Library Description
The library contains basic functions for reading temperature and pressure. The user has the ability to set the configuration of the measurement module.
Key functions:
float pressure10_get_temperature ( void )
- Get Temperature data in Cfloat pressure10_get_pressure ( void )
- Get Pressure data in %RHvoid pressure10_control_cfg ( uint8_t ctrl_reg, uint8_t wr_data )
- Set the configuration in the control registersExamples description
The application is composed of three sections :
void application_task( )
{
float temperature;
float pressure;
char demo_text[ 20 ];
pressure = pressure10_get_pressure( );
temperature = pressure10_get_temperature( );
FloatToStr( temperature, demo_text );
mikrobus_logwrite( ">> Temperature: ", _LOG_TEXT );
mikrobus_logwrite( demo_text, _LOG_TEXT );
mikrobus_logWrite( " C", _LOG_LINE );
FloatToStr( pressure, demo_text );
mikrobus_logwrite( ">> Pressure: ", _LOG_TEXT );
mikrobus_logwrite( demo_text, _LOG_TEXT );
mikrobus_logWrite( " %RH", _LOG_LINE );
mikrobus_logwrite( "-----------------------", _LOG_LINE );
Delay_ms( 1500 );
}

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.
