(2)注意 Servo.h 库与 TimerOne 都是使用内部定时器 timer1 会影响pin 9, pin 10 的 PWM (3)tone()使用 timer2 定时器; 若使用 Tone 库的 Tone 对象(Tone 变量)也是优先使用 timer2 定时器,若用两个 Tone 变量则 timer1 也会被用掉, 用三个 Tone 则连控制 millis( )的 timer0 也会被用掉。

System timer does that job, and does indeed correct the time so it does not go back to 0 on the limit you mentioned Do you mean that if I restore the pointer then I will get the full 32 bits in millis() ? I'll give it a try. ...
The HAL bases all timing on the Arduino micros() timer, which has a platform-specific granularity and accuracy, and is based on the primary microcontroller clock. If using an internal oscillator that is less than 100ppm accurate but better than 4000 ppm accurate, or if your other loop() pr...
