Thermo 13 Click

Thermo 13 Click is a Click board™ equipped with the sensor IC, which can digitize temperature measurements between -30°C and +95°C so that the temperature measurement data can be processed by the host MCU.

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

Software Support

We provide a library for the Thermo13 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 Thermo13 Click driver.

Standard key functions :

• Config Object Initialization function.

  void thermo13_cfg_setup ( thermo13_cfg_t *cfg );

• Initialization function.

  THERMO13_RETVAL thermo13_init ( thermo13_t ctx, thermo13_cfg_t cfg );

• Click Default Configuration function.

  void thermo13_default_cfg ( thermo13_t *ctx );

Example key functions :

• Set temperature limit register

  void thermo13_set_temp_limit ( thermo13_t *ctx, uint8_t temp_reg, float temp );

• Get temperature register

  float thermo13_get_temp_limit ( thermo13_t *ctx, uint8_t temp_reg );

• Ambient temperature data

  float thermo13_get_ambient_temperature_data ( thermo13_t *ctx, uint8_t temp_in );

Examples Description

The application measures temperature

The demo application is composed of two sections :

Application Init

Initializes the driver init, configures the module and reads the temperature Limit LOW/HIGH values that are set.

void application_init ( void )
{
    log_cfg_t log_cfg;
    thermo13_cfg_t cfg;

    float temp_limit_low;
    float temp_limit_high;

    /** 
     * 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

    thermo13_cfg_setup( &cfg );
    THERMO13_MAP_MIKROBUS( cfg, MIKROBUS_1 );
    thermo13_init( &thermo13, &cfg );

    // Configuration 

    thermo13_configuration( &thermo13, THERMO13_CFG_CONTINUOUS_MEASUREMENT |
                            THERMO13_CFG_FAULT_QUEUE_1 |
                            THERMO13_CFG_ALERT_ACTIVE_HIGH |
                            THERMO13_CFG_INTERRUPT_IS_ACTIVE |
                            THERMO13_CFG_WAIT_TIME_X16 );


    // Temperature Register
    log_printf( &logger, " --- Temperature register data --- \r\n \r\n" );

    temp_limit_low = thermo13_get_temp_limit ( &thermo13, THERMO13_REG_TEMPERATURE_LIMIT_LOW );
    log_printf( &logger, " --- Temp - Limit LOW : %.2f C \r\n ", temp_limit_low );

    temp_limit_high = thermo13_get_temp_limit ( &thermo13, THERMO13_REG_TEMPERATURE_LIMIT_HIGH );
    log_printf( &logger, " --- Temp - Limit HIGH :  %.2f C \r\n \r\n  ", temp_limit_high );

    log_printf( &logger, " --- Ambient temperature measurement --- \r\n " );

}
}

Application Task

Reads ambient temperature data and this data logs to USBUART every 1500ms.

void application_task ( void )
{
    float temperature;

    temperature = thermo13_get_ambient_temperature_data ( &thermo13,  THERMO13_TEMP_IN_CELSIUS );

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

    log_printf( &logger, " ----------------------------\r\n" );

    Delay_ms ( 1000 );
    Delay_ms ( 500 );
}

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.Thermo13

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.
