Ozone 3 Click

Ozone 3 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.

Click Library

• Author : Nenad Filipovic
• Date : Apr 2021.
• Type : I2C type

Software Support

Example Description

This library contains API for the Ozone 3 Click driver. This demo application shows an example of the O3 ppm data measurement.

Example Libraries

• MikroSDK.Board
• MikroSDK.Log
• Click.Ozone3

Example Key Functions

• ozone3_cfg_setup Config Object Initialization function.

void ozone3_cfg_setup ( ozone3_cfg_t *cfg );

• ozone3_init Initialization function.

err_t ozone3_init ( ozone3_t *ctx, ozone3_cfg_t *cfg );

• ozone3_default_cfg Click Default Configuration function.

void ozone3_default_cfg ( ozone3_t *ctx );

• ozone3_read_adc Ozone 3 read ADC function.

uint16_t ozone3_read_adc ( ozone3_t *ctx );

• ozone3_get_o3_ppm Ozone 3 get O3 ppm function.

float ozone3_get_o3_ppm ( ozone3_t *ctx );

Application Init

Initialization of I2C module and log UART. After driver initialization the app set default settings.

void application_init ( void ) 
{
    log_cfg_t log_cfg;        /**< Logger config object. */
    ozone3_cfg_t ozone3_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.

    ozone3_cfg_setup( &ozone3_cfg );
    OZONE3_MAP_MIKROBUS( ozone3_cfg, MIKROBUS_1 );
    err_t init_flag = ozone3_init( &ozone3, &ozone3_cfg );
    if ( init_flag == I2C_MASTER_ERROR ) {
        log_error( &logger, " Application Init Error. " );
        log_info( &logger, " Please, run program again... " );

        for ( ; ; );
    }

    ozone3_default_cfg ( &ozone3 );
    log_info( &logger, " Application Task " );
    Delay_ms ( 300 );
}

Application Task

This is an example that shows the use of a Ozone 3 Click board™. Get and logs O3 ( Trioxygen ) data as ppm value. Results are being sent to the Usart Terminal where you can track their changes.

void application_task ( void ) 
{
    float o3_ppm = ozone3_get_o3_ppm( &ozone3 );
    log_printf( &logger, "\tOzone : %.2f ppm \r\n", o3_ppm );
    Delay_ms ( 500 );
}

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.
