Since there is no event in nxc. Is there anyway to interrupt this call via a Off(OUT_AC) in another task? RotateMotor(OUT_AC, 20, 800); I could have used a time Wait after onFwd.

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)
