重力传感器也称为加速度传感器，源代码编译环境需要SDK 1.5(api 3)支持。 　　此传感器不仅对玩家反转手机的动作可以检测到，而且会根据反转手机的程度,得到传感器的值也会不同！ -Gravity sensor, also known as acceleration sensors, the source code is compiled environment requires SDK 1.5 (api 3) support. This sensor is not only the a

level control demo code, use dsPIC33F and MPLAB, test sensor level
