摘要
近年来随着单片机技术的发展，性能的加强，其应用正不断走向深入。通过使用磁角度传感器对当前齿轮的角度进行测量，得出用户决定齿轮的正转或反转结论，正是本课题所研究的目的。
In recent years the MCU’s technology continues to develop,performance continues to strengthen, MCU’s applications are continually deepening.By using the magnetic angle sensor to measurement the angle of gear, According it , user decides to turn forward or reverse gear to achieve the purpose of controlling gear, This is just the aim of the research.
