Click library

  • Author : MikroE Team
  • Date : dec 2019.
  • Type : I2C type

Software Support

We provide a library for the Vacuum Click as well as a demo application (example), developed using MikroElektronika compilers. The demo can run on all the main MikroElektronika development boards.

Package can be downloaded/installed directly form compilers IDE(recommended way), or downloaded from our LibStock, or found on mikroE github account.

Library Description

This library contains API for Vacuum Click driver.

Standard key functions :

  • Config Object Initialization function.

    void vacuum_cfg_setup ( vacuum_cfg_t *cfg );

  • Initialization function.

    VACCUM_RETVAL vacuum_init ( vacuum_t ctx, vacuum_cfg_t cfg );

Example key functions :

  • Generic write function.

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

  • Voltage reading function.

    float vacuum_get_voltage ( vacuum_t *ctx );

  • Function for converting ADC value to percentage of Vacuum.

    float vacuum_get_percentage_of_vacuum ( vacuum_t *ctx );

Examples Description

This application measuring absolute pressure.

The demo application is composed of two sections :

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 );
}

The full application code, and ready to use projects can be installed directly form compilers IDE(recommneded) or found on LibStock page or mikroE GitHub accaunt.

Other mikroE Libraries used in the example:

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

Additional notes and informations

Depending on the development board you are using, you may need USB UART Click, USB UART 2 Click or RS232 Click to connect to your PC, for development systems with no UART to USB interface available on the board. The terminal available in all Mikroelektronika compilers, or any other terminal application of your choice, can be used to read the message.
