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 :
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 );
}

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.
