基于wince的电力控制人机交互界面，可显示三相电压电流，设置采样变比-Wince the power to control the interactive interface to display three-phase voltage and current, set the sampling ratio

光伏并网系统 三大服务而非我基于PI控制的电流内环控制 -PV grid system three services rather than my inner current loop control based on PI control

GT2440在Wince系统下的PWM驱动，不仅可以控制PWM输出的频率和占空，还可以读取PWM当前计数器值-GT2440 in Wince system PWM drive can not only control the PWM output frequency and duty cycle, you can also read the PWM current counter value
