Arduino 上使用定时中断，库文件来自Timer.h，把其中的这几个.cpp和.h文件下下来，并放置到library的folder中。

测试的sketch如下：

#include <Wire.h>//#include <HMC5883L.h>#include <ADXL345.h>#include <L3G4200D.h>#include "Event.h"#include "Timer.h"/*Redefine*/L3G4200D GYRO;ADXL345  ACC;Timer task;/*Define*/struct Sensor{  float x;  float y;  float z;  signed long x_sum;  signed long y_sum;  signed long z_sum;  signed short x_offset;  signed short y_offset;  signed short z_offset;}Gyro,Acc;#define Sensor_offset_times  250#define TRUE  1#define FALSE 0byte Sensor_offset_OK = FALSE;/*Function for initial sensor*/void Sensor_init(void){  GYRO.enableDefault();  //Init GYRO  ACC.enableDefault();    //Init ACC}/*Function for update sensor data*/void Sensor_update(void){  GYRO.read();  ACC.read();    if(Sensor_offset_OK){    Gyro.x = GYRO.g.x - Gyro.x_offset;    Gyro.y = GYRO.g.y - Gyro.y_offset;    Gyro.z = GYRO.g.z - Gyro.z_offset;    Acc.x = ACC.a.x - Acc.x_offset;    Acc.y = ACC.a.y - Acc.y_offset;    Acc.z = ACC.a.z - Acc.z_offset;  }  else  {    static int Sensor_offset_count = 0;    Gyro.x_sum += GYRO.g.x;    Gyro.y_sum += GYRO.g.y;    Gyro.z_sum += GYRO.g.z;    Acc.x_sum += ACC.a.x;    Acc.y_sum += ACC.a.y;    Acc.z_sum += ACC.a.z;    Sensor_offset_count ++;    if(Sensor_offset_count > Sensor_offset_times)    {      Gyro.x_offset = Gyro.x_sum / 250;      Gyro.y_offset = Gyro.y_sum / 250;      Gyro.z_offset = Gyro.z_sum / 250;      Acc.x_offset = Acc.x_sum / 250;      Acc.y_offset = Acc.y_sum / 250;      Acc.z_offset = Acc.z_sum / 250;      Sensor_offset_OK = TRUE;    }  }}/*Function for PIT task*/void PIT_5_task(void){  static int PIT_1000_task = 0;  Sensor_update();//run every 5 ms  ACC.read();  Serial.println(ACC.a.x);  /*  PIT_1000_task ++;  if(PIT_1000_task > 200)  {    PIT_1000_task = 0;    Serial.println(ACC.a.x);  }  */}/*Function for system setup*/void setup(void){  Serial.begin(19200);  Wire.begin();          //start iic This step is very important!  //ACC.enableDefault();  Sensor_init();  //MsTimer2::set(5, PIT_5_task); // 500ms period  //MsTimer2::start();}void loop(void){  //Serial.println(ACC.a.x);  //ACC.read();  //Serial.println(ACC.a.x);  delay(100);}

这段代码compiler的时候会出现问题，提示：'Timer' does not name a type

从网上google了很多人的办法都没用，自己就试着改改，我猜是Timer在其他头文件中可能被涉及到了，所以吧Timer的文件全部换个名字，改为Timer3，果然，这个定时中断就通过了。共享~记录~
