TMS570學習筆記2 - RTI中斷

RTI實時中斷

• main.c

  void main(void)
  {
  	/* USER CODE BEGIN (3) */
  	/* Initialize RTI driver */
  	rtiInit();
  	/* Set high end timer GIO port hetPort pin direction to all output */
  	/* Enable RTI Compare 0 interrupt notification */
  	rtiEnableNotification(rtiNOTIFICATION_COMPARE0);
  	/* Enable FIQ - Clear F flag in CPS register */
  	/* Note: This is usually done by the OS or in an svc dispatcher */
  	_enable_IRQ();
  	/* Start RTI Counter Block 0 */
  	rtiStartCounter(rtiCOUNTER_BLOCK0);
  	/* Run forever */
  	while(1);
  	/* USER CODE END */
  }
  

• 中斷響應函數模塊

  /* USER CODE BEGIN (4) */
  /* RTI Compare 0 interrupt notification */
  void rtiNotification(unsigned notification)
  {
  	/* Toggle NHET1[0] pin */
  }
  /* GIO interrupt notification (Not used but must be provided) */
  /* ESM interrupt notification (Not used but must be provided) */
  void esmGroup1Notification(int bit)
  {
  return;
  }
  void esmGroup2Notification(int bit)
  {
  return;
  }
  /* USER CODE END */
