However, This will not allow me to get a more previous degree turning. (...) (17 years ago, 3-Aug-07, to lugnet.robotics.nxt)

There are three steps to reading an I2C message from a sensor. 1. Send a message to the I2C sensor to initiate the read. Look at the program "NXT HiTechnic Accelerometer" in the RobotC sample programs folder for an example that you can clone. (...) (17 years ago, 1-Aug-07, to lugnet.robotics.nxt)
