Click library

• Author : MikroE Team
• Date : nov 2019.
• Type : I2C type

Software Support

We provide a library for the IrThermo3 Click as well as a demo application (example), developed using MikroElektronika compilers. The demo can run on all the main MikroElektronika development boards.

Package can be downloaded/installed directly form compilers IDE(recommended way), or downloaded from our LibStock, or found on mikroE github account.

Library Description

‍This library contains API for IrThermo3 Click driver.

Standard 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 );

Example key functions :

• 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 );

Examples Description

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

The demo application is composed of two sections :

Application Init

‍Initializes the driver, resets the device and performs calibration.

void application_init ( void )
{
    log_cfg_t log_cfg;
    irthermo3_cfg_t cfg;
 
    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 );
}

The full application code, and ready to use projects can be installed directly form compilers IDE(recommneded) or found on LibStock page or mikroE GitHub accaunt.

Other mikroE Libraries used in the example:

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

Additional notes and informations

Depending on the development board you are using, you may need USB UART click, USB UART 2 Click or RS232 Click to connect to your PC, for development systems with no UART to USB interface available on the board. The terminal available in all Mikroelektronika compilers, or any other terminal application of your choice, can be used to read the message.
