Click library

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

Software Support

We provide a library for the Thermo4 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 Thermo4 Click driver.

Standard key functions :

  • Config Object Initialization function.

    void thermo4_cfg_setup ( thermo4_cfg_t *cfg );

  • Initialization function.

    THERMO4_RETVAL thermo4_init ( thermo4_t ctx, thermo4_cfg_t cfg );

  • Click Default Configuration function.

    void thermo4_default_cfg ( thermo4_t *ctx );

Example key functions :

  • This function reads temperature values in Celsius format.

    float thermo4_read_temperature_c ( thermo4_t *ctx );

  • This function reads temperature values in Farenheit format.

    float thermo4_read_temperature_f ( thermo4_t *ctx );

  • This function is used to reset the sensor.

    void thermo4_reset ( thermo4_t *ctx );

Examples Description

This demo example returns temperature values in three different format.

The demo application is composed of two sections :

Application Init

Initializes the driver and makes an initial log.


void application_init ( void )
{
    log_cfg_t log_cfg;
    thermo4_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 );

    //  Click initialization.

    thermo4_cfg_setup( &cfg );
    THERMO4_MAP_MIKROBUS( cfg, MIKROBUS_1 );
    thermo4_init( &thermo4, &cfg );
    log_info( &logger, "---- Application Init ----" );
}

Application Task

Returns temperature values from the sensor.


void application_task ( void )
{
    temp_in_celsius = thermo4_read_temperature_c( thermo4 );
    temp_in_faren = thermo4_read_temperature_f( thermo4 );
    temp_in_kelvin = thermo4_read_temperature_k( thermo );

    log_printf(" Temperature celsius : %f %c\r\n", temp_in_celsius, deg_cel);
    log_printf(" Temperature farenheit : %f %c\r\n", temp_in_faren, deg_far);
    log_printf(" Temperature kelvin : %f K\r\n", temp_in_kelvin);

    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.Thermo4

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.

PWR Meter 3 Click - 90A is a compact add-on board that measures voltage and current through the connected load. This board features the ACS37800KMACLU-090B3-I2C, an I2C-configurable power monitoring solution from Allegro MicroSystems, which simplifies the addition of power monitoring to many AC/DC powered systems. The ACS37800KMACLU-090B3-I2C Hall-effect-based current sensing technology achieves reinforced isolation ratings (4800 VRMS) alongside a reliable ±90A bidirectional current sensing. It also has two LED indicators for the realization of visual detection of some anomalies in operation, such as under/overvoltage and fast overcurrent fault detection.
