level interrupts in motorware_12

Till now , I haven't success configurated PWM_TZINT. any way I try!——

Yanzhen,

There are two options for these interrupts.  Group 1 only has ADCINT1, ADCINT2, and ADCINT9.  Group 10 has all 8 ADC interrupts.  Motorware is designed to use group 10 because they need to use all of the different ADC interrupts.  Certainly if you need three high priority ADC interrupts you should use group 1.

You are looking in the right place.  CPU_enableInt needs to be changed as you have already done, but PIE_enableAdcInt also needs to be changed.  If you dig a little deeper you would find that in /drivers/adc/src/32b/f28x/f2806x/adc.h there are high priority interrupt enumerations that you can use to replace ADC_IntNumber1.  Try using ADC_IntNumber_1HP.

BR,

hi:BR

In motorware , mainISR() should be highest level interrupt in system. because, other peripherals should use lower interrupts resouce.

 I remember it uses group1 in controlsuit . so I need detail process how chang.

In motorware. other peripherals configurations API less can used. so I must establish them myself. . It hard to me...

last post I want use PWM_TZINT.  .but fail. In the future I will use SCI. I2C. or capture interrupt. I must know how to use interrupt in motorware. so....I want to know why I was fail..where was wrong!

can you do PWM_TZINT .? if it is ok. show me!

Hi: Tray

I changed these:

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_1HP);

  // enable the cpu interrupt for ADC interrupts
  CPU_enableInt(obj->cpuHandle,CPU_IntNumber_1);

  return;
} // end of HAL_enableAdcInts() function

and:

 // acknowledge the ADC interrupt
  HAL_acqAdcInt(halHandle,ADC_IntNumber_1HP);

but It doesn't work!

where place do I need chang also ?

and:

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 10
  PIE_clearInt(obj->pieHandle,PIE_GroupNumber_1);

  return;
} // end of HAL_acqAdcInt() function

Hello Yanzhen Fu,

Please try:

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

Also you need to modify the code inside HAL_acqAdcInt() -> I saw that you have modified it.

But please call  HAL_acqAdcInt(halHandle,ADC_IntNumber_1); instead of   HAL_acqAdcInt(halHandle,ADC_IntNumber_1HP);

Best regards,

Maria

hi; Maria.

thanks your reply. but It doesn't work either. I use hv_kit  try it . I don't know why . can you try it?

yes,Maria.

I have done. I changed :

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->ADCINT1 = &mainISR;
  pie->ADCINT_1HP = &mainISR;

  DISABLE_PROTECTED_REGISTER_WRITE_MODE;

return;

}

thanks !

How about PWM_TZINT? I need API.

yanzhen fu said:

  pie->ADCINT_1HP = &mainISR;

I think you should keep it as pie->ADCINT1 = &mainISR;

Anyway, I will try next week and let you know.

Best regards,

Maria

Hello Yanzhen Fu,

I have tried to use ADC Int from PIE group 1 (not 10), and I can see that gLEDcnt in expression window (that is put in mainISR) are changing (which means the interrupt occurs). I used my own board (not the controlCard) so I can not see the LED blinking or not (but I am sure it is).

The modifications are:

hal.c

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_1);
    PIE_enableAdcInt(obj->pieHandle, ADC_IntNumber_1HP);     // for testing ADC int

    // enable the ADC interrupts
    ADC_enableInt(obj->adcHandle, ADC_IntNumber_1);

    // enable the cpu interrupt for ADC interrupts
    //CPU_enableInt(obj->cpuHandle, CPU_IntNumber_10);
    CPU_enableInt(obj->cpuHandle, CPU_IntNumber_1); // for testing ADC int

    return;
} // end of HAL_enableAdcInts() function

hal.h

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->ADCINT1 = &mainISR;
  pie->ADCINT_1HP = &mainISR;    // for testing ADC int

  DISABLE_PROTECTED_REGISTER_WRITE_MODE;

  return;
 } // end of HAL_initIntVectorTable() function

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 10
 // PIE_clearInt(obj->pieHandle,PIE_GroupNumber_10);
  PIE_clearInt(obj->pieHandle,PIE_GroupNumber_1); // for testing ADC int

  return;
} // end of HAL_acqAdcInt() function

If you have done the same, I don't have any idea why these modifications don't work in your board.

