Stepper 28 Click

Stepper 28 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 Stepper 28 Click board by driving the motor in both directions for a desired number of steps.

Example Libraries

• MikroSDK.Board
• MikroSDK.Log
• Click.Stepper28

Example Key Functions

• stepper28_cfg_setup This function initializes Click configuration structure to initial values.

  void stepper28_cfg_setup ( stepper28_cfg_t *cfg );

• stepper28_init This function initializes all necessary pins and peripherals used for this Click board.

  err_t stepper28_init ( stepper28_t *ctx, stepper28_cfg_t *cfg );

• stepper28_default_cfg This function executes a default configuration of Stepper 28 Click board.

  err_t stepper28_default_cfg ( stepper28_t *ctx );

• stepper28_set_direction This function sets the motor direction by setting the DIR pin logic state.

  void stepper28_set_direction ( stepper28_t *ctx, uint8_t dir );

• stepper28_set_step_mode This function sets the step mode resolution settings.

  err_t stepper28_set_step_mode ( stepper28_t *ctx, uint8_t mode );

• stepper28_drive_motor This function drives the motor for the specific number of steps at the selected speed.

  void stepper28_drive_motor ( stepper28_t *ctx, uint32_t steps, uint8_t speed );

Application Init

Initializes the driver and performs the Click default configuration.

void application_init ( void )
{
    log_cfg_t log_cfg;  
    stepper28_cfg_t stepper28_cfg;  

    LOG_MAP_USB_UART( log_cfg );
    log_init( &logger, &log_cfg );
    log_info( &logger, " Application Init " );
 
    // Click initialization.
    stepper28_cfg_setup( &stepper28_cfg );
    STEPPER28_MAP_MIKROBUS( stepper28_cfg, MIKROBUS_1 );
    if ( I2C_MASTER_ERROR == stepper28_init( &stepper28, &stepper28_cfg ) ) 
    {
        log_error( &logger, " Communication init." );
        for ( ; ; );
    }
    
    if ( STEPPER28_ERROR == stepper28_default_cfg ( &stepper28 ) )
    {
        log_error( &logger, " Default configuration." );
        for ( ; ; );
    }
    
    log_info( &logger, " Application Task " );
}

Application Task

Drives the motor clockwise for 200 full steps and then counter-clockwise for 200 half steps and 400 quarter steps with a 1 second delay on driving mode change. All data is being logged on the USB UART where you can track the program flow.

void application_task ( void )
{
    log_printf ( &logger, " Move 200 full steps clockwise, speed: slow\r\n\n" );
    stepper28_set_direction ( &stepper28, STEPPER28_DIR_CW );
    stepper28_set_step_mode ( &stepper28, STEPPER28_MODE_FULL_STEP );
    stepper28_drive_motor ( &stepper28, 200, STEPPER28_SPEED_SLOW );
    Delay_ms ( 1000 );
 
    log_printf ( &logger, " Move 200 half steps counter-clockwise, speed: medium\r\n\n" );
    stepper28_set_direction ( &stepper28, STEPPER28_DIR_CCW );
    stepper28_set_step_mode ( &stepper28, STEPPER28_MODE_HALF_STEP_TYPE_A );
    stepper28_drive_motor ( &stepper28, 200, STEPPER28_SPEED_MEDIUM );
    Delay_ms ( 1000 );
 
    log_printf ( &logger, " Move 400 quarter steps counter-clockwise, speed: fast\r\n\n" );
    stepper28_set_direction ( &stepper28, STEPPER28_DIR_CCW );
    stepper28_set_step_mode ( &stepper28, STEPPER28_MODE_QUARTER_STEP );
    stepper28_drive_motor ( &stepper28, 400, STEPPER28_SPEED_FAST );
    Delay_ms ( 1000 );
}

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.
