Click library

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

Software Support

We provide a library for the Thermo8 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 Thermo8 Click driver.

Standard key functions :

  • Config Object Initialization function.

    void thermo8_cfg_setup ( thermo8_cfg_t *cfg );

  • Initialization function.

    THERMO8_RETVAL thermo8_init ( thermo8_t ctx, thermo8_cfg_t cfg );

  • Click Default Configuration function.

    void thermo8_default_cfg ( thermo8_t *ctx );

Example key functions :

  • This function returns the temperature value in �C.

    float thermo8_get_temperature ( thermo8_t *ctx );

  • This function sets the conversion resoult temperature step depending on the passed constant.

    void thermo8_set_resolution ( thermo8_t *ctx, uint8_t r_cfg );

  • This function setting the temperature alarm levels for the lower, upper and critical alert levels.

    void thermo8_limit_set ( thermo8_t *ctx, uint8_t limit_reg_addr, float limit );

Examples Description

This application measures temperature.

The demo application is composed of two sections :

Application Init

Initialize device.


void application_init ( void )
{
    log_cfg_t log_cfg;
    thermo8_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 ----\r\n" );

    //  Click initialization.

    thermo8_cfg_setup( &cfg );
    THERMO8_MAP_MIKROBUS( cfg, MIKROBUS_1 );
    thermo8_init( &thermo8, &cfg );
    Delay_ms ( 100 );
    thermo8_default_cfg( &thermo8 );
}

Application Task

Wait for the interrupt pin to be triggered. When the measured temperature breaches the upper or lower limit the temperature value as well as the status of the breach is is shown on the serial port (UART).


void application_task ( void )
{
    float t_data;
    char alert;
    char alert_on;

    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    alert = thermo8_ale_get( &thermo8 );

    if ( alert == 0 )
    {
        t_data  = thermo8_get_temperature( &thermo8 );
        alert_on = thermo8_get_alert_stat( &thermo8 );
    }

    if ( alert_on & THERMO8_TLOWER_REACHED )
    {
        log_printf( &logger, "Temperature under the low limit: %.2f �C \r\n", t_data );
    }

    if ( alert_on & THERMO8_TUPPER_REACHED )
    {
        log_printf( &logger, "Temperature over the high limit: %.2f �C \r\n", t_data );
    } 

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.Thermo8

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.

DAC 18 Click

0

DAC 18 Click is a compact add-on board for converting general-purpose input to PWM signals. This board features the DAC539G2-Q1, a 10-bit smart DAC from Texas Instruments. The board offers two key output channels: one for digital-to-analog conversion (OUT1) and the other for voltage-to-PWM conversion (OUT0) supporting triangle or sawtooth waveforms. It features an operational mode selection pin for I2C programming or standalone operation, along with nonvolatile memory for storing register settings. DAC 18 Click is ideal for automotive lighting systems and industrial environments requiring reliable signal conversion.
