EasyPull Click

EasyPull 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 EasyPull Click boards.

Example Libraries

• MikroSDK.Board
• MikroSDK.Log
• Click.EasyPull

Example Key Functions

• easypull_cfg_setup Config Object Initialization function.

void easypull_cfg_setup ( easypull_cfg_t *cfg );

• easypull_init Initialization function.

err_t easypull_init ( easypull_t *ctx, easypull_cfg_t *cfg );

• easypull_get_an_pin This function reads the state of the AN pin of EasyPull Click board.

uint8_t easypull_get_an_pin ( easypull_t *ctx );

• easypull_get_rst_pin This function reads the state of the RST pin of EasyPull Click board.

uint8_t easypull_get_rst_pin ( easypull_t *ctx );

• easypull_get_cs_pin This function reads the state of the CS pin of EasyPull Click board.

uint8_t easypull_get_cs_pin ( easypull_t *ctx );

Application Init

Initializes the driver and USB UART logger.

void application_init ( void ) 
{
    log_cfg_t log_cfg;  /**< Logger config object. */
    easypull_cfg_t easypull_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.
    easypull_cfg_setup( &easypull_cfg );
    EASYPULL_MAP_MIKROBUS( easypull_cfg, MIKROBUS_1 );
    if ( DIGITAL_OUT_UNSUPPORTED_PIN == easypull_init( &easypull, &easypull_cfg ) ) 
    {
        log_error( &logger, " Communication init." );
        for ( ; ; );
    }
    
    log_info( &logger, " Application Task " );
}

Application Task

It checks the state of the pins and displays their state on the USB UART.

void application_task ( void ) 
{
    if ( EASYPULL_PIN_STATE_HIGH == easypull_get_an_pin( &easypull ) )
    {
        log_printf( &logger, " AN pin state: HIGH \n" );
    }
    else
    {
        log_printf( &logger, " AN pin state: LOW \n" );
    }

    if ( EASYPULL_PIN_STATE_HIGH == easypull_get_rst_pin( &easypull ) )
    {
        log_printf( &logger, " RST pin state: HIGH \n" );
    }
    else
    {
        log_printf( &logger, " RST pin state: LOW \n" );
    }

    if ( EASYPULL_PIN_STATE_HIGH == easypull_get_cs_pin( &easypull ) )
    {
        log_printf( &logger, " CS pin state: HIGH \n" );
    }
    else
    {
        log_printf( &logger, " CS pin state: LOW \n" );
    }

    if ( EASYPULL_PIN_STATE_HIGH == easypull_get_pwm_pin( &easypull ) )
    {
        log_printf( &logger, " PWM pin state: HIGH \n" );
    }
    else
    {
        log_printf( &logger, " PWM pin state: LOW \n" );
    }

    if ( EASYPULL_PIN_STATE_HIGH == easypull_get_int_pin( &easypull ) )
    {
        log_printf( &logger, " INT pin state: HIGH \n" );
    }
    else
    {
        log_printf( &logger, " INT pin state: LOW \n" );
    }
    log_printf( &logger, "- - - - - - - - - - - - - \r\n" );
    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.
