THERMO Click

THERMO 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 : SPI type

Software Support

Example Description

This example measures temperature and then logs the results.

Example Libraries

• MikroSDK.Board
• MikroSDK.Log
• Click.Thermo

Example Key Functions

• thermo_cfg_setup Config Object Initialization function.

void thermo_cfg_setup ( thermo_cfg_t *cfg );

• thermo_init Initialization function.

err_t thermo_init ( thermo_t *ctx, thermo_cfg_t *cfg );

• thermo_get_temperature Function gets thermocouple temperature data.

float thermo_get_temperature ( thermo_t* ctx );

• thermo_check_fault Function checks fault states of MAX31855 sensor on Thermo Click board.

uint8_t thermo_check_fault ( thermo_t* ctx );

• thermo_read_data Function reads the 32-bit of data from the sensor.

uint32_t thermo_read_data ( thermo_t* ctx );

Application Init

Initializes driver and start write log.

void application_init ( void )
{
    log_cfg_t log_cfg;
    thermo_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 ----" );

    thermo_cfg_setup( &cfg );
    THERMO_MAP_MIKROBUS( cfg, MIKROBUS_1 );
    thermo_init( &thermo, &cfg );

    if ( thermo_check_fault( &thermo ) )
    {
        display_error_msg();
    }
    else
    {
        log_printf( &logger, "Status OK\r\n" );
    }

}

Application Task

Temperature measured by the thermocouple is converter and the results are logged.

void application_task ( void )
{
    temperature = thermo_get_temperature( &thermo );

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

}

Note

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.
