now() + TimeSpan(seconds)返回未来时间,并加上当前时间的秒数。 now() - TimeSpan(days,hours, minutes, seconds)返回过去的时间。 Arduino代码–在24C32 EEPROM中读取/写入 作为奖励,使用DS3231 RTC模块,您可以获得32字节的电可擦除ROM。即使设备的主电源中断,其内容也不会被擦除。
setDebounceTime(unsigned int time) Set the amount of milliseconds the keypad will wait until it accepts a new keypress/keyEvent. This is the “time delay” debounce method. 设置键盘将等待直到接受新的keypress / keyEvent的毫秒数。这是使用“时间延迟”防止抖动方法。 addEventListener(keypadEvent) Tri...
lastTime = now; }voidSetTunings(doubleKp,doubleKi,doubleKd){ kp = Kp; ki = Ki; kd = Kd; } 其中,Compute() 在需要进行PID控制量计算的任何时候被调用,在这样的代码支持下,PID控制可以工作得很好。但是,如果是一个性能较强的工业控制器,还需要考虑一下几个问题: ...
