Thermo 21 Click

Thermo 21 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.

• Type : SPI type

Software Support

Example Description

This example application showcases ability of the Click board to read temperature data.

Example Libraries

• MikroSDK.Board
• MikroSDK.Log
• Click.Thermo21

Example Key Functions

• thermo21_cfg_setup Config Object Initialization function.

void thermo21_cfg_setup ( thermo21_cfg_t *cfg );

• thermo21_init Initialization function.

err_t thermo21_init ( thermo21_t *ctx, thermo21_cfg_t *cfg );

• thermo21_temperature_read Temperature reading function.

err_t thermo21_temperature_read ( thermo21_t *ctx, float *data_out );

• thermo21_generic_read Data reading function.

err_t thermo21_generic_read ( thermo21_t *ctx, uint8_t *data_out, uint8_t len );

Application Init

Initialization of communication modules(SPI, UART).

void application_init ( void )
{
    log_cfg_t log_cfg;  /**< Logger config object. */
    thermo21_cfg_t thermo21_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.
    thermo21_cfg_setup( &thermo21_cfg );
    THERMO21_MAP_MIKROBUS( thermo21_cfg, MIKROBUS_1 );
    if ( SPI_MASTER_ERROR == thermo21_init( &thermo21, &thermo21_cfg ) )
    {
        log_error( &logger, " Communication init." );
        for ( ; ; );
    }
    
    log_info( &logger, " Application Task " );
}

Application Task

Read and log temperautre every half second.

void application_task ( void )
{
    float temperature = 0;
    if ( !thermo21_temperature_read( &thermo21, &temperature ) )
    {
        log_printf( &logger, " > Temperature[degC]: %.2f\r\n", temperature );
    }
    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.
