and pins for motor control.

void application_init ( void ) 
{
    log_cfg_t log_cfg;  /**< Logger config object. */
    brushless16_cfg_t brushless16_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.
    brushless16_cfg_setup( &brushless16_cfg );
    BRUSHLESS16_MAP_MIKROBUS( brushless16_cfg, MIKROBUS_1 );
    if ( brushless16_init( &brushless16, &brushless16_cfg ) == DIGITAL_OUT_UNSUPPORTED_PIN ) 
    {
        log_error( &logger, " Application Init Error. " );
        log_info( &logger, " Please, run program again... " );

        for ( ; ; );
    }
    Delay_ms ( 500 );
    log_info( &logger, " Application Task " );
}

Application Task

Checks state of information pins every ms, and stop and start motor output every second.

void application_task ( void ) 
{
    static uint16_t timer = 5000;
    static uint8_t state = 1;

    if ( brushless16_get_rd( &brushless16 ) )
    {
        log_info( &logger, " Motor Lock" );
        Delay_ms ( 500 );
    }

    if ( brushless16_get_fg( &brushless16 ) )
    {
        log_info( &logger, " FG" );
        Delay_ms ( 500 );
    }

    if ( !( timer-- ) )
    {
        timer = 5000;

        if ( state )
        {
            log_info( &logger, " Motor stop" );
        }
        else
        {
            log_info( &logger, " Motor rotating" );
        }

        brushless16_set_en( &brushless16, state );
        state = !state;
    }

    Delay_ms ( 1 );
}

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.Brushless16

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.
