IRQ4中断有三个中断源：1KHz、2Kz和4KHz,每一个中断分别控制与IOA0-IOA1,IOA2-IOA3和IOA4-IOA7相连的LED灯(IRQ4 interrupt has three interrupt sources: 1KHz, 2Kz and 4KHz, each interruption of the respective control and IOA0-IOA1, IOA2-IOA3 and IOA4-IOA7 connected LED lights)

说明：  无刷电机驱动器源代码。基于无传感器方案的无刷电机启动器。核心是换向角度检测：即电机反电势波形数据处理，经过衰减滤波，取出过零相位。应为低速反电势波形dB过小，波形扰动太大，本程序还不能稳定处理10Hz以下的换向计算。(Brushless motor driver source code. Program based on the sensorless brushless motor starter. Is the core to the point of view for detection: the motor back-EMF waveform data processing, through the attenuation filter, remove the zero-crossing phase. For low-speed back-EMF waveform dB is too small, waveform disturbance too, this procedure can not be stabilized to 10Hz for the following calculation.)
