hi,

I am new to ARM processors. I am using Discovery F4 Kit. I need the explanation if this code.

#if defined(TM_DELAY_TIM)
void TM_DELAY_INT_InitTIM(void);
#endif

#if defined(TM_DELAY_TIM)
void TM_DELAY_TIM_IRQ_HANDLER(void) { // this bracket is confusing me i can't find itS closing end i the compiled code
TIM_ClearITPendingBit(TM_DELAY_TIM, TIM_IT_Update);
#elif defined(KEIL_IDE)
void TimingDelay_Decrement(void) {
#else
void SysTick_Handler(void) {
#endif
TM_Time++;
if (TM_Time2 != 0x00) {
TM_Time2--;
}

/* Call user function */
TM_DELAY_1msHandler();
}
