C++ (Cpp) Jitter1 Examples

Example #1

File: OS.c Project: tach4455/EE345M

// ******** Timer2A_Handler ************
// Updates sleep state and calls periodic function
// For lab 2 this is executing at 2kHz
void Timer2A_Handler(void) {

  Jitter1();
  TimerIntClear(TIMER2_BASE, TIMER_TIMA_TIMEOUT);
  gTimer1Count++;

  
  if(gThread1Valid == VALID) {
    gThread1p(); // Call periodic function
  }
}
