Temp Hum 6 Click

TempHum 6 Click demo application is developed using the NECTO Studio, ensuring compatibility with mikroSDK's open-source libraries and tools. Designed for plug-and-play implementation and testing, the demo is fully compatible with all development, starter, and mikromedia boards featuring a mikroBUS™ socket.

Click Library

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

Software Support

Example Description

This application emasures temperature and humidity.

Example Libraries

  • MikroSDK.Board
  • MikroSDK.Log
  • Click.TempHum6

Example Key Functions

  • temphum6_cfg_setup Config Object Initialization function.
void temphum6_cfg_setup ( temphum6_cfg_t *cfg );
  • temphum6_init Initialization function.
err_t temphum6_init ( temphum6_t *ctx, temphum6_cfg_t *cfg );
  • temphum6_default_cfg Click Default Configuration function.
void temphum6_default_cfg ( temphum6_t *ctx );
  • temphum6_read_temperature This function returns read Temperature data.
float temphum6_read_temperature ( temphum6_t *ctx, uint8_t temp_in );
  • temphum6_read_relative_huminidy This function returns read relative Humidity data.
float temphum6_read_relative_huminidy ( temphum6_t *ctx );
  • temphum6_get_part_id This function returns the device part id.
uint16_t temphum6_get_part_id ( temphum6_t *ctx );

Application Init

Initialization driver init and reset device and read Part ID

void application_init ( void )
{
    log_cfg_t log_cfg;
    temphum6_cfg_t cfg;
    uint16_t part_id;

    /** 
     * 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.

    temphum6_cfg_setup( &cfg );
    TEMPHUM6_MAP_MIKROBUS( cfg, MIKROBUS_1 );
    temphum6_init( &temphum6, &cfg );

    temphum6_reset( &temphum6 );
    
    part_id = temphum6_get_part_id( &temphum6 );
    if ( part_id == TEMPHUM6_PART_ID )
    {
        log_printf( &logger, "Device OK - read ID is OK" );
    }
    else
    {
        log_printf( &logger, "Device ERROR - read ID is NOT OK" );
    }
}

Application Task

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

void application_task ( void )
{
    //  Task implementation.

    float temp;
    float hum;

    temp = temphum6_read_temperature( &temphum6, TEMPHUM6_TEMP_IN_CELSIUS );
    log_printf( &logger, "Temperature is %f C\r\n");
    
    hum = temphum6_read_relative_huminidy( &temphum6 );
    log_printf( &logger, "Huminidy is %f %%RH\r\n");
    
    log_printf( &logger, "------------------\r\n");
    Delay_ms ( 1000 );
}

Application Output

This Click board can be interfaced and monitored in two ways:

  • Application Output - Use the "Application Output" window in Debug mode for real-time data monitoring. Set it up properly by following this tutorial.
  • UART Terminal - Monitor data via the UART Terminal using a USB to UART converter. For detailed instructions, check out this tutorial.

Additional Notes and Information

The complete application code and a ready-to-use project are available through the NECTO Studio Package Manager for direct installation in the NECTO Studio. The application code can also be found on the MIKROE GitHub account.
