hello dear forum,

I am trying to write a program for STM32F103RC but when I enable TIM8_UP interrupt the program freezes I am using RIDE7 for compiling and the program compiles without error please have a look at my code , thank you

RCC_APB2PeriphClockCmd(RCC_APB2Periph_TIM8, ENABLE); 
----------------------------- 
void
TIM8_UP_IRQHandler(
void
){ 
tim8tog++; } 
----------------------------- 
TIM_ITConfig(TIM8, TIM_IT_Update , ENABLE); 
----------------------------- 
NVIC_InitStructure.NVIC_IRQChannel = TIM8_UP_IRQn; 
NVIC_InitStructure.NVIC_IRQChannelPreemptionPriority = 0; 
NVIC_InitStructure.NVIC_IRQChannelSubPriority = 2; 
NVIC_InitStructure.NVIC_IRQChannelCmd = ENABLE; 
NVIC_Init(&NVIC_InitStructure);

Qualify and Clear the interrupt source before incrementing your counter variable.
