 Encoder help This is our failed encoder attempt. we can't figure out whats wrong, if anyone could either tell us what what we did wrong or post a working code.
#pragma config(Hubs, S1, HTMotor, HTServo, none, none)
#pragma config(Motor, motorA, motorA, tmotorNormal, PIDControl, encoder)
#pragma config(Motor, mtr_S1_C1_1, motorD, tmotorNormal, PIDControl, reversed, encoder)
#pragma config(Motor, mtr_S1_C1_2, motorE, tmotorNormal, PIDControl, encoder)
#pragma config(Servo, srvo_S1_C2_1, , tServoNormal)
#pragma config(Servo, srvo_S1_C2_2, , tServoNormal)
//*!!Code automatically generated by 'ROBOTC' configuration wizard !!*//
task main()
{
nMotorEncoder[motorE] = 0;
nMotorEncoder[motorD] = 0;
nMotorEncoderTarget[motorE] = 100;
nMotorEncoderTarget[motorD] = 100;
motor[motorE] = 100;
motor[motorD] = 100;
while(nMotorEncoder[motorE] > 100);
{
motor[motorE] = 0;
motor[motorD] = 0;
}
}

Re: Encoder help Your while condition at the end will not execute because it is false from the beginning (the encode could not have reached 100 yet). I assume you wanted to wait until the encode reached 100 and then set the motors to zero and exit? If so, you could change this: to something like this:

Re: Encoder help That did work, but now we are having another problem... it will not turn, can you help us with this one?  | | | | Code:
#pragma config(Hubs, S1, HTMotor, HTServo, none, none)
#pragma config(Motor, motorA, motorA, tmotorNormal, PIDControl, encoder)
#pragma config(Motor, mtr_S1_C1_1, motorD, tmotorNormal, PIDControl, reversed, encoder)
#pragma config(Motor, mtr_S1_C1_2, motorE, tmotorNormal, PIDControl, encoder)
#pragma config(Servo, srvo_S1_C2_1, , tServoNormal)
#pragma config(Servo, srvo_S1_C2_2, , tServoNormal)
//*!!Code automatically generated by 'ROBOTC' configuration wizard !!*//
task main()
{
nMotorEncoder[motorE] = 0;
nMotorEncoder[motorD] = 0;
wait1Msec(1);
motor[motorE] = 100;
motor[motorD] = 100;
while(nMotorEncoder[motorE] < 3000);
{
wait1Msec(1);
}
motor[motorE] = 0;
motor[motorD] = 0;
wait1Msec(1);
nMotorEncoder[motorE] = 0;

wait1Msec(1);

motor[motorD] = -100;
while(nMotorEncoder[motorE] < 5000);
{
wait1Msec(1);
}
motor[motorE] = 0;
motor[motorD] = 0;
wait1Msec(3000);

Re: Encoder help You code looks like it should work. Did you resolve the problem? If not, how did it fail, e.g. by going straight?
