Temp&Hum 7 Click

TempHum 7 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 : Nov 2019.
  • Type : I2C type

Software Support

Example Description

This application measurement temperature and humidity data.

Example Libraries

  • MikroSDK.Board
  • MikroSDK.Log
  • Click.TempHum7

Example Key Functions

  • temphum7_cfg_setup Config Object Initialization function.
void temphum7_cfg_setup ( temphum7_cfg_t *cfg );
  • temphum7_init Initialization function.
err_t temphum7_init ( temphum7_t *ctx, temphum7_cfg_t *cfg );
  • temphum7_default_cfg Click Default Configuration function.
void temphum7_default_cfg ( temphum7_t *ctx );
  • temphum7_get_relative_humidity Relative humidity.
float temphum7_get_relative_humidity ( temphum7_t *ctx, uint8_t mode_data );
  • temphum7_get_temperature Get temerature.
float temphum7_get_temperature ( temphum7_t *ctx, uint8_t mode_data );
  • temphum7_get_firmware_revision Firmware revision.
uint8_t temphum7_get_firmware_revision ( temphum7_t *ctx );

Application Init

Initializes device and logger module and sets default configuration for measurements.

void application_init ( void )
{
    log_cfg_t log_cfg;
    temphum7_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.

    temphum7_cfg_setup ( &cfg );
    TEMPHUM7_MAP_MIKROBUS ( cfg, MIKROBUS_1 );
    temphum7_init ( &temphum7, &cfg );

    temphum7_default_cfg( &temphum7 );
}

Application Task

Calculates and Logs temperature and relative humidity

void application_task ( void )
{
    
    temperature = temphum7_get_temperature ( &temphum7, TEMPHUM7_HOLD_MASTER_MODE );
    mikrobus_printf ( "-> Temperature: %f C/r/n", temperature );

    relative_humidity = temphum7_get_relative_humidity ( &temphum7, TEMPHUM7_HOLD_MASTER_MODE );
    mikrobus_printf ( "-> Relative humidity: %f %%RH/r/n ", relative_humidity );

    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.
