Library Description

The library contains all the necessary functions for converting ADC values to real voltages and pressure values.

Key functions:

• float pressure12_getPressure(uint16_t adcValue) - Convert ADC value to Pressure data in mBar.
• float pressure12_getVoltage(uint16_t adcValue) - Convert ADC value to Voltage in mV.
• void pressure12_setMaxVoltage(float volt) - Sets max output voltage on the AN pin.

Examples description

The application is composed of three sections :

• System Initialization - Initializes LOG for logging data.
• Application Initialization - ADC init.
• Application Task - Reads ADC value, Convert ADC data to Voltage[mV] on the AN pin and convert to Pressure data in mBar. All data logs to the USBUART every 1sec.

	void applicationTask()
{
    uint16_t ADC_value;
    float Voltage;
    float Pressure;
    char demoText[ 50 ];

    ADC_value = pressure12_adcRead();
    Voltage = pressure12_getVoltage(ADC_Value);
    Pressure = pressure12_getPressure(ADC_Value);

    WordToStr(ADC_value, demoText);
    mikrobus_logWrite(" ADC value: ", _LOG_TEXT);
    mikrobus_logWrite(demoText, _LOG_LINE);

    FloatToStr(Voltage, demoText);
    mikrobus_logWrite(" Voltage: ", _LOG_TEXT);
    mikrobus_logWrite(demoText, _LOG_TEXT );
    mikrobus_logWrite(" mV", _LOG_LINE );

    FloatToStr(Pressure, demoText);
    mikrobus_logWrite(" Pressure: ", _LOG_TEXT);
    mikrobus_logWrite(demoText, _LOG_TEXT);
    mikrobus_logWrite(" mBar", _LOG_LINE );

    mikrobus_logWrite("--------------------------", _LOG_LINE);
    Delay_ms( 1000 );
}

Other mikroE Libraries used in the example:

• ADC Library
• Conversion 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.
