Air Velocity 2 Click

Air Velocity 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 Air Velocity 2 Click board by reading and displaying the output counts and air velocity in m/sec.

Example Libraries

• MikroSDK.Board
• MikroSDK.Log
• Click.AirVelocity2

Example Key Functions

• airvelocity2_cfg_setup This function initializes Click configuration structure to initial values.

  void airvelocity2_cfg_setup ( airvelocity2_cfg_t *cfg );

• airvelocity2_init This function initializes all necessary pins and peripherals used for this Click board.

  err_t airvelocity2_init ( airvelocity2_t *ctx, airvelocity2_cfg_t *cfg );

• airvelocity2_read_output This function reads the raw output counts by using I2C serial interface.

  err_t airvelocity2_read_output ( airvelocity2_t *ctx, uint16_t *out_counts );

• airvelocity2_counts_to_mps This function converts raw output counts to velocity in m/sec (0-15).

  float airvelocity2_counts_to_mps ( uint16_t out_counts );

Application Init

Initializes the driver and logger.

void application_init ( void )
{
    log_cfg_t log_cfg;  
    airvelocity2_cfg_t airvelocity2_cfg;  

    LOG_MAP_USB_UART( log_cfg );
    log_init( &logger, &log_cfg );
    log_info( &logger, " Application Init " );
 
    // Click initialization.
    airvelocity2_cfg_setup( &airvelocity2_cfg );
    AIRVELOCITY2_MAP_MIKROBUS( airvelocity2_cfg, MIKROBUS_POSITION_AIRVELOCITY2 );
    if ( I2C_MASTER_ERROR == airvelocity2_init( &airvelocity2, &airvelocity2_cfg ) ) 
    {
        log_error( &logger, " Communication init." );
        for ( ; ; );
    }
    
    log_info( &logger, " Application Task " );
}

Application Task

Reads the output counts and converts it to air velocity in m/sec. Both values will be displayed on the USB UART approximately every 125ms.

void application_task ( void )
{
    uint16_t out_counts = 0;
    if ( AIRVELOCITY2_OK == airvelocity2_read_output ( &airvelocity2, &out_counts ) )
    {
        log_printf ( &logger, " Out counts: %u\r\n", out_counts );
        log_printf ( &logger, " Air velocity: %.2f m/s\r\n\n", airvelocity2_counts_to_mps ( out_counts ) );
        Delay_ms ( 125 );
    }
}

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.
