Click library

  • Author : Stefan Ilic
  • Date : Nov 2022.
  • Type : I2C type

Software Support

We provide a library for the Thermo 27 Click as well as a demo application (example), developed using MikroElektronika compilers. The demo can run on all the main MikroElektronika development boards.

Package can be downloaded/installed directly from NECTO Studio Package Manager(recommended way), downloaded from our LibStock™ or found on Mikroe github account.

Library Description

This library contains API for Thermo 27 Click driver.

Standard key functions :

  • thermo27_cfg_setup Config Object Initialization function.

    void thermo27_cfg_setup ( thermo27_cfg_t *cfg );
  • thermo27_init Initialization function.

    err_t thermo27_init ( thermo27_t *ctx, thermo27_cfg_t *cfg );
  • thermo27_default_cfg Click Default Configuration function.

    err_t thermo27_default_cfg ( thermo27_t *ctx );

Example key functions :

  • thermo27_write_register Thermo 27 register writing function.

    err_t thermo27_write_register ( thermo27_t *ctx, uint8_t reg, uint16_t data_in );
  • thermo27_get_device_id Thermo 27 get device id function.

    err_t thermo27_get_device_id ( thermo27_t *ctx, uint16_t *device_id );
  • thermo27_read_temp Thermo 27 get read temperature function.

    err_t thermo27_read_temp ( thermo27_t *ctx, float *temp_out );

Example Description

This example demonstrates the use of Thermo 27 Click board by reading and displaying the temperature measurements.

The demo application is composed of two sections :

Application Init

Initializes the driver and reads the device id, and after that resets the device and performs default configuration.


void application_init ( void ) 
{
    log_cfg_t log_cfg;  /**< Logger config object. */
    thermo27_cfg_t thermo27_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.
    thermo27_cfg_setup( &thermo27_cfg );
    THERMO27_MAP_MIKROBUS( thermo27_cfg, MIKROBUS_1 );
    if ( I2C_MASTER_ERROR == thermo27_init( &thermo27, &thermo27_cfg ) ) 
    {
        log_error( &logger, " Communication init." );
        for ( ; ; );
    }

    uint16_t device_id;
    thermo27_get_device_id( &thermo27, &device_id );
    if ( THERMO27_DEVICE_ID != device_id )
    {
        log_error( &logger, " Communication error." );
        for ( ; ; );
    }

    if ( THERMO27_ERROR == thermo27_default_cfg( &thermo27 ) )
    {
        log_error( &logger, " Default configuration." );
        for ( ; ; );
    }

    log_info( &logger, " Application Task " );
    log_printf( &logger, " ======================= \r\n");
}

Application Task

Reads the temperature measurement in degrees Celsius and displays the results on the USB UART at a rate of once per second.


void application_task ( void ) 
{
    float temperature;
    uint8_t status;

    thermo27_get_alert_reg( &thermo27, &status );
    if ( THERMO27_DATA_READY_FLAG & status )
    {
        thermo27_read_temp( &thermo27, &temperature );
        log_printf( &logger, " Temperature: %f degC \r\n", temperature );
        log_printf( &logger, " ======================= \r\n");
    }
}

The full application code, and ready to use projects can be installed directly from NECTO Studio Package Manager(recommended way), downloaded from our LibStock™ or found on Mikroe github account.

Other Mikroe Libraries used in the example:

  • MikroSDK.Board
  • MikroSDK.Log
  • Click.Thermo27

Additional notes and informations

Depending on the development board you are using, you may need USB UART Click, USB UART 2 Click or RS232 Click to connect to your PC, for development systems with no UART to USB interface available on the board. UART terminal is available in all MikroElektronika compilers.

Shutter Click is an adapter Click board™ used to implement an automated capturing feature. This Click board™ features one 3.5mm jack connector suitable for a camera connection with which the frame is captured. By combining two mikroBUS™ pins and the VO617A, a high-reliability phototransistor from Vishay Semiconductors used as a camera activation switch, activating the camera's Auto-Focus and the action of taking pictures is realized. This Click board™ allows you to expressly capture frames in a simple way for various types of photographic and security applications to capture those parts you need.
