Click library

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

Software Support

We provide a library for the TempHum10 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 TempHum10 Click driver.

Standard key functions :

• Config Object Initialization function.

  ‍void temphum10_cfg_setup ( temphum10_cfg_t *cfg );

  - Initialization function.

  ‍TEMPHUM10_RETVAL temphum10_init ( temphum10_t *ctx, temphum10_cfg_t *cfg );

  Example key functions :

• Functions for read Temperature data

  ‍float temphum10_get_temperature ( temphum10_t *ctx );

  - Functions for sets Device mode

  ‍void temphum10_set_device_mode ( temphum10_t *ctx, uint8_t mode );

• Functions for repeat measurement

  ‍void temphum10_repeat_measurement ( temphum10_t *ctx, uint8_t average );

  Examples Description

‍This application measures temperature and humidity.

The demo application is composed of two sections :

Application Init

‍Initialization driver init and sets device mode

void application_init ( void )
{
    log_cfg_t log_cfg;
    temphum10_cfg_t cfg;
    uint8_t tmp;
 
    LOG_MAP_USB_UART( log_cfg );
    log_init( &logger, &log_cfg );
    log_info( &logger, "---- Application Init ----" );
 
    //  Click initialization.
 
    temphum10_cfg_setup( &cfg );
    TEMPHUM10_MAP_MIKROBUS( cfg, MIKROBUS_1 );
    temphum10_init( &temphum10, &cfg );
 
    log_info( &logger, "---- Device config ----" );
    
    temphum10_set_device_mode( &temphum10, TEMPHUM10_MODE_STANDBY );
    Delay_ms ( 100 );
    
    tmp = TEMPHUM10_RST_NORMAL_OPERATION;
    temphum10_generic_write( &temphum10, TEMPHUM10_REG_DEVICE_RESET, &tmp, 1 );
    Delay_ms ( 100 );
    log_info( &logger, "---- Device calibration ----" );
    tmp = TEMPHUM10_AM_TIMES_AVERAGE_MODE_8 | TEMPHUM10_AM_TEMP_AVERAGE_MODE_TIMES_16;
    temphum10_repeat_measurement( &temphum10, tmp );
    temphum10_get_temperature( &temphum10 );
    temphum10_get_humidity( &temphum10 );
    Delay_ms ( 100 );
    temphum10_repeat_measurement( &temphum10, tmp );
    temphum10_get_temperature( &temphum10 );
    temphum10_get_humidity( &temphum10 );
    log_info( &logger, "---- Application Task ----" );
}

Application Task

‍Reads Temperature and Humidity data and logs this data to USBUART every 1 sec.

void application_task ( )
{
    float temperature = 0;
    float humidity = 0;
    uint8_t tmp;
    
    tmp = TEMPHUM10_AM_TIMES_AVERAGE_MODE_8 | TEMPHUM10_AM_TEMP_AVERAGE_MODE_TIMES_16;
    temphum10_repeat_measurement( &temphum10, tmp );
    temperature = temphum10_get_temperature( &temphum10 );
    humidity = temphum10_get_humidity( &temphum10 );
    
    log_printf( &logger, " Temperature : %.2f \r\n", temperature );
    log_printf( &logger, " 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.TempHum10

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.
