DC Motor 32 Click

DC Motor 32 Click demo application is developed using the NECTO Studio, ensuring compatibility with mikroSDK's open-source libraries and tools. Designed for plug-and-play implementation and testing, the demo is fully compatible with all development, starter, and mikromedia boards featuring a mikroBUS™ socket.

Example Description

This example demonstrates the use of the DC Motor 32 Click board for controlling a DC motor. The application switches between different operation modes (forward, brake, reverse, and off) and measures the output current in each state.

Example Libraries

• MikroSDK.Board
• MikroSDK.Log
• Click.DCMotor32

Example Key Functions

• dcmotor32_cfg_setup This function initializes Click configuration structure to initial values.

  void dcmotor32_cfg_setup ( dcmotor32_cfg_t *cfg );

• dcmotor32_init This function initializes all necessary pins and peripherals used for this Click board.

  err_t dcmotor32_init ( dcmotor32_t *ctx, dcmotor32_cfg_t *cfg );

• dcmotor32_default_cfg This function executes a default configuration of DC Motor 32 Click board.

  err_t dcmotor32_default_cfg ( dcmotor32_t *ctx );

• dcmotor32_set_operation_mode This function sets the selected device operation mode.

  err_t dcmotor32_set_operation_mode ( dcmotor32_t *ctx, uint8_t mode );

• dcmotor32_get_out_current This function calculates the output current from the measured ADC voltage.

  err_t dcmotor32_get_out_current ( dcmotor32_t *ctx, float *current );

Application Init

Initializes the logger and DC Motor 32 Click driver, and applies the default configuration.

void application_init ( void )
{
    log_cfg_t log_cfg;  
    dcmotor32_cfg_t dcmotor32_cfg;  

    LOG_MAP_USB_UART( log_cfg );
    log_init( &logger, &log_cfg );
    log_info( &logger, " Application Init " );
 
    // Click initialization.
    dcmotor32_cfg_setup( &dcmotor32_cfg );
    DCMOTOR32_MAP_MIKROBUS( dcmotor32_cfg, MIKROBUS_POSITION_DCMOTOR32 );
    if ( DCMOTOR32_OK != dcmotor32_init( &dcmotor32, &dcmotor32_cfg ) )
    {
        log_error( &logger, " Communication init." );
        for ( ; ; );
    }
    
    if ( DCMOTOR32_OK != dcmotor32_default_cfg ( &dcmotor32 ) )
    {
        log_error( &logger, " Default configuration." );
        for ( ; ; );
    }
    
    log_info( &logger, " Application Task " );
}

Application Task

Cycles through motor operation modes, measures the output current, and logs the results to the serial terminal.

void application_task ( void )
{
    float current = 0;
    if ( DCMOTOR32_OK == dcmotor32_set_operation_mode ( &dcmotor32, DCMOTOR32_CONTROL_MODE_FORWARD_HSB ) )
    {
        log_printf( &logger, " MODE: Forward\r\n\n" );
        Delay_ms ( 1000 );
        Delay_ms ( 1000 );
        if ( DCMOTOR32_OK == dcmotor32_get_out_current ( &dcmotor32, &current ) ) 
        {
            log_printf( &logger, " Current : %.3f A\r\n\n", current );
        }
    }
    if ( DCMOTOR32_OK == dcmotor32_set_operation_mode ( &dcmotor32, DCMOTOR32_CONTROL_MODE_SLOW_DECAY_LSA ) )
    {
        log_printf( &logger, " MODE: Brake\r\n\n" );
        Delay_ms ( 1000 );
        Delay_ms ( 1000 );
        if ( DCMOTOR32_OK == dcmotor32_get_out_current ( &dcmotor32, &current ) ) 
        {
            log_printf( &logger, " Current : %.3f A\r\n\n", current );
        }
    }
    if ( DCMOTOR32_OK == dcmotor32_set_operation_mode ( &dcmotor32, DCMOTOR32_CONTROL_MODE_REVERSE_HSA ) )
    {
        log_printf( &logger, " MODE: Reverse\r\n\n" );
        Delay_ms ( 1000 );
        Delay_ms ( 1000 );
        if ( DCMOTOR32_OK == dcmotor32_get_out_current ( &dcmotor32, &current ) ) 
        {
            log_printf( &logger, " Current : %.3f A\r\n\n", current );
        }
    }
    if ( DCMOTOR32_OK == dcmotor32_set_operation_mode ( &dcmotor32, DCMOTOR32_CONTROL_MODE_HALF_BRIDGE_A_TRI_STATE ) )
    {
        log_printf( &logger, " MODE: Off\r\n\n" );
        Delay_ms ( 1000 );
        Delay_ms ( 1000 );
        if ( DCMOTOR32_OK == dcmotor32_get_out_current ( &dcmotor32, &current ) ) 
        {
            log_printf( &logger, " Current : %.3f A\r\n\n", current );
        }
    }
}

Application Output

This Click board can be interfaced and monitored in two ways:

• Application Output - Use the "Application Output" window in Debug mode for real-time data monitoring. Set it up properly by following this tutorial.
• UART Terminal - Monitor data via the UART Terminal using a USB to UART converter. For detailed instructions, check out this tutorial.

Additional Notes and Information

The complete application code and a ready-to-use project are available through the NECTO Studio Package Manager for direct installation in the NECTO Studio. The application code can also be found on the MIKROE GitHub account.
