Brushless 13 click

‍Brushless 13 Click is a compact add-on board that controls brushless DC motors with any MCU. This board features the STSPIN830, a compact and versatile three-phase and three-sense motor driver from STMicroelectronics. The driver integrates both the control logic and a fully protected low RDson triple half-bridge power stage.

Click library

• Author : Stefan Ilic
• Date : Aug 2023.
• Type : I2C type

Software Support

We provide a library for the Brushless 13 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 13 Click driver.

Standard key functions :

• brushless13_cfg_setup Config Object Initialization function.

  void brushless13_cfg_setup ( brushless13_cfg_t *cfg );

• brushless13_init Initialization function.

  err_t brushless13_init ( brushless13_t *ctx, brushless13_cfg_t *cfg );

• brushless13_default_cfg Click Default Configuration function.

  err_t brushless13_default_cfg ( brushless13_t *ctx );

Example key functions :

• brushless13_set_mode Brushless 13 set mode pin function.

  void brushless13_set_mode ( brushless13_t *ctx, uint8_t mode_sel );

• brushless13_get_flt_pin Brushless 13 get fault pin function.

  uint8_t brushless13_get_flt_pin ( brushless13_t *ctx );

• brushless13_drive_motor Brushless 13 drive motor function.

  err_t brushless13_drive_motor ( brushless13_t *ctx, uint8_t dir, uint8_t speed, uint32_t time_ms );

Example Description

‍This example demonstrates the use of the Brushless 13 click board by driving the motor in both directions at different speeds.

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;  
    brushless13_cfg_t brushless13_cfg;  
    LOG_MAP_USB_UART( log_cfg );
    log_init( &logger, &log_cfg );
    log_info( &logger, " Application Init " );
 
    // Click initialization.
    brushless13_cfg_setup( &brushless13_cfg );
    BRUSHLESS13_MAP_MIKROBUS( brushless13_cfg, MIKROBUS_1 );
    if ( I2C_MASTER_ERROR == brushless13_init( &brushless13, &brushless13_cfg ) ) 
    {
        log_error( &logger, " Communication init." );
        for ( ; ; );
    }
    
    if ( BRUSHLESS13_ERROR == brushless13_default_cfg ( &brushless13 ) )
    {
        log_error( &logger, " Default configuration." );
        for ( ; ; );
    }
    
    log_info( &logger, " Application Task " );
}

Application Task

‍Drives the motor in both directions and changes the motor speed approximately every 2 seconds. The driving direction and speed will be displayed on the USB UART.

void application_task ( void ) 
{
    log_printf ( &logger, "\r\n Driving motor clockwise \r\n" );
    for ( uint8_t speed = BRUSHLESS13_SPEED_MIN; speed <= BRUSHLESS13_SPEED_MAX; speed += 20 )
    {
        log_printf ( &logger, " Speed gain: %u\r\n", ( uint16_t ) speed );
        if ( BRUSHLESS13_OK != brushless13_drive_motor ( &brushless13, BRUSHLESS13_DIR_CW, speed, 2000 ) )
        {
            log_error ( &logger, " Drive motor " );
        }
    }
    Delay_ms ( 1000 );
    
    log_printf ( &logger, "\r\n Driving motor counter-clockwise \r\n" );
    for ( uint8_t speed = BRUSHLESS13_SPEED_MIN; speed <= BRUSHLESS13_SPEED_MAX; speed += 20 )
    {
        log_printf ( &logger, " Speed gain: %u\r\n", ( uint16_t ) speed );
        if ( BRUSHLESS13_OK != brushless13_drive_motor ( &brushless13, BRUSHLESS13_DIR_CCW, speed, 2000 ) )
        {
            log_error ( &logger, " Drive motor " );
        }
    }
    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.Brushless13

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.
