mc9s12 CAN wake up fail

[fupeng]

Hi,

    I am using MC9S12xet256 micrcontroller,I use the Processor Expert to create the code.In stop mode, Normally I can wake up it by CAN,but when the AD module added,I can not wake up by CAN.

   Execute the code as follows：

  main.c

for(;;)

{

   AD1_Measure(TRUE);  /*It is possible to delete these two lines*/
   AD1_GetValue16(&advalue);

   if(EnterStopFlag)

   {

      EnterStopFlag = 0;

      /*turn off led*/

      CAN1_SetSleepRequest();
      Cpu_SetStopMode();

      /*turn on led*/

   }

}

   event.c

void CAN1_OnFullRxBuffer(void)
{
   ...

   ...
   if(MessageID == 0x101)
   {
      EnterStopFlag= 1;
   }
   else
   {
      EnterStopFlag= 0;
   }
}

void CAN1_OnWakeup(void)
{
   /* Write your code here ... */
   CAN1_ClearSleepRequest();
}

Can anybody please help me reolve this issue?

Regards,

Felix

Hi,

Sorry for the late response.

I have run the project but I don't see any problem.

It always wake up regardless of ADC.
