Tester 3 Click

Tester 3 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 Tester 3 Click board by controlling all LEDs on the Click board together and in sequential pin toggling with different delays.

Example Libraries

• MikroSDK.Board
• MikroSDK.Log
• Click.Tester3

Example Key Functions

• tester3_cfg_setup This function initializes Click configuration structure to initial values.

  void tester3_cfg_setup ( tester3_cfg_t *cfg );

• tester3_init This function initializes all necessary pins and peripherals used for this Click board.

  err_t tester3_init ( tester3_t *ctx, tester3_cfg_t *cfg );

• tester3_toggle_all This function toggles all mikroBUS pins together a desired number of times with the selected delay between each toggle.

  void tester3_toggle_all ( tester3_t *ctx, uint16_t num_toggles, uint16_t toggle_delay_ms );

• tester3_toggle_seq This function toggles all mikroBUS pins one by one with the selected delay between each toggle.

  void tester3_toggle_seq ( tester3_t *ctx, uint16_t toggle_delay_ms );

Application Init

Initializes the driver and logger.

void application_init ( void )
{
    log_cfg_t log_cfg;  
    tester3_cfg_t tester3_cfg;  

    LOG_MAP_USB_UART( log_cfg );
    log_init( &logger, &log_cfg );
    log_info( &logger, " Application Init " );
 
    // Click initialization.
    tester3_cfg_setup( &tester3_cfg );
    TESTER3_MAP_MIKROBUS( tester3_cfg, MIKROBUS_POSITION_TESTER3 );
    if ( DIGITAL_OUT_UNSUPPORTED_PIN == tester3_init( &tester3, &tester3_cfg ) ) 
    {
        log_error( &logger, " Communication init." );
        for ( ; ; );
    }
    
    log_info( &logger, " Application Task " );
}

Application Task

Toggles all pins together 5 times with a 500ms delay between each toggle, then toggles each pin sequentially with a 300ms delay between toggling each pin.

void application_task ( void )
{
    log_printf( &logger, " Toggling all pins together 5 times with 500ms delay\r\n\n" );
    tester3_toggle_all ( &tester3, 5, 500 );
 
    log_printf( &logger, " Toggling all pins sequentially with 300ms delay\r\n\n" );
    tester3_toggle_seq ( &tester3, 300 );
}

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.
