Question

Assuming fosc=4MHz, derive the following information from the program below:

#include <p18F452.h>

#include <stdlib.h>

#include <ADC.h>

#include <stio.h>

#include <delays.h>

Int X=0

void main (void) { While (1)

{
OpenADC (ADC_FOSC_32 & ADC_RIGHT_JUST & ADC_1ANA_0REF,

ADC_CH1 & ADC_INT_OFF); Delay1KTCYx(10);
Convert ADC( );
While (BusyADC( ));

X = ReadADC( );

Delay10KTCYx(200); }

}

a) The channel used

b) The number of sensors

c) The period of the A/D converter

d) The acquisition time

e) How often the measurements are done?

Explanation / Answer

c) The period of the A/D converter

#include <p18F452.h>

#include <stdlib.h>

#include <ADC.h>

#include <stio.h>

#include <delays.h>

Int X=0

void main (void) { While (1)

{
OpenADC (ADC_FOSC_32 & ADC_RIGHT_JUST & ADC_1ANA_0REF,

ADC_CH1 & ADC_INT_OFF); Delay1KTCYx(10);
Convert ADC( );
While (BusyADC( ));

X = ReadADC( );

Delay10KTCYx(200); }

}
