Post Reading motor PID values
Is there a way to read the Proportional (in the PID controller) value on a standard NXT servo motor?
I'm trying to write a code that detects when a motor is undergoing a certain amount of stress. Is there a way to do that?
Likewise, is there a way to read the PID or "output" value for a motor?
I found that "motorPowerSigned[motorA]" will read the "assigned" power, I just need to know the actual "output" value. Then I can compare the assigned and actual powers to determine the amount of stress.

Thanks in advance.

I've been waiting for over three weeks, and still got no answer.
Can anyone please answer my questions?

Hi there,

I have no experience with this, but there's a property called "motorPWMLevel[motorIndex]" for the NXT, which returns the current PWM value pushed to the motor. I am not sure the PID values can be read from inside the ROBOTC program. I know the debugger can read this data, but they're internal values.
