TIMER interrupt in STR912

rupesh vishwakarma

Hi I aam sending code for timer problem is that code goes inside handler for a long time (till then LED is off)
please suggest the right code

void main(void)
{

  #ifdef DEBUG
    debug();
  #endif

  SCU_APBPeriphClockConfig(__TIM01, ENABLE); /* Enable the clock for TIM0 and TIM1 */
  TIM_DeInit(TIM0);                          /* TIM0 Deinitialization */

  SCU_APBPeriphClockConfig(__TIM23, ENABLE); /* Enable the clock for TIM2 and TIM3 */
  TIM_DeInit(TIM2);                          /* TIM2 Deinitialization */


   SCU_APBPeriphClockConfig(__GPIO9, ENABLE);
  /* GPIO Structure Initialization */
  GPIO_StructInit(&GPIO_InitStructure);
        SCU_AHBPeriphClockConfig(__VIC,ENABLE);
        SCU_AHBPeriphReset(__VIC,DISABLE);
        VIC_DeInit();
        VIC_Config(TIM2_ITLine, VIC_IRQ, 0);
        VIC_ITCmd(TIM2_ITLine, ENABLE);

   /*GPIO9 for LED*/
        GPIO_DeInit(GPIO9);
        GPIO_InitStructure.GPIO_Direction = GPIO_PinOutput;
        GPIO_InitStructure.GPIO_Pin = GPIO_Pin_0|GPIO_Pin_1 ;
        GPIO_InitStructure.GPIO_Type = GPIO_Type_PushPull ;
        GPIO_Init (GPIO9, &GPIO_InitStructure);
        GPIO_WriteBit(GPIO9, GPIO_Pin_0, Bit_RESET);
          GPIO_WriteBit(GPIO9, GPIO_Pin_1, Bit_RESET);


   /*TIM2 Structure Initialization*/
        TIM_StructInit(&TIM_InitStructure);
        TIM_InitStructure.TIM_Mode = TIM_OCM_CHANNEL_1;
         TIM_InitStructure.TIM_OC1_Modes = TIM_TIMING;
        TIM_InitStructure.TIM_Clock_Source = TIM_CLK_APB;
        TIM_InitStructure.TIM_Prescaler = 0xFFFF;
        TIM_InitStructure.TIM_Pulse_Length_1 = 0xFF;
        TIM_Init (TIM2, &TIM_InitStructure);
        //TIM_ITConfig(TIM2, TIM_IT_TO, ENABLE);


         TIM_ITConfig(TIM2, TIM_IT_TO, ENABLE);
         TIM_ITConfig(TIM2, TIM_IT_OC1, ENABLE);
         //Delay(0xFCD);
         GPIO_WriteBit(GPIO9, GPIO_Pin_1, Bit_SET);
        //GPIO_WriteBit(GPIO9, GPIO_Pin_1, Bit_RESET);

                TIM_CounterCmd(TIM2, TIM_START);


}


void TIM2_IRQHandler(void)
{
           TIM_ClearFlag(TIM2, TIM_FLAG_TO);
        GPIO_WriteBit(GPIO9, GPIO_Pin_1, Bit_RESET);
                VIC0->VAR = 0;                         /*Acknowledge Interrupt  */
 //     VIC1->VAR = 0;
