DC Motor 11 Click

DC Motor 11 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 application is motor driver with the current limiting and current sensing.

Example Libraries

• MikroSDK.Log
• Click.DcMotor11

Example Key Functions

• dcmotor11_cfg_setup Config Object Initialization function.

void dcmotor11_cfg_setup ( dcmotor11_cfg_t *cfg );

• dcmotor11_init Initialization function.

err_t dcmotor11_init ( dcmotor11_t *ctx, dcmotor11_cfg_t *cfg );

uint8_t dcmotor11_get_fault( dcmotor11_t *ctx );

• dcmotor11_get_interrupt_state Interrupt state on the INT pin.

uint8_t dcmotor11_get_interrupt_state( dcmotor11_t *ctx );

Application Init

Initialization driver init and sets first motor settings.

void application_init ( void )
{
    log_cfg_t log_cfg;
    dcmotor11_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.

}

Application Task

Waits for valid user input and executes functions based on set of valid commands.

    }
    else

        motor_dir = 2;
        dcmotor11_control( &dcmotor11, motor_dir, motor_speed );

}

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.
