Thermo 20 Click

Thermo 20 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.

Example Description

This example showcases the ability of Thermo 20 Click board to read it's serial number. It can read themperature and measure from -40degC to 120degC.

Example Libraries

• MikroSDK.Board
• MikroSDK.Log
• Click.Thermo20

Example Key Functions

• thermo20_cfg_setup Config Object Initialization function.

void thermo20_cfg_setup ( thermo20_cfg_t *cfg );

• thermo20_init Initialization function.

err_t thermo20_init ( thermo20_t *ctx, thermo20_cfg_t *cfg );

• thermo20_default_cfg Click Default Configuration function.

err_t thermo20_default_cfg ( thermo20_t *ctx );

• thermo20_set_cmd Send command function.

err_t thermo20_set_cmd ( thermo20_t *ctx, uint8_t cmd );

• thermo20_start_conversion Start conversion function.

void thermo20_start_conversion ( thermo20_t *ctx );

• thermo20_get_temperature Get temperature data function.

float thermo20_get_temperature ( thermo20_t *ctx );

Application Init

Initialization communication modules(I2C, UART). Resets device and read Serial Number.

void application_init ( void ) 
{
    log_cfg_t log_cfg;  /**< Logger config object. */
    thermo20_cfg_t thermo20_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.
    thermo20_cfg_setup( &thermo20_cfg );
    THERMO20_MAP_MIKROBUS( thermo20_cfg, MIKROBUS_1 );
    err_t init_flag = thermo20_init( &thermo20, &thermo20_cfg );
    if ( I2C_MASTER_ERROR == init_flag ) 
    {
        log_error( &logger, " Application Init Error. " );
        log_info( &logger, " Please, run program again... " );

        for ( ; ; );
    }

    thermo20_default_cfg ( &thermo20 );
    
    uint32_t ser_numb = thermo20_get_serial_number( &thermo20 );
    log_printf( &logger, " > Serial Number: %lu\r\n", ser_numb );
    
    log_info( &logger, " Application Task " );
}

Application Task

In span of ~ 1000ms it sends command for adc conversion of temperature, reads ADC value, and calculates temperature in degrees C.

void application_task ( void ) 
{
    thermo20_start_conversion( &thermo20 );
    float temperature = thermo20_get_temperature( &thermo20 );
    log_printf( &logger, " > Temperature[deg C]: %.2f\r\n", temperature );
    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.
