Click library

  • Author : Mikroe Team
  • Date : Jul 2021.
  • Type : I2C type

Software Support

We provide a library for the Thermo20 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 Thermo20 Click driver.

Standard 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 );

Example key functions :

  • 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 );

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.

The demo application is composed of two sections :

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 );
}

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.Thermo20

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.
