Jaguar Non-FRC Firmware

Yes as I said there was NO change to the software I was using. The software worked for voltage and position control. PID was 10, 0.02, 0.02. Encoders were read and Jags reported position and speed.

This way you can get the various modes working and then troubleshoot your own method of connecting to the Jaguar. BDC-COMM offers an easy way to see what parameters need to be set to get the modes to run correctly.

Without more detail on what you're doing, I can't help troubleshoot the problem.



We only have the latest firmware versions on the web.

If I had a serial port I would. But cant until I have access to one.

Like I said the jaguar can protocol is being used just its being sent to the 2CAN as raw can frames. Here is a sample piece of code that should work.

CANJaguar canJaguar = new CANJaguar(2, CANJaguar.ControlMode.kSpeed);
        canJaguar.setSpeedReference( CANJaguar.SpeedReference.kEncoder);
        
        canJaguar.configEncoderCodesPerRev((short)20);
        canJaguar.setPID(10, 0.02, 0.02);

        canJaguar.enableControl(0);

        while(true)
        {
            canJaguar.set(100);
            
            try
            {
                Thread.sleep(10);
            }
            catch(InterruptedException excep)
            {}
        }
