Click library

  • Author : MikroE Team
  • Date : Jan 2020.
  • Type : I2C type

Software Support

We provide a library for the Brushless3 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 Brushless3 Click driver.

Standard key functions :

  • brushless3_cfg_setup Config Object Initialization function.

    void brushless3_cfg_setup ( brushless3_cfg_t *cfg );
  • brushless3_init Initialization function.

    err_t brushless3_init ( brushless3_t *ctx, brushless3_cfg_t *cfg );
  • brushless3_default_cfg Click Default Configuration function.

    err_t brushless3_default_cfg ( brushless3_t *ctx );

Example key functions :

  • brushless3_set_speed Set speed function

    err_t brushless3_set_speed ( brushless3_t *ctx, uint16_t motor_speed_hz );
  • brushless3_get_speed Get speed function

    err_t brushless3_get_speed ( brushless3_t *ctx, float *speed );
  • brushless3_forward_direction Set the direction of rotation in the forward direction function

    void brushless3_forward_direction ( brushless3_t *ctx );

Examples Description

This Click has three-phase sensorless motor driver and with an external power supply it drives a brushless DC motor.

The demo application is composed of two sections :

Application Init

Initialization driver enable's - I2C, set default parameter value.


void application_init ( void )
{
    log_cfg_t log_cfg;
    brushless3_cfg_t cfg;

    /** 
     * 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.
    brushless3_cfg_setup( &cfg );
    BRUSHLESS3_MAP_MIKROBUS( cfg, MIKROBUS_1 );
    brushless3_init( &brushless3, &cfg );

    if ( BRUSHLESS3_ERROR == brushless3_default_cfg ( &brushless3 ) )
    {
        log_error( &logger, " Default configuration." );
        for ( ; ; );
    }
}

Application Task

This is an example which demonstrates the use of Brushless 3 Click board. Read and display float motor frequency value from the DRV10983 sensorless BLDC motor driver on Brushless 3 Click board. Results are being sent to the Usart Terminal where you can track their changes.


void application_task ( void )
{
    log_printf( &logger, "    acceleration      \r\n" );

    for ( speed = 100; speed <= BRUSHLESS3_MAX_SPEED; speed += 20 )
    {
        brushless3_set_speed( &brushless3, speed );
        brushless3_get_speed( &brushless3, &velocity );
        log_printf( &logger, " Motor frequency: %.2f Hz\r\n", velocity );
        Delay_ms ( 100 );
    }

    log_printf( &logger,  "\r\n ---------------------- \r\n" ); 
    log_printf( &logger, "    slowing down     \r\n" );

    for ( speed = BRUSHLESS3_MAX_SPEED; speed >= 50; speed -= 20 )
    {
        brushless3_set_speed( &brushless3, speed );
        brushless3_get_speed( &brushless3, &velocity );
        log_printf( &logger, " Motor frequency: %.2f Hz\r\n", velocity );
        Delay_ms ( 100 );
    }

    log_printf( &logger, "-----------------------\r\n" );
    Delay_ms ( 1000 );
}  

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.Brushless3

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.
