Thermo J Click

Thermo J 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.

Application Init

Initialization device.

void application_init ( void )
{
    log_cfg_t log_cfg;
    thermoj_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.

    thermoj_cfg_setup( &cfg );
    THERMOJ_MAP_MIKROBUS( cfg, MIKROBUS_1 );
    thermoj_init( &thermoj, &cfg );

    log_printf( &logger, "---------------------------\r\n" );
    log_printf( &logger, "      Thermo J  Click      \r\n" );
    log_printf( &logger, "---------------------------\r\n" );
    
    log_printf( &logger, " Set thermocouple type:  J \r\n" );

    thermoj_set_thermocouple_type( &thermoj, THERMOJ_THERMOCOUPLE_TYPE_J );
    Delay_ms ( 1000 );

    log_printf( &logger, "---------------------------\r\n" );
}

Application Task

This is a example which demonstrates the use of Thermo J Click board. Measured temperature data from the MCP9600 sensor on Thermo J Click board. Results are being sent to the Usart Terminal where you can track their changes.

void application_task ( void )
{
    check_data_ready =  thermoj_check_data_ready( &thermoj );

    if ( check_data_ready )
    {
        temperature = thermoj_get_temperature( &thermoj );

        log_printf( &logger, " Temperature : %.2f Celsius\r\n", temperature );
        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.
