Library Description

The library covers all the necessary functions to control Thermo 20 board™ board. Library performs a standard I2C interface communication.

Key functions:

• float thermo20_get_temperature ( void ) - Get temperature data function.
• void thermo20_soft_reset ( void ) - Soft reset function.
• void thermo20_start_conversion ( void ) - Start conversion function.

Examples description

The application is composed of three sections :

• System Initialization - Initializes I2C and start to write log.
• Application Initialization - Initialization driver enables - I2C, software reset the device and read the serial number, also write log.
• Application Task - (code snippet) This is an example that demonstrates the use of the Thermo 20 click board™. Thermo 20 click board™ can be used to measure temperature. All data logs write on USB UART changes every 3 sec.

void application_task ( )
{
    thermo20_start_conversion( );
    Delay_ms( 100 );
    
    temperature = thermo20_get_temperature( );
    
    FloatToStr( temperature, log_text );
    mikrobus_logWrite( "  Temperature : ", _LOG_TEXT );
    mikrobus_logWrite( log_text, _LOG_TEXT );
    mikrobus_logWrite( " C", _LOG_LINE );
    mikrobus_logWrite( "-----------------------------", _LOG_LINE );
    Delay_ms( 3000 );
}

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.
