Does anyone know if the 2.0 Vex Cortex is able to control any type of servo with the setServo command in RobotC. I am getting a robot arm kit off the internet and want to replace the included servo controller with the cortex so I can use the Vex joystick.
The servos use PWM and I know the Vex uses it to control the official Vex Servos, so can anyone confirm it will work?
Yes, standard servos work just fine with VEX Cortex. You can use the setServo command, but you don’t have to do it that way. Setting the motor[port_of_interest] pseudo-array (intrinsic function) to a value between -127 and 127 will cause the servo to take the correct position. I believe, due to a signal timing choice by the Cortex designers, that the full range of servo motion is not quite achievable. But there is plenty of “control authority” available; I’ve not seen it be a problem.
Thank you so much!
If you want, I could give you the code that I used that allowed a normal motor to function like a servo.
