in the simple program ther is a fail call --> compass sensor .
can you explain me how the heading is calculated ?????
ther is the parameter nCycles ......did he help for the heading calculate ???

the program is :

[color=blue][b]#include "Compass Sensor Driver.c"

task main()
{
int nCompassHeading;
long nCycles = 0;


const tSensors kCompass = S1;




SensorType[kCompass] = sensorI2CCustomStd;
SensorSubType[kCompass] = subTypeHiTechnicCompass;
StartTask(taskCompassDeviceDriver);



nxtDisplayTextLine(3, "Compass Port: %d", kCompass);

while (true)
{
++nCycles;
nCompassHeading = SensorValue[kCompass];
nxtDisplayTextLine(5, "Heading: %d", (short) nCompassHeading);
nxtDisplayTextLine(7, "Cycles: %d", nCycles);
}
return;
