TIM_OCMode_Timing模式

XINSHOU0 · 发表于 2013-12-2 17:11:23

keil MDK4.12能否进行定时器TIM_OCMode_Timing模式仿真？？？？我写了程序，连续检查了4天，看了一些网上程序，包括stm32自带的程序，论坛中的程序也看了，就是不能进入捕获比较中断，跪求解释！！

#include "stm32f10x_lib.h" //包含了所有的头文件
void RCC_Configuration(void);
void NVIC_Configuration(void);
void GPIO_Configuration(void);
void TIM_Configuration(void);

int main(void)
{

#ifdef DEBUG
debug();
#endif

RCC_Configuration();    //使能外设时钟
GPIO_Configuration();   //初始化GPIO管脚
  NVIC_Configuration(); //中断优先级设置
  TIM_Configuration()
while(1);
}

//--------Tim2设置---------------------------
void TIM_Configuration(void)
{

TIM_TimeBaseInitTypeDef TIM_TimeBaseStructure;
TIM_OCInitTypeDef TIM_OCInitStructure;

TIM_DeInit(TIM2);
TIM_TimeBaseStructure.TIM_Period = 400;
TIM_TimeBaseStructure.TIM_Prescaler = 35999;
TIM_TimeBaseStructure.TIM_ClockDivision = 0x0; //设置时钟分割系数
TIM_TimeBaseStructure.TIM_CounterMode = TIM_CounterMode_Up; //向上计数
TIM_TimeBaseInit(TIM2,&TIM_TimeBaseStructure);

TIM_OCInitStructure.TIM_OCMode = TIM_OCMode_Timing;
TIM_OCInitStructure.TIM_Channel = TIM_Channel_1;
TIM_OCInitStructure.TIM_Pulse = 200;
TIM_OCInitStructure.TIM_OCPolarity = TIM_OCPolarity_High;
TIM_OC1Init(TIM2, &TIM_OCInitStructure);

TIM_ITConfig(TIM2, TIM_IT_CC1, ENABLE ); //使能中断
TIM_InternalClockConfig(TIM2); //配置 TIM 的内部时钟
TIM_Cmd(TIM2,ENABLE);//使能TIM2
}

//----------GPIO设置--------------------------
void GPIO_Configuration(void)
{
GPIO_InitTypeDef GPIO_InitStructure;
GPIO_DeInit(GPIOA);    //初始化

GPIO_InitStructure.GPIO_Pin = GPIO_Pin_0;
GPIO_InitStructure.GPIO_Speed = GPIO_Speed_10MHz;
GPIO_InitStructure.GPIO_Mode = GPIO_Mode_Out_PP;    // 推挽输出
GPIO_Init(GPIOA,&GPIO_InitStructure);
}
//-------------设置时钟72mhz------------------------------
void RCC_Configuration(void)
{
RCC_DeInit();    //初始化
RCC_HSEConfig(RCC_HSE_ON);   //时钟使能
while (RCC_GetFlagStatus(RCC_FLAG_HSERDY) == RESET); //等待高速时钟就绪
FLASH_PrefetchBufferCmd(FLASH_PrefetchBuffer_Enable);
FLASH_SetLatency(FLASH_Latency_2);
RCC_HCLKConfig(RCC_SYSCLK_Div1);
RCC_PCLK2Config(RCC_HCLK_Div1);
RCC_PCLK1Config(RCC_HCLK_Div2);
RCC_PLLConfig(RCC_PLLSource_HSE_Div1, RCC_PLLMul_9); ////使用锁相环输出72Mhz
RCC_PLLCmd(ENABLE);        // Enable PLL
while(RCC_GetFlagStatus(RCC_FLAG_PLLRDY) == RESET); // Wait till PLL is ready
RCC_SYSCLKConfig(RCC_SYSCLKSource_PLLCLK);
while(RCC_GetSYSCLKSource() != 0x08);

RCC_APB1PeriphClockCmd(RCC_APB1Periph_TIM2,ENABLE);//开启定时器2时钟
RCC_APB2PeriphClockCmd(RCC_APB2Periph_GPIOB|RCC_APB2Periph_GPIOA, ENABLE); // 使能外设时钟
}

----------------------------------------------
void NVIC_Configuration(void)
{
NVIC_InitTypeDef NVIC_InitStructure;
NVIC_DeInit();
NVIC_PriorityGroupConfig(NVIC_PriorityGroup_1);
NVIC_InitStructure.NVIC_IRQChannel = TIM2_IRQChannel;
NVIC_InitStructure.NVIC_IRQChannelPreemptionPriority = 0;
NVIC_InitStructure.NVIC_IRQChannelSubPriority = 7;
NVIC_InitStructure.NVIC_IRQChannelCmd = ENABLE ;
NVIC_Init(&NVIC_InitStructure);
}
-------------中断函数---------------------------
char a=0x00;
void TIM2_IRQHandler(void)
{
a=~a;
GPIOA->ODR=(a&0x01);
TIM_ClearITPendingBit(TIM2, TIM_IT_CC1); // 清除中断标志位
}

原子的《标准例程-V3.5库函数版本》程序中是否有TIM_OCMode_Timing模式的，我看到里面有定时器中断实验、

WM输出实验

回复【2楼】XINSHOU0:
---------------------------------
有输入捕获模式.
没有OCMode_Timing的

哦，对不起原子哥，打错了，库函数中如下：

/* TIM Output Compare and PWM modes -----------------------------------------*/

#define TIM_OCMode_Timing                  ((u16)0x0000)    // TIM输出比较时间模式
#define TIM_OCMode_Active                  ((u16)0x0010)
#define TIM_OCMode_Inactive                ((u16)0x0020)
#define TIM_OCMode_Toggle                  ((u16)0x0030)
#define TIM_OCMode_PWM1                    ((u16)0x0060)
#define TIM_OCMode_PWM2                    ((u16)0x0070)

求原子哥、大神们指点，万分感谢！
