说明：  32 F429同时使用定时器2和4实现中断控制LED0和1闪烁(USING TIM2 AND TIM4 IN THE MEANWHILE)

三种SPWM算法在MSP430单片机上的实现，内含详细的算法分析，包括对称规则采样法，不对称规则采样法，等效面积法(Three SPWM algorithm on the MSP430 MCU to achieve, including a detailed analysis of algorithms, including symmetric regular sampling method, asymmetric regular sampling method, the equivalent area method)

stm8l的ADC采集，DAC输出以及串口通讯(Stm8l ADC acquisition, DAC output and serial communication)

LPC analysis filter.Allowing wrap around so that two wraps can cancel each other. The rare cases where the result wraps around can only be triggered by invalid streams.
