Temp-Log 2 Click

Temp-Log 2 Click demo application is developed using the NECTO Studio, ensuring compatibility with mikroSDK's open-source libraries and tools. Designed for plug-and-play implementation and testing, the demo is fully compatible with all development, starter, and mikromedia boards featuring a mikroBUS™ socket.

Example Description

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

Example Libraries

• MikroSDK.Board
• MikroSDK.Log
• Click.TempLog2

Example Key Functions

• templog2_cfg_setup Configuration Object Setup function.

void templog2_cfg_setup ( templog2_cfg_t *cfg );

• templog2_init Click Initialization function.

err_t templog2_init ( templog2_t *ctx, templog2_cfg_t *cfg );

• templog2_default_cfg Click Default Configuration function.

void templog2_default_cfg ( templog2_t *ctx );

• templog2_write_reg Write Register function.

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

• templog2_read_reg Read Register function.

err_t templog2_read_reg ( templog2_t *ctx, uint8_t reg_addr, uint16_t *data_out );

• templog2_read_temp Read Temperature function.

float templog2_read_temp ( templog2_t *ctx );

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_POSITION_TEMPLOG2 );
    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" );
        }
    }
}

Application Output

This Click board can be interfaced and monitored in two ways:

• Application Output - Use the "Application Output" window in Debug mode for real-time data monitoring. Set it up properly by following this tutorial.
• UART Terminal - Monitor data via the UART Terminal using a USB to UART converter. For detailed instructions, check out this tutorial.

Additional Notes and Information

The complete application code and a ready-to-use project are available through the NECTO Studio Package Manager for direct installation in the NECTO Studio. The application code can also be found on the MIKROE GitHub account.
