Vacuum Click

Vacuum 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.

• Date : dec 2019.
• Type : I2C type

Software Support

Example Description

This application measuring absolute pressure.

Example Libraries

• MikroSDK.Board
• MikroSDK.Log
• Click.Vacuum

Example Key Functions

• vacuum_cfg_setup Config Object Initialization function.

void vacuum_cfg_setup ( vacuum_cfg_t *cfg );

• vacuum_init Initialization function.

err_t vacuum_init ( vacuum_t *ctx, vacuum_cfg_t *cfg );

• vacuum_generic_write Generic write function.

void vacuum_generic_write ( vacuum_t *ctx, uint8_t reg, uint8_t *data_buf, uint8_t len );

• vacuum_get_voltage Voltage reading function.

float vacuum_get_voltage ( vacuum_t *ctx );

• vacuum_get_percentage_of_vacuum Function for converting ADC value to percentage of Vacuum.

float vacuum_get_percentage_of_vacuum ( vacuum_t *ctx );

Application Init

Initialization driver init and calibration of the chip to start measuring.

void application_init ( void )
{
    log_cfg_t log_cfg;
    vacuum_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.

    vacuum_cfg_setup( &cfg );
    VACCUM_MAP_MIKROBUS( cfg, MIKROBUS_1 );
    vacuum_init( &vacuum, &cfg );

    vacuum_calibration( &vacuum );
}

Application Task

Reads vacuum percentage that sensor reads.

void application_task ( void )
{
    //  Task implementation.
    vacuum_volt = vacuum_get_voltage(  &vacuum );
    log_printf ( &logger, "Vacuum (voltage) : %.2f V\r\n ", vacuum_volt );
     
    vacuum_data = vacuum_get_percentage_of_vacuum(  &vacuum );
    log_printf ( &logger, "Percentage of vacuum: %.2f : \r\n ", vacuum_data );
    
    Delay_ms ( 300 );
}

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.
