Temp-Log Click is a precise ambient temperature measurement device, equipped with 8Kbit (1024 bytes) of EEPROM memory, which can be used to permanently store system configuration or log application specific or user preference data. This Click covers a range of temperatures from -55°C to +125°C with the highest accuracy of ±0.5°C, in the range of 0°C to 85°C. The device can also send an ALERT signal to the INT pin of the mikroBUS™ every time programmed temperature thresholds are reached.

Click library

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

Software Support

We provide a library for the TempLog 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 TempLog Click driver.

Standard key functions :

  • Config Object Initialization function.

    void templog_cfg_setup ( templog_cfg_t *cfg );

  • Initialization function.

    TEMPLOG_RETVAL templog_init ( templog_t ctx, templog_cfg_t cfg );

  • Click Default Configuration function.

    void templog_default_cfg ( templog_t *ctx );

Example key functions :

  • This function reads decimal value of temp.

    uint16_t temp_log_read_temp_dec ( templog_t *ctx, uint16_t resolution);

  • This function converts temperature data to celsius value.

    float temp_log_convert_to_celsius ( uint16_t temperature_data);

  • This function alerts user if temperature limit is alarming.

    uint8_t temp_log_get_alert ( templog_t *ctx);

Examples Description

This example returns values of the temperature from the sensor.

The demo application is composed of two sections :

Application Init

Initializes Click driver.


void application_init ( void )
{
    log_cfg_t log_cfg;
    templog_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 " );

    // Click initialization.
    templog_cfg_setup ( &cfg );    
    TEMPLOG_MAP_MIKROBUS( cfg, MIKROBUS_1 );
    if ( TEMPLOG_OK != templog_init ( &templog, &cfg ) )
    {
        log_error( &logger, " Communication init." );
        for ( ; ; );
    }

    templog_default_cfg ( &templog );

    log_info( &logger, " Application Task " );
}

Application Task

Reads temperature from temperature register in decimal value in 9-bit resolution, converts that decimal value in celsius value and checks Alert pin witch goes active (low) if the measured temperature meets or exceeds the high temperature limit.


void application_task ( void )
{
    uint16_t temp_in_dec = 0;
    float temp_in_cels = 0;

    temp_in_dec = temp_log_read_temp_dec(&templog, TEMP_LOG_RESOLUTION_9_BITS);
    temp_in_cels = temp_log_convert_to_celsius(temperature);

    log_printf(&logger, "Temperature in decimal value is: %d\n", temp_in_dec);
    log_printf(&logger, "Temperature in celsius value is: %f\n", temp_in_cels);

    if(temp_log_get_alert(&templog) == 0)
    {
        log_printf( &logger, "TEMPERATURE LIMIT ALARMING!\r\n" );
    }

    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.TempLog

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.

BATT Boost 2 Click

0

BATT Boost 2 Click is a compact add-on board designed to extend the battery life of non-rechargeable, primary batteries in low-voltage, low-power applications. This board features the NBM7100A, a coin-cell battery-life booster with adaptive power optimization from Nexperia. The NBM7100A integrates two high-efficiency DC-DC conversion stages and an intelligent learning algorithm to optimize energy usage, allowing it to handle bursts of current up to 200mA without depleting the battery. It features two output terminals: VDH for high pulse load applications and VDP for powering 'Always-ON' components. Communication with the host MCU is achieved via the I2C interface, supporting up to 1MHz clock frequencies.
