Click library

  • Author : Nemanja Medakovic
  • Date : Nov 2019.
  • Type : I2C type

Software Support

We provide a library for the TempLog2 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 TempLog2 Click driver.

Standard key functions :

  • Configuration Object Setup function.

    void templog2_cfg_setup( templog2_cfg_t *cfg );

  • Click Initialization function.

    TEMPLOG2_RETVAL templog2_init( templog2_t ctx, templog2_cfg_t cfg );

  • Click Default Configuration function.

    void templog2_default_cfg( templog2_t *ctx );

Example key functions :

  • Write Register function.

    TEMPLOG2_RETVAL templog2_write_reg( templog2_t *ctx, uint8_t reg_addr, uint16_t transfer_data );

  • Read Register function.

    TEMPLOG2_RETVAL templog2_read_reg( templog2_t ctx, uint8_t reg_addr, uint16_t data_out );

  • Read Temperature function.

    float templog2_read_temp( templog2_t *ctx );

Examples Description

This example demonstrates the use of the Temp-Log 2 Click board.

The demo application is composed of two sections :

Application Init

Initializes peripherals and pins. Initializes I2C driver and performs device configuration. Sets total active conversion time to 250 ms and 8 average samples. Also sets Shutdown Mode as default mode, and after device reset puts device in Continuous Conversion Mode. High limit status will be set when temperature cross over the determined high limit temperature value. Low limit status will be set when temperature falls below the determined low limit temperature value.


void application_init( void )
{
    templog2_cfg_t templog2_cfg;
    log_cfg_t log_cfg;

    //  Click initialization.
    templog2_cfg_setup( &templog2_cfg );
    TEMPLOG2_MAP_MIKROBUS( templog2_cfg, MIKROBUS_1 );
    templog2_init( &templog2, &templog2_cfg );

    //  Click default configuration.
    templog2_default_config( &templog2 );

    /** 
     * 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, "----  Temp-Log 2 Application Init Done  ----\r\n" );
}

Application Task

Reads temperature value calculated to Celsius degrees.


void application_task( void )
{
    float temperature;
    uint8_t temp_status;
    uint8_t cnt;

    temp_status = templog2_data_ready( &templog2 );

    if (temp_status & _TEMPLOG2_DATA_READY_MASK)
    {
        temperature = templog2_read_temp( &templog2 );

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

        if (temp_status & _TEMPLOG2_LOW_LIMIT_MASK)
        {
            log_printf( &logger, " LOW LIMIT DETECTED!\r\n" );
        }

        if (temp_status & _TEMPLOG2_HIGH_LIMIT_MASK)
        {
            log_printf( &logger, " HIGH LIMIT DETECTED!\r\n" );
        }
    }
}

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.TempLog2

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.

IR Grid Click is a thermal imaging sensor. It has an array of 64 very sensitive factory calibrated IR elements (pixels), arranged in 4 rows of 16 pixels, each measuring an object temperature up to 300˚C within its local Field of View (FOV). The MLX90621ESF-BAD IR sensor used on this Click board™ has only four pins, and it is mounted inside of the industry standard TO39 package. It is equipped with 2Kbit of EEPROM for storing the compensation and calibration parameters.
