HI to all.

i am new to robotc and new to c programming.
i try to write a program that move my robot just with ch1+ch2 on the remote.
the only part of the program that work is (ch2-up + ch1 left)
anyone know what am i doing rong?

here is my code :

/* conguration:

left motor= port2
right motor= port3
*/

task main ()
{
bMotorReflected[port2] = 1; // change motor 2 diraction because motore 2 is reverse side
bVexAutonomousMode = false; //Activates Remote Control Mode

while (1==1)
{
if (vexRT[Ch1] == 0 && vexRT[Ch2]>0) // if just channel 2 is active up > move forward
{
motor[port2]= vexRT[Ch2];
motor[port3]= vexRT[Ch2];
}
if (vexRT[Ch1] == 0 && vexRT[Ch2]<0 ) // if just channel 2 is active down > move backward
{
motor[port2]= vexRT[Ch2];
motor[port3]= vexRT[Ch2];
}
if (vexRT[Ch2]==0 && vexRT[Ch1] > 0 ) //if just channel 1 is active to right > move right in place
{
motor[port2]= vexRT[Ch1];
motor[port3]= - vexRT[Ch2];
}
if (vexRT[Ch2]==0 && vexRT[Ch1] < 0 ) // if just channel 1 is active to left > move left in place
{
motor[port2]= vexRT[Ch1];
motor[port3]= - vexRT[Ch2];
}
if (vexRT[Ch2]>0 && vexRT[Ch1] > 0 ) //if chanel 2 up and channel 1 right
{
motor[port2]= (vexRT[Ch2])-((vexRT[Ch2]* vexRT[Ch1])/127);
motor[port3]= vexRT[Ch2];
{
if (vexRT[Ch2]>0 && vexRT[Ch1] < 0 ) //if channel 2 up and channel 1 left
{
motor[port2]= vexRT[Ch2];
motor[port3]= (vexRT[Ch2])+((vexRT[Ch2]* vexRT[Ch1])/127);
}
if (vexRT[Ch2]<0 && vexRT[Ch1] > 0) //if channel 2 down and channel 1 right
{
motor[port2]= vexRT[Ch2];
motor[port3]= (vexRT[Ch2])-((vexRT[Ch2]* vexRT[Ch1])/127);
}
if (vexRT[Ch2]<0 && vexRT[Ch1] < 0) //if channel 2 down and channel 1 left
{
motor[port2]= (vexRT[Ch2])+((vexRT[Ch2]* vexRT[Ch1])/127);
motor[port3]= vexRT[Ch2];
}
else
{
motor[port2]= 0;
motor[port3]= 0;
}
}
}
}



Thanks for the help

Moved to correct forum.

Try this code out, a slightly modified version from the "Single Joystick Control" Sample program:

And if you remove the "/2" you won't limit your top speed artificially. That is the code I
