Thermo K 3 Click

Thermo K 3 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.

• Date : Apr 2023.
• Type : SPI type

Software Support

Example Description

This example demonstrates the use of Thermo K 3 Click board by reading and displaying the temperature measurements.

Example Libraries

• MikroSDK.Board
• MikroSDK.Log
• Click.ThermoK3

Example Key Functions

• thermok3_cfg_setup Config Object Initialization function.

void thermok3_cfg_setup ( thermok3_cfg_t *cfg );

• thermok3_init Initialization function.

err_t thermok3_init ( thermok3_t *ctx, thermok3_cfg_t *cfg );

• thermok3_read_data This function reads a raw data output by using the SPI serial interface.

err_t thermok3_read_data ( thermok3_t *ctx, uint16_t *data_out );

• thermok3_read_temperature This function reads a raw data output and converts it to temperature in Celsius.

err_t thermok3_read_temperature ( thermok3_t *ctx, float *temperature );

Application Init

Initializes the driver and logger.

void application_init ( void )
{
    log_cfg_t log_cfg;  /**< Logger config object. */
    thermok3_cfg_t thermok3_cfg;  /**< Click config object. */

    /** 
     * 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.
    thermok3_cfg_setup( &thermok3_cfg );
    THERMOK3_MAP_MIKROBUS( thermok3_cfg, MIKROBUS_1 );
    if ( SPI_MASTER_ERROR == thermok3_init( &thermok3, &thermok3_cfg ) )
    {
        log_error( &logger, " Communication init." );
        for ( ; ; );
    }
    
    log_info( &logger, " Application Task " );
}

Application Task

Reads the temperature measurement in Celsius and displays the results on the USB UART approximately once per second. If there's no thermocouple type-K probe inserted an appropriate message will be displayed instead.

void application_task ( void )
{
    float temperature = 0;
    err_t error_flag = thermok3_read_temperature ( &thermok3, &temperature );
    if ( THERMOK3_OK == error_flag )
    {
        log_printf( &logger, " Temperature: %.2f C\r\n\n", temperature );
    }
    else if ( THERMOK3_OPEN_THERMOCOUPLE == error_flag )
    {
        log_printf( &logger, " NO thermocouple input\r\n\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.
