AVR XMEGA ADC Compilefehler

nabend,

kann mir jemand sagen warum ich hier:

1

#include <avr/io.h>

2

#include "adc.h"

3

4

5

6

void init_adc(void)

7

{

8

9

 ADCB.CTRLA = ADC_ENABLE_bm; // Enable ADCB

10

 ADCB.CTRLB = ADC_RESOLUTION_8BIT_gc; // 8Bit Resolution

11

 ADCB.REFCTRL = ADC_REFSEL_AREFB_gc; // External Referance on AREFB 

12

 ADCB.PRESCALER = ADC_PRESCALER_DIV512_gc; // Prescaler = 512

13

 ADCB.CH0.CTRL = ADC_CH_INPUTMODE_SINGLEENDED_gc;   // Singleended

14

15

}

16

17

18

19

unsigned int read_adc_channel(unsigned char channel)

20

{

21

22

 ADCB.CH0.MUXCTRL = channel << 3;

23

24

 ADCB.CH0.CTRL |= ADC_CH_START_bm; 

25

 //while(!ADCB.CH0.INTFLAGS);

26

 while(((ADCB.CH0.INTFLAGS & ADC_CH_CHIF_bm) == 0x00));

27

28

 return ADCB.CH0RESH;

29

30

}

diese Fehler bekomme:
