• Click.TempHum2

Example Key Functions

• temphum2_cfg_setup Config Object Initialization function.

void temphum2_cfg_setup ( temphum2_cfg_t *cfg );

• temphum2_init Initialization function.

err_t temphum2_init ( temphum2_t *ctx, temphum2_cfg_t *cfg );

• temphum2_default_cfg Click Default Configuration function.

void temphum2_default_cfg ( temphum2_t *ctx );

• temhum2_get_eletronic_id This function for reads Eletronic ID.

void temhum2_get_eletronic_id ( temphum2_t *ctx, uint8_t *electronic_id );

• temphum2_set_mode Functions for set measurement mode.

void temphum2_set_mode ( uint8_t select_mode, uint8_t speed_mode );

• temphum2_get_measurement Functions for mesurement.

void temphum2_get_measurement ( temphum2_t *ctx, float *data_buffer );

Application Init

Initializes driver init, set work mode and Heater

void application_init ( void )
{
    log_cfg_t log_cfg;
    temphum2_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.

    temphum2_cfg_setup( &cfg );
    TEMPHUM2_MAP_MIKROBUS( cfg, MIKROBUS_1 );
    temphum2_init( &temphum2, &cfg );

    temphum2_default_cfg( &temphum2 );
}

Application Task

Reads temperature and humidity and logs values on usbuart for every 500ms.

void application_task ( void )
{
    float data_buffer[ 2 ];
    
    temphum2_get_measurement( &temphum2, &data_buffer[ 0 ] );
    
    log_printf( &logger, " --- Temperature : %.2f C \r\n ", data_buffer[ 0 ] );
    log_printf( &logger, " --- Humidity : %.2f RH \r\n ", data_buffer[ 1 ] );
    
    Delay_ms ( 500 );
}

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.
