Ir Eclipse Click

Ir Eclipse 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 is an example of IR ECLIPSE Click board.

Example Libraries

• MikroSDK.Board
• MikroSDK.Log
• Click.IrEclipse

Example Key Functions

• ireclipse_cfg_setup Config Object Initialization function.

void ireclipse_cfg_setup ( ireclipse_cfg_t *cfg );

• ireclipse_init Initialization function.

err_t ireclipse_init ( ireclipse_t *ctx, ireclipse_cfg_t *cfg );

• ireclipse_default_cfg Click Default Configuration function.

void ireclipse_default_cfg ( ireclipse_t *ctx );

• ireclipse_int_status Detecting states of IR beam from EE-SX198 photo interrupter sensor.

uint8_t ireclipse_int_status ( ireclipse_t *ctx );

Application Init

Configuring Clicks and log objects.

void application_init ( void )
{
    log_cfg_t log_cfg;
    ireclipse_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_printf(&logger, "- Application Init -\r\n");

    //  Click initialization.

    ireclipse_cfg_setup( &cfg );
    IRECLIPSE_MAP_MIKROBUS( cfg, MIKROBUS_1 );
    ireclipse_init( &ireclipse, &cfg );
    log_printf( &logger, "--------------------\r\n" );
    log_printf( &logger, "   Start counting:  \r\n" );
    log_printf( &logger, "--------------------\r\n" );
    
    n_cnt = IRECLIPSE_START_CNT_VAL;
    state_old = IRECLIPSE_LOW;
    state_new = IRECLIPSE_LOW;
}

Application Task

This is a example which demonstrates the use of IR eclipse Click board. When the beam from the transmitter is eclipsed by placing an object in the gap ( like a piece of paper ), when the sensor is triggered, the counter is incremented by one. Results are being sent to the Usart Terminal where you can track their changes. Data logs on usb uart when the sensor is triggered.

void application_task ( void )
{
    state_new = ireclipse_int_status( &ireclipse );

    if ( ( state_new == IRECLIPSE_HIGH ) && ( state_old == IRECLIPSE_LOW ) )
    {
        state_old = IRECLIPSE_HIGH;
        log_printf( &logger, "  Counter = %d \r\n", n_cnt );
    
        n_cnt++;
    }

    if ( ( state_new == IRECLIPSE_LOW ) && ( state_old == IRECLIPSE_HIGH ) )
    {
        log_printf( &logger, "--------------------\r\n" );
        state_old = IRECLIPSE_LOW;
    }
}

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.
