但是，目前没有哪个电子系统可以对如此高的振动频率计数。
But no electronic systems exist that can directly count these oscillations.
仅连接一个频率计数器到这个管脚，显示总线频率。
Just connect a frequency counter to this pin, and it will display your bus frequency.
简单的特征频率计数器，但为什么不计数发生在实时？
Simple character frequency counter, but why won't the count happen in realtime?
