Hey
ich habe folgendes Problem, nämlich das wenn ich das linienfolgeprogramm:
compilieren will kommt folgender error:Code://
// Program used by "myIrAsuro" in qualifying for competition
// "Parallel Slalom" of RobotChallenge 2007 in Vienna (24th march):
// http://www.robotchallenge.at
//
// Time 10.1s for 354cm, that is speed 35.05cm/s (best was 60.00 cm/s).
//
// myIrAsuro has reduction of 1:12.5 (Asuro standard is 1:25), see:
// https://www.roboternetz.de/phpBB2/ze...ag.php?t=28876
//
// The entries 0xFF for both SPEED values below will work on
// a standard Asuro with speed < 0.5m/s.
//
// The value for THRESHOLD must be changed if no IR-FrontLED
// with white shield is used, see:
// https://www.roboternetz.de/phpBB2/ze...ag.php?t=29109
//
//
// Robot will have to be placed on the line for starting!
//
// After starting the StatusLED of Asuro will blink [ready].
// After (any) switch is pressed both BackLED's turn on [steady].
// Releasing the switch will start the Robot [go].

was mach ich falsch.Zitat:

Ach jaich hab mir die lib 2.7 installiert(*.exe) kann es vieleicht daran liegen das ich deswegen noch was einstellen muss?
