kompilier mal den code hier:

#include "asuro.h"

#define SPEED  0x8F

int speedLeft,speedRight;
unsigned int lineData[2];
int ADOffset;

void LineLeft (void)
{
	speedLeft  += 1;
	if (speedLeft > 0xFE) speedLeft = 0xFF;
}

void LineRight (void)
{
	speedRight  += 1;
	if (speedRight > 0xFE) speedRight = 0xFF;
}

int main(void)
{
	int i;
	unsigned char j;

	Init();

	FrontLED(ON);
	while(1) (j = 0; j < 0xFF; j++) {
		LineData(lineData);}
		LineData(lineData);
		ADOffset = lineData[0] - lineData[1];
		speedLeft = speedRight = SPEED;
		(;;while(1) {
			LineData(lineData);
			i = (lineData[0] - lineData[1]) - ADOffset;
			if ( i > 4) {
				StatusLED(GREEN);
				LineLeft();
			}
			else if ( i < -4) {
				StatusLED(RED);
				LineRight();
			}
			else {
				StatusLED(OFF);
				speedLeft = speedRight = SPEED;
			}
			MotorSpeed(speedLeft,speedRight);
		}
		return 0;
}

mal so ne kleine frage zum linienverfolger......
wofür benutzt ihr folgenden code und was bedeutet er?
hier der code:
for (j = 0; j < 0xFF; j++) LineData(lineData);
was haben die hexadezizahlen zu bedeuten? thx im voraus!

statt 0xFF kann man auch einfach 255 schreiben.
manche leute machen sich das leben halt künstlich schwer

Danke für die Antwort

tja äh, manchmal zieht ein kleiner fehler einen gnazen rattenschnanz hinterher ich schu mal woran das liegt

[MarkusH91]

Ok Danke LOL
MfG MarkusH91

[EDH]

der code hier müsste eigentlcih funktioniern (zumindest gibts keine fehlermeldungen)

#include "asuro.h"

#define SPEED  0x8F

int speedLeft,speedRight;
unsigned int lineData[2];
int ADOffset;

void LineLeft (void)
{
   speedLeft  += 1;
   if (speedLeft > 0xFE) speedLeft = 0xFF;
}

void LineRight (void)
{
   speedRight  += 1;
   if (speedRight > 0xFE) speedRight = 0xFF;
}

int main(void)
{
int i;
unsigned char j;

   Init();

   FrontLED(ON);
   for (j = 0; j < 0xFF; j++) {
   LineData(lineData);}
   LineData(lineData);
   ADOffset = lineData[0] - lineData[1];
   speedLeft = speedRight = SPEED;
   while (1) {
      LineData(lineData);
      i = (lineData[0] - lineData[1]) - ADOffset;
      if ( i > 4) {
         StatusLED(GREEN);
         LineLeft();
      }
      else if ( i < -4) {
         StatusLED(RED);
         LineRight();
      }
      else {
         StatusLED(OFF);
         speedLeft = speedRight = SPEED;
      }
      MotorSpeed(speedLeft,speedRight);
   }
   return 0;
}

keine garantie

LineData(data) wird 255 (0FF) mal aufgerufen bzw. die FotoLEDs da vorne am Asuro ausgelesen.

[odysee_2002]

Hallo,

so wie ich das Programm verstehe, macht es keinen Sinn, 255 ( 0xFF = 255 dezimal) mal die Linedatas auszulesen. Für was, wenn es dann nicht verwendet wird?

Die Anmerkung, daß mit dem Offset eine Kalibrierung stattfindet, war schon richtig. Besser wäre es, für jeden Sensor einen eigenen Offset zu ermitteln.

Gruß
