The only problem is that I'm not sure that I'm using it properly. I'm no expert in using the serial port on the roboRIO, and I have a feeling that something somewhere is going wrong. Does anybody know where this error might be coming from? our code is at https://github.com/Sparky384/Team384Year2015



Code:
Error on line 115 of SerialPort.cpp: HAL - VISA: Resource Locked

	at /home/lvuser/FRCUserProgram() [0x1194c]

Thanks for your time! If you have any questions about the code feel free to ask them. All the relevant gyro calls are in the drivetrain subsystem file.
Took a quick look at the code you've linked to. Looked around and couldn't find any code attempting to initialize the navX MXP. Looked in Subsystems\DriveTrain.cpp, but didn't see anything there except a Gyro instance.

Note that you need to use one of the classes in the navX MXP folder, not the Gyro class from the WPI Library (that only works w/the kit-of-parts gyro). See the example Robot.cpp file in the navX MXP folder for an example.

Perhaps the latest code is not checked in - or I'm looking in the wrong place. Can you please point me to the exact file and line number where the navX MXP initialization is occuring? Also, I didn't see a RobotMap.cpp file anywhere, though I did see RobotMap.h - maybe a sign not everything is checked in?
