IR SENSE Click

IR SENSE 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.

Application Init

Initialization driver enables - I2C, enable sensor, set soft reset, set Continuous Mode 0, also write log.

void application_init ( void )
{
    log_cfg_t log_cfg;
    irsense_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.

Application Task

This is an example which demonstrates the use of IR Sense Click board. Detects the temperature of objects and detects the motion in observable area of the AK9750 sensor. Results are being sent to the Usart Terminal where you can track their changes. All data logs write on usb uart changes for every 1 sec.

void application_task ( void )
{
   if ( irsense_check_available( &irsense ) )
    {
        irsense_get_ir_sense( &irsense, &bottom_area, &left_area, &right_area, &top_area );

        log_printf( &logger, "- - - - - - - - -\r\n" );
        log_printf( &logger, " Bottom : %d \r\n", bottom_area );

        log_printf( &logger, " Left   : %d \r\n", left_area );

        log_printf( &logger, " Top    : %d \r\n", top_area );

        log_printf( &logger, " Right  : %d \r\n", right_area );
        log_printf( &logger, "- - - - - - - - -\r\n" );

        temperature = irsense_get_temperature( &irsense );
        log_printf( &logger, " Temperature: %f \r\n", temperature );
        log_printf( &logger, "---------------------------\r\n" );

        irsense_refresh( &irsense );
        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.
