Steve,
please try with this demo code (in NQC).
I think the "trick" is in the 100 ms output pulse length.
task main()
{
// configura sensore touch su porta 1
SetSensorType(SENSOR_1, SENSOR_TYPE_TOUCH);
SetSensorMode(SENSOR_1, SENSOR_MODE_BOOL);
// minimum needed power
SetPower(OUT_A, 4);
Dritto();
while (true) {
Curva();
Wait(100);
Dritto();
Wait(100);
}
}
void Dritto()
{
int retry = 3;
if (SENSOR_1 == 0)
do {
OnRev(OUT_A);
Wait(10);
Off(OUT_A);
retry--;
}
while ((SENSOR_1 == 0) && (retry >= 0));
}
void Curva()
{
int retry = 3;
if (SENSOR_1 == 1)
do {
OnFwd(OUT_A);
Wait(10);
Off(OUT_A);
retry--;
}
while ((SENSOR_1 == 1) && (retry >= 0));
}
