IrThermo 3 Click

IrThermo 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

The demo application displays ambient and object temperature measurements using IrThermo 3 Click.

Example Libraries

• MikroSDK.Board
• MikroSDK.Log
• Click.IrThermo3

Example Key Functions

• irthermo3_cfg_setup Config Object Initialization function.

void irthermo3_cfg_setup ( irthermo3_cfg_t *cfg ); 

• irthermo3_init Initialization function.

err_t irthermo3_init ( irthermo3_t *ctx, irthermo3_cfg_t *cfg );

• irthermo3_cal Calibration function

void irthermo3_cal ( irthermo3_t *ctx );

• irthermo3_get_ambient_temp Read Ambient Temperature function

float irthermo3_get_ambient_temp ( irthermo3_t *ctx );

• irthermo3_get_object_temp Read Object Temperature function

float irthermo3_get_object_temp ( irthermo3_t *ctx );

Application Init

Initializes the driver, resets the device and performs calibration.

void application_init ( void )
{
    log_cfg_t log_cfg;
    irthermo3_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_info( &logger, "---- Application Init ----" );

    //  Click initialization.
    irthermo3_cfg_setup( &cfg );
    IRTHERMO3_MAP_MIKROBUS( cfg, MIKROBUS_1 );
    irthermo3_init( &irthermo3, &cfg );

    irthermo3_cal ( &irthermo3 );
    Delay_ms ( 500 );
}

Application Task

The device measures ambient and object temperature in degrees Celsius and displays them on the USB UART once per second.

void application_task ( void )
{
    amb_temp = irthermo3_get_ambient_temp( &irthermo3 );
    log_printf( &logger, "Ambient temperature: %.2f degC \r\n", amb_temp );

    obj_temp = irthermo3_get_object_temp( &irthermo3 );
    log_printf( &logger, "Object temperature: %.2f degC \r\n", obj_temp );

    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.
