实现的是一个虚拟示波器的功能，但只能实现模拟，不能实际测量，只需增加一个模块就行了，运行时注意不要让自动的最大值与最小值相同，否则会一直跳闪，还有就是有些功能测的不是很准确，需要调节。-Realize a virtual oscilloscope functions, but only the realization of simulation, not actual measurements, just add a module on the list, run-time attention to not to let the automatic the same maximum and minimum value, otherwise they will always jump flash, there is Some functional test is not very accurate, needs to adjust.
