Library Description
The library covers all the necessary functions to control Temp&Hum 14 Click board™. Library performs a standard I2C interface communication.
Key functions:
void temphum14_set_conversion ( uint8_t hum_osr, uint8_t temp_osr )
- Set conversion function.void temphum14_get_diagnostic ( temphum14_diagn_t *diag_data )
- Get diagnostic status function.void temphum14_get_temp_and_hum ( float *temp, float *hum )
- Get temperature and humidity data function.Examples description
The application is composed of three sections :
void application_task ( )
{
temphum14_set_conversion( TEMPHUM14_CONVERSION_HUM_OSR_0_020,
TEMPHUM14_CONVERSION_TEMP_0_040 );
Delay_ms( 10 );
temphum14_get_temp_and_hum( &temperature, &humidity );
Delay_ms( 10 );
FloatToStr( temperature, log_text );
mikrobus_logWrite( " Temperature : ", _LOG_TEXT );
mikrobus_logWrite( log_text, _LOG_TEXT );
mikrobus_logWrite( " C", _LOG_LINE );
FloatToStr( humidity, log_text );
mikrobus_logWrite( " Humidity : ", _LOG_TEXT );
mikrobus_logWrite( log_text, _LOG_TEXT );
mikrobus_logWrite( " %", _LOG_LINE );
mikrobus_logWrite( "-----------------------------", _LOG_LINE );
Delay_ms( 3000 );

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.
