今天用示波器测量，发现6个口的PWM频率不一样，3，9，10，11，是478HZ左右，5，6是952hz,有哪位遇到过，有没解决办法。

這是 Arduino Uno及類似board 的標準定義。

// On most Arduino boards, the PWM function is available on pins 3, 5, 6, 9, 10, and 11. The frequency of the PWM signal on most pins is approximately 490 Hz. On the Uno and similar boards, pins 5 and 6 have a frequency of approximately 980 Hz. Pins 3 and 11 on the Leonardo also run at 980 Hz.//

非常感谢你，我还以为这个芯片问题，我研究下底层代码谢谢你的回复。
