cc2530之定时器1(*模式,中断模式)

1、查看中断图

2、配置定时器1

T1CTL = 0x0d;	//设置为128分频，选择*运行模式

TIMIF = 0x40; //设置了 TIMIF.OVFIM,让定时器1产生中断

IRCON = 0x00; //清理中断标志位

EA = 1; //打开总中断

T1IE = 1; //打开定时器T1中断

3、总体代码

#include<ioCC2530.h>

#define D3LED P1_0
#define D4LED P1_1

#define LedOpen 1
#define LedClose 0

int times = 0;      //产生中断的次数
void delay(int ms)  //延时函数
{
  int i,j;
  for(i=0; i<ms; i++)
    for(j=0; j<120; j++);
}

void initT1()
{
  T1CTL = 0x0d;	//设置为128分频，选择*运行模式
  TIMIF = 0x40; //设置了 TIMIF.OVFIM,让定时器1产生中断
  EA = 1; //打开总中断
  T1IE = 1; //打开定时器T1中断
  IRCON = 0x00; //清理中断标志位
}

void initLED()
{
  P1SEL |= 0x00;      //设置为通用io模式
  P1DIR |= 0x03;      //设置成输出状态
  D3LED = LedClose;	//灯的初始状态是关闭的
  D4LED = LedClose;
}

void main()
{
  initLED();	//初始化led灯
  initT1();	   //初始化定时器1
  while(1)
  {
    switch (times)
    {
      case 1:
        D3LED = !D3LED;		//灯3亮
        D4LED = !D3LED;		//灯4灭
        break;
      case 2:
        D3LED = LedOpen;	//亮
        D4LED = LedOpen;	//亮
        break;
      case 3:
        D3LED = LedClose;	//灭
        D4LED = LedClose;	//灭
        break;
    }
  }
}
