Thermo K click

THERMO K click carries the MCP9600 IC from Microchip. Depending on the type of probe it uses the click can measure temperatures from −200 °C to +1372 °C.

Click library

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

Software Support

We provide a library for the ThermoK 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 ThermoK Click driver.

Standard key functions :

• Config Object Initialization function.

  ‍void thermok_cfg_setup ( thermok_cfg_t *cfg );

  - Initialization function.

  ‍THERMOK_RETVAL thermok_init ( thermok_t *ctx, thermok_cfg_t *cfg );

Example key functions :

• Temperature data

  ‍float thermok_get_temperature ( thermok_t *ctx, uint8_t reg, uint8_t temp_format );

  - Get status

  ‍void thermok_get_status ( thermok_t *ctx, thermok_alert_t *status );

• Functions for read device info

  ‍uint16_t thermok_get_device_info ( thermok_t *ctx );

  Examples Description

‍Demo application shows basic temperature reading using Thermo K click.

The demo application is composed of two sections :

Application Init

‍Configuring clicks and log objects. Reads the device ID and also checks the click and MCU communication.

void application_init ( void )
{
    log_cfg_t log_cfg;
    thermok_cfg_t cfg;
 
    LOG_MAP_USB_UART( log_cfg );
    log_init( &logger, &log_cfg );
    log_info( &logger, "---- Application Init ----" );
 
    //  Click initialization.
 
    thermok_cfg_setup( &cfg );
    THERMOK_MAP_MIKROBUS( cfg, MIKROBUS_1 );
    thermok_init( &thermok, &cfg );
 
    // Check communication and reads device ID
 
    device_info = thermok_get_device_info( &thermok );
 
    if ( ( device_info >> 8 ) == THERMOK_DEVICE_ID )
    {
        log_info(&logger, "---- Communication OK!!! ----" );
    }
    else
    {
        log_info(&logger, "---- Communication ERROR!!! ----" );
        for ( ; ; );
    }
    Delay_1sec( );
}

Application Task

‍Reads Temperature data(Type K probe) and this data logs to USBUART every 500ms.

void application_task ( void )
{
    float temperature;
 
    //  Task implementation.
 
    temperature = thermok_get_temperature( &thermok, 
                                           THERMOK_REG_HOT_JUNCTION_TEMP_THR, 
                                           THERMOK_TEMP_IN_CELSIUS );
    log_printf( &logger, ">> Temperature is %.2f C\r\n", temperature );
 
    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.ThermoK

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.
