TMS320F28069M: Changing interrupt priority like told in hal_tutorial.pdf does not work

With the above settings you have shown, are you able to enter either the Timer0 or SCI-B RX interrupts?

Sean

You need to change two more things.

1. Change the interruput acknowledge function in mainISR()

  // acknowledge the ADC interrupt
  HAL_acqAdcInt(halHandle,ADC_IntNumber_1);

2. Change HAL_acqAdcInt() in hal.h file as following

static inline void HAL_acqAdcInt(HAL_Handle handle,const ADC_IntNumber_e intNumber)
{
  HAL_Obj *obj = (HAL_Obj *)handle;

  // clear the ADC interrupt flag
  ADC_clearIntFlag(obj->adcHandle,intNumber);

  // Acknowledge interrupt from PIE group 1
  PIE_clearInt(obj->pieHandle,PIE_GroupNumber_1);

  return;
} // end of HAL_acqAdcInt() function

Hey, thank you very much. Did i unterstand correctly, that i can assign any interrupt to any interrupt number? Does the PIE_Group number debend on the interrupt number or on the hardware-port where the module is connected?
Thanks!

If I'm understanding your question correctly, no, the interrupt numbers are not changable. Timer 0 interrupt can not be triggered by Timer 1 by changing a setting, and as a result, Timer 0 will only trigger Timer 0 ISR for the specific PIE Table entry that it has been assigned to.

Hi,
thank you very much for the reply! Sorry for not replying it was a stresful week.
What you said is totally clear to me. My question was about the assignment of the peripherals interrupts. If i understood the mux correctly, I have my peripheral interrupt signals and CPU interrupt numbers. And i can assign any peripheral to any Cpu interrupt number. But actually I don't really understand where exactly this assignment happens. Also Im doing bad in understanding the Interrupt groups.
Now all my Interrupts are running but ADC and the Timer module are both on CPUintNumber1. But the ADC is "HP". What i wanted to do is to give the main ISR the highest priority. The Timer and SCI should have lower priorities.
I think its totally easy to understand but im missing any link.
Following i will show you how i setup the interrupts now. What i don't like that ADC and Timer are both on CPUIntNumber1. Can this cause a problem?

Setup in Main:
// initialize the interrupt vector table
HAL_initIntVectorTable(halHandle);
// enable the ADC interrupts
HAL_enableAdcInts(halHandle);
// enable the SCIB interrupts
HAL_enableSciInts(halHandle);
// enable global interrupts
HAL_enableGlobalInts(halHandle);
// disable the PWM
HAL_disablePwm(halHandle);
// enable Timer0Interrupt , occurs every 10ms
HAL_enableTimer0Int(halHandle);

static inline void HAL_initIntVectorTable(HAL_Handle handle)
{
HAL_Obj *obj = (HAL_Obj *)handle;
PIE_Obj *pie = (PIE_Obj *)obj->pieHandle;
ENABLE_PROTECTED_REGISTER_WRITE_MODE;
pie->TINT0 = &timer0ISR;
pie->ADCINT1_HP = &mainISR;
pie->SCIRXINTB =&sciBRxISR;
DISABLE_PROTECTED_REGISTER_WRITE_MODE;

return;
} // end of HAL_initIntVectorTable() function

void HAL_enableAdcInts(HAL_Handle handle)
{
HAL_Obj *obj = (HAL_Obj *)handle;
// enable the PIE interrupts associated with the ADC interrupts
PIE_enableAdcInt(obj->pieHandle,ADC_IntNumber_1HP);
// enable the ADC interrupts
ADC_enableInt(obj->adcHandle,ADC_IntNumber_1);
// enable the cpu interrupt for ADC interrupts
CPU_enableInt(obj->cpuHandle,CPU_IntNumber_1);
return;
} // end of HAL_enableAdcInts() function

void HAL_enableSciInts(HAL_Handle handle)
{
HAL_Obj *obj = (HAL_Obj *)handle;
// enable the PIE interrupts associated with the SCI interrupts
// enable SCIB RX interrupt in PIE
PIE_enableInt(obj->pieHandle,PIE_GroupNumber_9,PIE_InterruptSource_SCIBRX);
// enable SCI RX interrupts
// enable SCIB RX interrupt
SCI_enableRxInt(obj->sciBHandle);
// enable the cpu interrupt for SCI interrupts
CPU_enableInt(obj->cpuHandle,CPU_IntNumber_9);
} // end of HAL_enableSciInts() function

void HAL_enableTimer0Int(HAL_Handle handle)
{
HAL_Obj *obj = (HAL_Obj *)handle;
PIE_enableTimer0Int(obj->pieHandle);
// enable the interrupt
TIMER_enableInt(obj->timerHandle[0]);
// enable the cpu interrupt for TINT0
CPU_enableInt(obj->cpuHandle,CPU_IntNumber_1);
return;
} // end of HAL_enablePwmInt() function

If you can see, both Timer0 and ADC are assigned to CPU_IntNumber_1...am i right with this? Actually it works fine like this.

Thank you! Yes that was the part i wasn't sure about how to understand that. But now with your explanation its clear to me. Thank you!!!
Best Regards

Sebastian
