Library Description

The library contains basic functions for working with the Force 3 click.

Key functions:

• uint16_t force3_read_raw_data( ) - Read 12bit raw data

Examples description

The application is composed of three sections :

• System Initialization - Initializes I2C module
• Application Initialization - Initializes driver init
• Application Task - Reads sensor raw data and shows the pressure on the sensor.

void application_task ( )
{
    uint16_t raw_data;
    char demo_text[ 20 ];

    raw_data = force3_read_raw_data();
    IntToStr( raw_data, demo_text );
    mikrobus_logWrite( "Raw data: ", _LOG_TEXT );
    mikrobus_logWrite( demo_text, _LOG_LINE );

    if ( ( raw_data > 15 ) && ( raw_data <= 200 ) )
    {
       mikrobus_logWrite( ">> Light touch", _LOG_LINE );
    }
    else if ( ( raw_data > 200 ) && ( raw_data <= 500 ) )
    {
       mikrobus_logWrite( ">> Light squeeze", _LOG_LINE );
    }
    else if ( ( raw_data > 500 ) && ( raw_data <= 800 ) )
    {
       mikrobus_logWrite( ">> Medium squeeze", _LOG_LINE );
    }
    else if ( raw_data > 800 )
    {
       mikrobus_logWrite( ">> Big squeeze", _LOG_LINE );
    }
    
    mikrobus_logWrite( "----------------------", _LOG_LINE );
    Delay_ms( 1500 );
}

• I2C Library - Conversions Library

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.
