Temp ISO Click

Temp ISO 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.

• Type : ADC type

Software Support

Example Description

This example demonstrates the use of Temp ISO Click board by reading and displaying the temperature measurements.

Example Libraries

• MikroSDK.Board
• MikroSDK.Log
• Click.TempISO

Example Key Functions

• tempiso_cfg_setup Config Object Initialization function.

void tempiso_cfg_setup ( tempiso_cfg_t *cfg );

• tempiso_init Initialization function.

err_t tempiso_init ( tempiso_t *ctx, tempiso_cfg_t *cfg );

• tempiso_read_temperature This function reads the voltage level from AN pin and converts it to temperature in degrees Celsius.

err_t tempiso_read_temperature ( tempiso_t *ctx, float *data_out );

• tempiso_read_voltage_avg This function reads a desired number of ADC samples and calculates the average voltage level.

err_t tempiso_read_voltage_avg ( tempiso_t *ctx, uint16_t num_conv, float *voltage_avg );

• tempiso_set_vref This function sets the voltage reference for Temp ISO Click driver.

err_t tempiso_set_vref ( tempiso_t *ctx, float vref );

Application Init

Initializes the driver and logger.

void application_init ( void )
{
    log_cfg_t log_cfg;  /**< Logger config object. */
    tempiso_cfg_t tempiso_cfg;  /**< Click config object. */

    /** 
     * 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.
    tempiso_cfg_setup( &tempiso_cfg );
    TEMPISO_MAP_MIKROBUS( tempiso_cfg, MIKROBUS_1 );
    if ( ADC_ERROR == tempiso_init( &tempiso, &tempiso_cfg ) )
    {
        log_error( &logger, " Communication init." );
        for ( ; ; );
    }
    
    log_info( &logger, " Application Task " );
}

Application Task

Reads the temperature measurement in degrees Celsius and displays the results on the USB UART approximately once per second.

void application_task ( void )
{
    float temperature = 0;
    if ( TEMPISO_OK == tempiso_read_temperature ( &tempiso, &temperature ) ) 
    {
        log_printf( &logger, " Temperature: %.1f degC\r\n\n", temperature );
        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.
