IR Thermo 4 Click

IR Thermo 4 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 IR Thermo 4 Click board by reading and displaying the ambient and object temperature measurements.

Example Libraries

• MikroSDK.Board
• MikroSDK.Log
• Click.IRThermo4

Example Key Functions

• irthermo4_cfg_setup Config Object Initialization function.

void irthermo4_cfg_setup ( irthermo4_cfg_t *cfg );

• irthermo4_init Initialization function.

err_t irthermo4_init ( irthermo4_t *ctx, irthermo4_cfg_t *cfg );

• irthermo4_default_cfg Click Default Configuration function.

err_t irthermo4_default_cfg ( irthermo4_t *ctx );

• irthermo4_read_ambient_temp This function reads and calculates the ambient temperature in degrees Celsius.

err_t irthermo4_read_ambient_temp ( irthermo4_t *ctx, float *t_amb );

• irthermo4_read_object_temp This function reads and calculates the object temperature in degrees Celsius.

err_t irthermo4_read_object_temp ( irthermo4_t *ctx, float *t_obj, float t_amb );

• irthermo4_get_int_pin This function returns the INT pin logic state.

uint8_t irthermo4_get_int_pin ( irthermo4_t *ctx );

Application Init

Initializes the driver and performs the Click default configuration.

void application_init ( void )
{
    log_cfg_t log_cfg;  /**< Logger config object. */
    irthermo4_cfg_t irthermo4_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.
    irthermo4_cfg_setup( &irthermo4_cfg );
    IRTHERMO4_MAP_MIKROBUS( irthermo4_cfg, MIKROBUS_POSITION_IRTHERMO4 );
    if ( I2C_MASTER_ERROR == irthermo4_init( &irthermo4, &irthermo4_cfg ) ) 
    {
        log_error( &logger, " Communication init." );
        for ( ; ; );
    }
    
    if ( IRTHERMO4_ERROR == irthermo4_default_cfg ( &irthermo4 ) )
    {
        log_error( &logger, " Default configuration." );
        for ( ; ; );
    }

    log_info( &logger, " Application Task " );
}

Application Task

Reads the ambient and object temperature measurements twice per second and displays the results on the USB UART.

void application_task ( void )
{
    float ambient_temp = 0;
    float object_temp = 0;
    if ( IRTHERMO4_OK == irthermo4_read_ambient_temp ( &irthermo4, &ambient_temp ) )
    {
        log_printf ( &logger, " Ambient temperature: %.2f degC\r\n", ambient_temp );
        if ( IRTHERMO4_OK == irthermo4_read_object_temp ( &irthermo4, &object_temp, ambient_temp ) )
        {
            log_printf ( &logger, " Object temperature: %.2f degC\r\n\n", object_temp );
        }
    }
    Delay_ms ( 500 );
}

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.
