[Arduino]Day-10-Timer1

要記得將TimerOne解壓到Libiary資料夾裡面
基本上，可以從序列埠看到一秒顯示一次

Ardunio只有三個Timer
分別為Timer0,1,2
其中0是8bit,1是16Bit,2是8Bit



////////////////////////////////////////////////

#include <TimerOne.h>

int Timer_count = 0;

void setup()
{
  Serial.begin(9600);
  Serial.println("Serial ready" ) ;

  Timer1.initialize(1000000); // 1000000 = 1sec, set a timer of length 1 sec
  Timer1.attachInterrupt( timer_1_Isr ); // attach the service routine here

}
/// --------------------------
/// Loop Routine

void loop()

}

/// --------------------------
/// Custom ISR Timer Routine
/// --------------------------
void timer_1_Isr(void)
{
  Timer_count++;
  Serial.print("Timer_count = ");
  Serial.println(Timer_count);

}
