2015年电赛国测题，频率测量。基于stm32的频率测量。优点：精密度高，代码简单(In 2015, the National Test of Electricity Competition, Frequency Measurement. Frequency measurement based on stm32. Advantages: High precision, simple code)

说明：  传感器驱动代码，温差式压力传感器，用来测量气体流量(Sensor drive code, temperature differential pressure sensor for measuring gas flow)

msp430芯片内部ad12模数转换程序源码。。(MSp430 chip internal Ad12 analog-to-digital conversion program source code.)

一个DC-AC-DC的变换器，通过DC-AC的前级串联，AC-DC的后级并联，降低了MOSFET的电压应力，若采用交错控制技术，可大大减少输出电流纹波，可提高变换器的功率密度.(A DC-AC-DC converter, through the front stage series DC-AC, and the parallel of AC-DC, reduced MOSFET voltage stress, if the interleaving control technology, which can greatly reduce the output current ripple, can increase the power density of the converter. )
