DC Motor 21 Click

DC Motor 21 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 DC Motor 21 Click board.

Example Libraries

• MikroSDK.Board
• MikroSDK.Log
• Click.DCMotor21

Example Key Functions

• dcmotor21_cfg_setup Config Object Initialization function.

void dcmotor21_cfg_setup ( dcmotor21_cfg_t *cfg );

• dcmotor21_init Initialization function.

err_t dcmotor21_init ( dcmotor21_t *ctx, dcmotor21_cfg_t *cfg );

• dcmotor21_default_cfg Click Default Configuration function.

void dcmotor21_default_cfg ( dcmotor21_t *ctx );

• dcmotor21_set_out_1 This function sets the state of output 1.

void dcmotor21_set_out_1 ( dcmotor21_t *ctx, uint8_t state );

• dcmotor21_set_out_2 This function sets the state of output 2.

void dcmotor21_set_out_2 ( dcmotor21_t *ctx, uint8_t state );

Application Init

Initializes the driver and performs the Click default configuration.

void application_init ( void )
{
    log_cfg_t log_cfg;  /**< Logger config object. */
    dcmotor21_cfg_t dcmotor21_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.
    dcmotor21_cfg_setup( &dcmotor21_cfg );
    DCMOTOR21_MAP_MIKROBUS( dcmotor21_cfg, MIKROBUS_1 );
    if ( DIGITAL_OUT_UNSUPPORTED_PIN == dcmotor21_init( &dcmotor21, &dcmotor21_cfg ) ) 
    {
        log_error( &logger, " Communication init." );
        for ( ; ; );
    }
    
    dcmotor21_default_cfg ( &dcmotor21 );
    
    log_info( &logger, " Application Task " );
}

Application Task

In the span of six seconds, it drives the motor in one direction, then switches the direction, and after that disconnects the motor. Each step will be logged on the USB UART where you can track the program flow.

void application_task ( void )
{
    dcmotor21_set_out_1 ( &dcmotor21, DCMOTOR21_OUT_LOW );
    dcmotor21_set_out_2 ( &dcmotor21, DCMOTOR21_OUT_HIGH );
    log_printf( &logger, " \r\n Driving the motor...\r\n" );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    dcmotor21_set_out_1 ( &dcmotor21, DCMOTOR21_OUT_HIGH );
    dcmotor21_set_out_2 ( &dcmotor21, DCMOTOR21_OUT_LOW );
    log_printf( &logger, " Switch direction.\r\n" );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    dcmotor21_set_out_1 ( &dcmotor21, DCMOTOR21_OUT_HIGH_Z );
    dcmotor21_set_out_2 ( &dcmotor21, DCMOTOR21_OUT_HIGH_Z );
    log_printf( &logger, " The motor is disconnected.\r\n" );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
}

Note

For this example, a DC motor should be connected to OUT1 and OUT2 lines.

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.
