Software Support

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

Library Description

Library contains function for reading raw ADC data and function for reading data in [kPa]

Key functions :

• uint16_t diffpress_getAdcData( void ) - reads raw ADC data from device
• float diffpress_getPressureDifference( void ) - calculates pressure difference from raw ADC data
• -

Examples Description

The application is composed of three sections :

• System Initialization - Initializes LOG and I2C
• Application Initialization - Initializes I2C driver
• Application Task - Logs pressure difference

void applicationTask( )
{
    pressureDifference = diffpress_getPressureDifference( );

    FloatToStr( pressureDifference, text );
    
    mikrobus_logWrite( "pressure difference : ", _LOG_TEXT );
    mikrobus_logWrite( text, _LOG_TEXT );
    mikrobus_logWrite( " kPa", _LOG_LINE );

    Delay_ms(100);
}

The full application code, and ready to use projects can be found on our LibStock page.

Other mikroE Libraries used in the example:

• I2C
• UART
• Conversions

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.
