Click library

  • Author : MikroE Team
  • Date : Dec 2019.
  • Type : I2C type

Software Support

We provide a library for the Thermostat 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 form compilers IDE(recommended way), or downloaded from our LibStock, or found on mikroE github account.

Library Description

This library contains API for Thermostat Click driver.

Standard key functions :

  • Config Object Initialization function.

    void thermostat_cfg_setup ( thermostat_cfg_t *cfg );

  • Initialization function.

    THERMOSTAT_RETVAL thermostat_init ( thermostat_t ctx, thermostat_cfg_t cfg );

Example key functions :

  • Generic read 16-bit data function.

    uint16_t thermostat_read_data( thermostat_t *ctx, uint8_t reg_address );

  • Get temperature in degrees Celsius.

    float thermostat_get_temperature( thermostat_t *ctx );

  • Convert temperature in degrees Celsius to Fahrenheit.

    float thermostat_convert_fahrenheit( thermostat_t *ctx, float temp_celsius );

  • Set configuration function.

    void thermostat_set_configuration( thermostat_t *ctx, uint16_t config_value );

  • Set temperature hysterezis function

    void thermostat_set_temp_hyst( thermostat_t *ctx, int8_t temp_hyst );

  • Set referent temperature function.

    void thermostat_set_temp_ref( thermostat_t *ctx, int8_t temp_ref );

  • Soft reset function.

    void thermostat_soft_reset( thermostat_t *ctx );

  • Set on thermal switch function

    void thermostat_switch_on( thermostat_t *ctx );

  • Set off thermal switch function

    void thermostat_switch_off( thermostat_t *ctx );

  • Thermostat enabled function.

    void thermostat_enable( thermostat_t *ctx );

  • Thermostat disabled function.

    void thermostat_disable( thermostat_t *ctx );

Examples Description

This application regulates value of temperature.

The demo application is composed of two sections :

Application Init

Initialization driver enable's - I2C, soft reset sesnor, set default configuration and start write log.


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

    //  Click initialization.

    thermostat_cfg_setup( &cfg );
    THERMOSTAT_MAP_MIKROBUS( cfg, MIKROBUS_1 );
    thermostat_init( &thermostat, &cfg );

    thermostat_soft_reset( &thermostat );
    Delay_ms ( 100 );
    log_printf( &logger, "     Configuration    \r\n");

    thermostat_set_configuration( &thermostat, THERMOSTAT_DEFAULT_CONFIG );
    Delay_ms ( 100 );
    log_printf( &logger, "----------------------\r\n" );
}

Application Task

This is a example which demonstrates the use of Thermostat Click board.


void application_task ( void )
{
    float temperature;
    float limit_max = 25.0;
    float limit_min = 15.0;

    temperature = thermostat_get_temperature( &thermostat );

    log_printf( &logger, " Temperature : %.2f \r\n", temperature );

    if ( ( temperature < limit_max ) && ( temperature > limit_min ) )
    { 
        thermostat_switch_on(  &thermostat  );
    }
    else
    {   
        thermostat_switch_off(  &thermostat  );
        log_printf( &logger, "----------------------\r\n" );
    }
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
} 

The full application code, and ready to use projects can be installed directly form compilers IDE(recommneded) or found on LibStock page or mikroE GitHub accaunt.

Other mikroE Libraries used in the example:

  • MikroSDK.Board
  • MikroSDK.Log
  • Click.Thermostat

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. The terminal available in all Mikroelektronika compilers, or any other terminal application of your choice, can be used to read the message.

UT-S 7-SEG R Click

7-segment LED display is the most commonly used type of display to represent changing numerical values. The principle is very simple - seven LED segments are positioned in a certain shape and by turning specific segments on or off, the shape that resembles a specific number is lit. This method of displaying numbers was first used in the beginning of the 20th century, but after the invention of the LED in ‘70, it is the most commonly used method to display numbers. It utilizes a fairly simple and cheap design with the numbers clearly visible.
