说明：  STM32的PWM输出模式，STM32的TIM1模块是增强型的定时器模块，天生就是为电机控制而生，可以产生3组6路PWM，同时每组2路PWM为互补，并可以带有死区，可以用来驱动H桥。(STM32' s PWM output mode, STM32' s TIM1 module is enhanced timer module, is inherently for the motor control, it can produce three groups 6-channel PWM, while the complementary PWM each 2-way, and can be with the dead zone, can be used to drive H-bridge.)

基于ARM的三相电电能计量测量程序，包括配置，初始化，显示。( Three-phase electric power metering)

ARM监视串行口，将接收到的字符发送到字符再发送给串口，即按PC机键盘通过超级终端发送数据，开发板将接收到的数据再返还给PC，在超级终端上显示。(ARM monitors the serial port, the received characters are sent to a character and then sent to the serial port, ie the PC keyboard to send data via HyperTerminal, the board will receive the data and then back to the PC, in the HyperTerminal display.)
