看门狗,又叫 watchdog timer,是一个定时器电路, 一般有一个输入,叫喂狗(kicking the dog or service the dog),一个输出到MCU的RST端,MCU正常工作的时候,每隔一端时间输出一个信号到喂狗端,给 WDT清零,如果超过规定的时间不喂狗(一般在程序跑飞时),WDT 定时超过,就会给出一个复位信号到MCU,是MCU复...
注意 函数 attachInterrupt(interrupt, function, mode)有3 个参数。第一个参数是中断号,可以设置为0或者1;第二个参数是中断调用的函数,必须是一个无参数无返回值的函数;第三个参数是产生中断的模式。中断模式可赋下列4种值:设置LOW时,中断在引脚电平为低时触发;设置为 CHANGE 时,中断在引脚电平改变时触发;设置...

On the next rising edge, an interrupt is fired, and the CPU suspends the main program and stops the timer. Now, the timer count can tell us the total time (T) or period of the signal. To get the frequency we’ll do (F = 1/T) and we’re done. ...
