Click library

• Author : Katarina Perendic
• Date : okt 2019.
• Type : I2C type

Software Support

We provide a library for the Thermo6 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 Thermo6 Click driver.

Standard key functions :

• Config Object Initialization function.

  void thermo6_cfg_setup ( thermo6_cfg_t *cfg );

• Initialization function.

  THERMO6_RETVAL thermo6_init ( thermo6_t ctx, thermo6_cfg_t cfg );

• Click Default Configuration function.

  void thermo6_default_cfg ( thermo6_t *ctx );

Example key functions :

• Temperature function

  float thermo6_get_temperature_data ( thermo6_t *ctx, uint8_t temp_format );

• Read over-temperature status function

  uint8_t thermo6_get_over_temp_status( thermo6_t *ctx );

• Set other register

  float thermo6_get_other_register( thermo6_t *ctx, uint8_t reg );

Examples Description

Demo application shows ambient temperature reading using Thermo 6 click.

The demo application is composed of two sections :

Application Init

Configuring clicks and log objects. Setting the click in the default configuration to start the measurement.

void application_init ( void )
{
    log_cfg_t log_cfg;
    thermo6_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.

    thermo6_cfg_setup( &cfg );
    THERMO6_MAP_MIKROBUS( cfg, MIKROBUS_1 );
    thermo6_init( &thermo6, &cfg );

    thermo6_default_cfg( &thermo6 );
    log_info( &logger, "---- Start measurement ----");
    Delay_ms ( 1000 );
}

Application Task

It measures the temperature and logs a message about the current temperature.

void application_task ( void )
{
    float temperature;

    //  Task implementation.

    temperature = thermo6_get_temperature_data( &thermo6, THERMO6_TEMP_FORMAT_CELSIUS );
    log_printf( &logger, ">> Temperature is %.3f C \r\n", temperature );

    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.Thermo6

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.
