After working for several years, general hardware engineer will be made at home like a laboratory like, what oscilloscopes, frequency, boards or something, if you press the value and importance of points, the oscilloscope is undoubtedly second to none, the oscilloscope is what? Software engineers and hardware engineers looked at the station wonder, bottles and jars are so many, in fact, are an essential tool. Why we are the craftsmen, artisans nature can not do without a tool.
Besides oscilloscope, because the microcontroller rely on to direct the other hardware work? Well instructions. That command is what? Command is the signal. That signal is what? Signal wave is what we said before, the most important of which is a square wave signal, this square wave our eyes can not see, ah, led to a show, so high frequency, basically can not be seen, ah, so you have to the high-level tools, that is, the oscilloscope, the oscilloscope typically microsecond scan easily capture the square wave signal, sweeping all the instructions, the oscilloscope can additionally calculate the wavelength, the wavelength and frequency are related.
So, software engineers to learn the hardware, repairing several tool is indispensable, especially oscilloscope, oscilloscope has a high price, but also cheap, high price on a million have thousands, tens low price, there are hundreds of , not the same function, the accuracy is not the same, we do not need a place, you can get hold of cheap play, so what have learned about it, then get hold of high-level play.
