Library Description

The library covers all the necessary functions that enables the usage of the Thermno 14 Click board. It holds functions that allow full control of the device to the user. User can calibrate the device, read temperature or read raw values if necessary.

Key functions:

• float thermo14_get_temperature ( ); - Function is used to get the temperature.
• float thermo14_raw_to_celsius ( int16_t temp_raw ); - Function is used to perform necessary calculacion in order to get temperature freom raw data.
• int16_t thermo14_temp_raw_get ( ); - Function is used to get the raw value.

Examples description

The application is composed of three sections :

• System Initialization - Initializes GPIO, SPI and LOG structures.
• Application Initialization - Initalizes SPI driver, sets up the device and makes an initial log.
• Application Task - (code snippet) This example shows capabilities of Thermo 14 click by measuring temperature every 3 seconds and displaying temperature in degrres Celsius via USART terminal.

void application_task ( )
{
    temp_val = thermo14_get_temperature( );

    mikrobus_logWrite( " Temperature: ", _LOG_TEXT );
    log_display( temp_val );
    mikrobus_logWrite( deg_cel, _LOG_LINE );

    mikrobus_logWrite( "----------------------", _LOG_LINE );
    Delay_ms( 3000 );
}

Additional Functions :

• void log_display( float value ) - Function displays readings as floating point value with two decimal places

Other mikroE Libraries used in the example:

• I2C
• UART
• Conversions

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.
