Hello,
I'm trying to use the files and functions generated by maestro to display voltage on LCD using the variable POT it comes with. I can display text fine, but I can't seem to be able to display the voltage on the screen as I turn the Pot. below is the code, any help will be appreciated.

Code:

#include "xlcd.h"
// Fosc = 22.1184MHz

#pragma config BOREN = OFF
#pragma config PBADEN = OFF
rom const char volttxtstrng[]="PRES ::";

int result;
ADCON1 = 0b00001110;
XLCDInit();
XLCDClear();
XLCDPutRomString(volttxtstrng);

XLCDPutRomString(temptxtstrng);
while (1)
{
OpenADC(ADC_FOSC_16 & ADC_RIGHT_JUST & ADC_4_TAD, ADC_CH0 & ADC_INT_OFF, ADC_1ANA);
ConvertADC(); // Start conversion
while( BusyADC() ); // Wait for completion
result = ReadADC(); // Read result
result = ((result/(1023))*5*1000);
XLCDPut(result);
CloseADC(); // Disable A/D converter
}
}
