Problem 1 mit Snake-Vision
Hi
Ich habe die snake erweiterung jetzt zu sammen gebastelt nur habe ich ein kleines problem mit der Programmierung habe schon paar mal drüber geschaut aber der sagt mir immer etwas vom Token wo keiner ist und laut buch keiner hin soll
Hier mal der Code
Code:
#include "asuro.h"
#define THRESH1 20
#define THRESH2 80
#define THRESH3 200
void ThermalData (unsigned int *data) {
ADMUX = (1 << REFS0) | (1 << REFS1) | IR_LEFT;
ADCSRA |= (1 << ADSC);
while (!(ADCSRA & (1 << ADIF)));
ADCSRA |= (1 << ADIF);
data[0] = ADCL + (ADCH) << 8);
ADMUX = (1 << REFS0) | (1 << REFS1) | IR_RIGHT;
ADCSRA |= (1 << ADSC);
while (!(ADCSRA & (1 << ADIF)));
ADCSRA |= (1 << ADIF);
data[1] = ADCL + (ADCH) << 8);
}
int main(void)
{
unsigned int tdata[2];
unsigned int speed;
signed int diff,sum;
Init();
MotorDir(FWD,FWD);
while(1);
{
ThermalData(tdata);
sum=tdata[0]+tdata[1];
if (sum>THRESH1) {
StatusLED(GREEN);
speed=140;
}
if (sum>THRESH2) {
StatusLED(YELLOW);
speed=200;
}
if (sum>THRESH3) {
StatusLED(RED);
speed=255;
}
diff=((signed)tdata[0]-(signed)tdata[1])*32/sum;
if (diff>4) {
BackLED(ON,OFF);
MotorSpeed(0,speed);
}
else if (diff<-4) {
BackLED(OFF,ON);
MotorSpeed(speed,0);
}
else {
BackLED(OFF,OFF);
MotorSpeed(speed,speed);
}
}
else {
StatusLED(OFF);
BackLED(OFF,OFF);
MotorSpeed(0,0);
}
}
return 0;
}
Und Hier die Fehlermeldung

Bitte um Hilfe
Edit: OK habe es gefunden habe es so geschrieben data[0] = ADCL + (ADCH) << 8);
muss haber data[0] = ADCL + (ADCH << 8); so sein habe hinter der 8 ein ) das nicht dahin gehört
