Click library

  • Author : Petar Suknjaja
  • Date : Dec 2019.
  • Type : I2C type

Software Support

We provide a library for the TempHum3 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 TempHum3 Click driver.

Standard key functions :

  • Config Object Initialization function.

    void temphum3_cfg_setup ( temphum3_cfg_t *cfg );

  • Initialization function.

    TEMPHUM3_RETVAL temphum3_init ( temphum3_t *ctx, temphum3_cfg_t *cfg );

  • Click Default Configuration function.

    void temphum3_default_cfg ( temphum3_t *ctx );

Example key functions :

  • Get temperature value

    float temphum3_get_temperature ( temphum3_t *ctx );

  • Get humidity value

    float temphum3_get_huminidy ( temphum3_t *ctx );

  • Get maximum temperature value

    float temphum3_get_max_hum ( temphum3_t *ctx );

Examples Description

This example gets the values of humidity and temperature. It uses predefined minimum and maximum offset values for temperature and humidity.

The demo application is composed of two sections :

Application Init

Initializes the module and sets predefined configuration values to the sensor.

void application_init ( void )
{
log_cfg_t log_cfg;
LOG_MAP_USB_UART( log_cfg );
log_init( &logger, &log_cfg );
log_info( &logger, "---- Application Init ----" );
// Click initialization.
TEMPHUM3_MAP_MIKROBUS( cfg, MIKROBUS_1 );
temphum3_init( &temphum3, &cfg );
log_info( &logger, "---- Init done -----" );
temphum3_default_cfg( &temphum3 );
log_info( &logger, "--- Settings Temp&Hum done---" );
}

Application Task

Reads the temperature and huminidy and logs to the USBUART every 500 ms.

void application_task ( void )
{
float temperature;
float humidity;
// Task implementation.
temperature = temphum3_get_temperature( &temphum3 );
log_printf( &logger, " Temperature : %f C \r\n", temperature );
humidity = temphum3_get_humidity( &temphum3 );
log_printf( &logger, " Humidity : %f %% \r\n", humidity );
Delay_ms( 500 );
}

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.TempHum3

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.
