Click library

  • Author : MikroE Team
  • Date : Dec 2019.
  • Type : I2C type

Software Support

We provide a library for the TempHum9 Click as well as a demo application (example), developed using MikroElektronika compilers. The demo can run on all the main MikroElektronika development boards.

Package can be downloaded/installed directly form compilers IDE(recommended way), or downloaded from our LibStock, or found on mikroE github account.

Library Description

This library contains API for TempHum9 Click driver.

Standard key functions :

  • temphum9_cfg_setup Config Object Initialization function.

    void temphum9_cfg_setup ( temphum9_cfg_t *cfg ); 
  • temphum9_init Initialization function.

    err_t temphum9_init ( temphum9_t *ctx, temphum9_cfg_t *cfg );

Example key functions :

  • temphum9_get_temperature Calculating temperature

    float temphum9_get_temperature ( temphum9_t *ctx, uint8_t data_mode );
  • temphum9_get_humidity Calculating relative humidity

    float temphum9_get_humidity ( temphum9_t *ctx, uint8_t data_mode );
  • temhum9_get_data Calculating temperature and relative humidity

    void temhum9_get_data ( temphum9_t *ctx, uint8_t data_mode, float *temp, float *hum );

Example Description

This example demonstrates the use of TempHum 9 Click board by reading and displaying the temperature and humidity measurement results.

The demo application is composed of two sections :

Application Init

Initializes I2C driver and sends SLEEP and WAKEUP commands.


void application_init ( void )
{
    log_cfg_t log_cfg;
    temphum9_cfg_t cfg;

    /** 
     * Logger initialization.
     * Default baud rate: 115200
     * Default log level: LOG_LEVEL_DEBUG
     * @note If USB_UART_RX and USB_UART_TX 
     * are defined as HAL_PIN_NC, you will 
     * need to define them manually for log to work. 
     * See @b LOG_MAP_USB_UART macro definition for detailed explanation.
     */
    LOG_MAP_USB_UART( log_cfg );
    log_init( &logger, &log_cfg );
    log_info( &logger, " Application Init " );

    //  Click initialization.
    temphum9_cfg_setup( &cfg );
    TEMPHUM9_MAP_MIKROBUS( cfg, MIKROBUS_1 );
    temphum9_init( &temphum9, &cfg );
    Delay_ms ( 100 );

    temphum9_send_command( &temphum9, TEMPHUM9_SLEEP );
    Delay_ms ( 500 );
    temphum9_send_command( &temphum9, TEMPHUM9_WAKEUP );
    Delay_ms ( 500 );

    log_info( &logger, " Application Task " );
}

Application Task

Performs simultaneous temperature and relative humidity measurements and logs both values on the USB UART once per second.


void application_task( )
{
    float temperature = 0;
    float humidity = 0;

    temhum9_get_data ( &temphum9, TEMPHUM9_NORMAL_MODE, &temperature, &humidity );

    log_printf( &logger, " Temperature: %.2f degC\r\n", temperature );

    log_printf( &logger, " Relative humidity: %.2f %%\r\n", humidity );

    log_printf( &logger, "-----------------------------\r\n" );

    Delay_ms ( 1000 );
}

The full application code, and ready to use projects can be installed directly form compilers IDE(recommneded) or found on LibStock page or mikroE GitHub accaunt.

Other mikroE Libraries used in the example:

  • MikroSDK.Board
  • MikroSDK.Log
  • Click.TempHum9

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.
