Re: 2012: Tuning the Jaguar's Speed Control PID Loop

Have you done any of this with C++ or can you offer some suggestions on the best way to set PID constants on the DS , send them to the robot and retrieve the sensor data and display it.
The original CAN Jaguar examples from 2010 showed a decent way to do this. They don't use the modern APIs, but the concepts are all still applicable. You can still download them from firstforge.wpi.edu in the CANJaguar project.
