Automatically Read A Single Analog Input

	CloseADC10();// ensure the ADC is off before setting the configuration
	OpenADC10(
			(ADC_MODULE_ON | ADC_IDLE_STOP | ADC_FORMAT_INTG16 | ADC_CLK_AUTO | ADC_AUTO_SAMPLING_ON | ADC_SAMP_ON), //AD1CON1 register
			(ADC_VREF_AVDD_AVSS | ADC_SCAN_OFF | ADC_ALT_INPUT_OFF | ADC_SAMPLES_PER_INT_10),						//AD1CON2 register
			(ADC_SAMPLE_TIME_4 | ADC_CONV_CLK_PB | ADC_CONV_CLK_3Tcy),												//AD1CON3 register (SET THE SAMPLE TIME ETC)
			(ENABLE_AN0_ANA),																						//AD1PCFG register (SET THE ANALOG PINS)
			(0)																										//AD1CSSL register (SELECTS INPUTS TO BE SEQUENTIALLY SCANNED) (0 when ADC_SCAN_OFF)
			);
	EnableADC10();
	//Read the voltage from ADC1BUF0

If this doesn't work (seems to sometimes not) then simply use the Multiple Analog Inputs example below with just the one input defined in the last 2 arguments

	EnableADC10();
	//Read the voltage from the corresponding ADC1BUF0, ADC1BUF1 etc (Starts filling from ADC1BUF0 regardless of actual AN# pin numbers being sampled)

Converting Result To Voltage

	//10 bit AtoD (0 - 1023)
	//[Vsource] - 2K7 - [PIC] - 2K2 - [0V] Potential divider
	//1024 = 3.3V = 7.35Vsource
	//Result = (MaxReadingSource / MaxReading) * AtoD value
	UINT16 atod_vin_x100 = (UINT16)(((double)735 / 1024) * ADC1BUF0);
