| 14 | +### Software Support |
| 15 | + |
| 16 | +We provide a library for the Temp_Hum_9 Click on our [LibStock](https://libstock.mikroe.com/projects/view/2671/temp-hum-9-click) |
| 17 | +page, as well as a demo application (example), developed using MikroElektronika |
| 18 | +[compilers](http://shop.mikroe.com/compilers). The demo can run on all the main |
| 19 | +MikroElektronika [development boards](http://shop.mikroe.com/development-boards). |
| 20 | + |
| 21 | +**Library Description** |
| 22 | + |
| 23 | + Library contains |
| 24 | + |
| 25 | +Key functions : |
| 26 | + |
| 27 | +- ``` void temphum9_readRegister( uint16_t registerAddress_, uint8_t nData_, uint16_t *registerBuffer_ ) ``` - reads one or two 16-bit registers |
| 28 | +- ``` void temphum9_sendCommand( uint16_t command_ ) ``` - issues (sends) command to device |
| 29 | +- ``` void temhum9_getTemperatureAndHumidity( uint8_t mode_, float *measurementData) ``` - performs temperature and relative humidity measurement and calculates temperature and relative humidity |
| 30 | + |
| 31 | +**Examples Description** |
| 32 | + |
| 33 | +Description : |
| 34 | + |
| 35 | +The application is composed of three sections : |
| 36 | + |
| 37 | +- System Initialization - Initializes LOG and I2C |
| 38 | +- Application Initialization - Initializes I2C driver and sends SLEEP and WAKEUP dommands |
| 39 | +- Application Task - Performs simultaneous temperature and relative humidity measurements and logs both values |
| 40 | + |
| 41 | + |
| 42 | +```.c |
| 43 | + |
| 44 | +void applicationTask( ) |
| 45 | +{ |
| 46 | + mikrobus_logWrite( " ", _LOG_LINE ); |
| 47 | + |
| 48 | + temhum9_getTemperatureAndHumidity( _TEMPHUM9_NORMAL_MODE, &measurementData[0] ); |
| 49 | + |
| 50 | + FloatToStr( measurementData[0], text ); |
| 51 | + mikrobus_logWrite( "> > > Temperature : ", _LOG_TEXT ); |
| 52 | + mikrobus_logWrite( text, _LOG_TEXT ); |
| 53 | + mikrobus_logWrite( " C", _LOG_LINE ); |
| 54 | + |
| 55 | + FloatToStr( measurementData[1], text ); |
| 56 | + mikrobus_logWrite( "> > > Relative humidity : ", _LOG_TEXT ); |
| 57 | + mikrobus_logWrite( text, _LOG_TEXT ); |
| 58 | + mikrobus_logWrite( " %", _LOG_LINE ); |
| 59 | + |
| 60 | + mikrobus_logWrite( " ", _LOG_LINE ); |
| 61 | + |
| 62 | + Delay_ms(1000); |
| 63 | +} |
| 64 | + |
| 65 | +``` |
| 66 | +
|
| 67 | +
|
| 68 | +The full application code, and ready to use projects can be found on our |
| 69 | +[LibStock](https://libstock.mikroe.com/projects/view/2671/temp-hum-9-click) page. |

|
| 71 | +Other mikroE Libraries used in the example: |
| 72 | +
|
| 73 | +- I2C |
| 74 | +- UART |
| 75 | +- Conversions |
| 76 | +
|
| 77 | +**Additional notes and informations** |
| 78 | +
|
| 79 | +Depending on the development board you are using, you may need |
| 80 | +[USB UART click](http://shop.mikroe.com/usb-uart-click), |
| 81 | +[USB UART 2 Click](http://shop.mikroe.com/usb-uart-2-click) or |
| 82 | +[RS232 Click](http://shop.mikroe.com/rs232-click) to connect to your PC, for |
| 83 | +development systems with no UART to USB interface available on the board. The |
| 84 | +terminal available in all Mikroelektronika |
| 85 | +[compilers](http://shop.mikroe.com/compilers), or any other terminal application |
| 86 | +of your choice, can be used to read the message. |
