pic18f43k22 adc error

[bhan1992]

i try to build the code below but it gives me the following errors. i checked that 'ADC_8ANA_0REF' is in the 'adc.h' header.

#include <p18f43k22.h>
#include <adc.h>
#include <delays.h>
#include <stdlib.h>
#include <timers.h>
#include <salvo.h>
#undef OSC

void main (void)
{
	TRISB = 0;

	OSCreateTask(slow_beep, OSTCBP(1), 7);
	OSCreateTask(medium_beep, OSTCBP(2), 7);
	OSCreateTask(fast_beep, OSTCBP(3), 7);

	OpenTimer0 (TIMER_INT_ON & T0_16BIT & T0_SOURCE_INT & T0_PS_1_1);
	WriteTimer0(55536);
	INTCONbits.GIE = 1;

	OpenADC (ADC_FOSC_32 & ADC_RIGHT_JUST & ADC_2_TAD & ADC_8ANA_0REF, ADC_CH0 & ADC_INT_OFF);
	PORTB = 1;		//initialisation 0.7 second beep
	Delay10KTCYx(10);	
	PORTB = 0;

	while(1)
	{
	SetChanADC(ADC_CH0);
	ConvertADC();
	while(BusyADC());
	result = ReadADC();
	OSSched();
	OS_Delay(10,main)	//delay0.1 second
	}
	CloseADC();
}

Error [1105] symbol 'ADC_8ANA_0REF' has not been defined
Error [1203] too few arguments in function call

Hi,

You'll probably need to look into adc.h for how OpenADC() is declared and the ADC_' macros are defined for the '4620. The number of parameters and proper combination of ADC_' masks are likely to be accounted for in the fact that the '4620 has three ADCON' registers, not two.

Best regards,
