Temp-Log Click

Temp-Log 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 returns values of the temperature from the sensor.

Example Libraries

• MikroSDK.Board
• MikroSDK.Log
• Click.TempLog

Example Key Functions

• templog_cfg_setup Config Object Initialization function.

void templog_cfg_setup ( templog_cfg_t *cfg );

• templog_init Initialization function.

err_t templog_init ( templog_t *ctx, templog_cfg_t *cfg );

• templog_default_cfg Click Default Configuration function.

void templog_default_cfg ( templog_t *ctx );

• temp_log_read_temp_dec This function reads decimal value of temp.

uint16_t temp_log_read_temp_dec  ( templog_t *ctx, uint16_t resolution );

• temp_log_convert_to_celsius This function converts temperature data to celsius value.

float temp_log_convert_to_celsius  ( uint16_t temperature_data );

• temp_log_get_alert This function alerts user if temperature limit is alarming.

uint8_t temp_log_get_alert  ( templog_t *ctx );

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 );
}

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.