Hope you can figure it out (ah, sorry, I misunderstood, seems that you have made this working, that's great!)

Also I have another ISR (SCI and timer2) beside mainISR and they works fine.

I will try about the TZ interrupt.

Best regards,

Maria

I have tried PWM TZ interrupt and the answer is in your previous thread: http://e2e.ti.com/support/microcontrollers/c2000/f/902/t/337490.aspx

Best regards,

hi : maria

thanks your testing!

I try TZ interrupt. like these

   // enable the TZ1 interrupts
   HAL_enableTz1Ints(halHandle);

in Hal.c:

void HAL_enableTz1Ints(HAL_Handle handle)
{
 HAL_Obj *obj = (HAL_Obj *)handle;
 PIE_Obj *pie = (PIE_Obj *)obj->pieHandle;

 // enable the PIE interrupts associated with the TZ1 interrupts
 PIE_enableTzInt(obj->pieHandle,PWM_Number_1);     //PWM_Number_1=0;

 // enable the Tz interrupts
 Tz_enableInt(obj->pwmHandle[PWM_Number_1]);

//  PWM_enableTripZoneSrc(obj->pwmHandle[PWM_Number_1],PWM_TripZoneSrc_OneShot_TZ1_NOT);

    // enable the cpu interrupt for EPWM1_TzINT
    CPU_enableInt(obj->cpuHandle,CPU_IntNumber_2);

return;

}

in pie.c:

void PIE_enableTzInt(PIE_Handle pieHandle,const  PWM_Number_e pwmNumber)   //新增
{
   PIE_Obj *pie = (PIE_Obj *)pieHandle;
   uint16_t index = 1;
   uint16_t setValue = (1 << pwmNumber);

   // set the value
   pie->PIEIER_PIEIFR[index].IER |= setValue;

   return;
}

In pwm.c :

void Tz_enableInt(PWM_Handle pwmHandle)
{
 PWM_Obj *pwm = (PWM_Obj *)pwmHandle;
 ENABLE_PROTECTED_REGISTER_WRITE_MODE;

 //set the bits
 pwm->TZEINT |= 0x04;

 DISABLE_PROTECTED_REGISTER_WRITE_MODE;

 return;
}

In Hal.h:

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->ADCINT_1HP = &mainISR;

  DISABLE_PROTECTED_REGISTER_WRITE_MODE;
 
  ENABLE_PROTECTED_REGISTER_WRITE_MODE;

  pie->EPWM1_TZINT =&ipmISR;

  DISABLE_PROTECTED_REGISTER_WRITE_MODE;

  return;
 } // end of HAL_initIntVectorTable() function

in mymain.c:

interrupt void ipmISR(void)    //变频器硬件故障
{
  HAL_Obj *obj1 = (HAL_Obj *)halHandle;
   // close 244
   GPIO_setLow(obj1->gpioHandle,GPIO_Number_17);

   HAL_acqTzInt(halHandle,PWM_Number_1);

}

In Hal.h:

static inline void HAL_acqTzInt(HAL_Handle handle,const PWM_Number_e pwmNumber)
{
 HAL_Obj *obj = (HAL_Obj *)handle;
 TZ_clearIntFlag(obj->pwmHandle[pwmNumber]);
   // Acknowledge interrupt from PIE group 2
    PIE_clearInt(obj->pieHandle,PIE_GroupNumber_2);

}

In pwm.h:

static inline void TZ_clearIntFlag(PWM_Handle pwmHandle)
{
 PWM_Obj *pwm = (PWM_Obj *)pwmHandle;

 //set the bits
 pwm->TZCLR = PWM_TZCLR_INT_BITS;
 pwm->TZCLR = PWM_TZCLR_OST_BITS;

 return;

}

in main.h:

interrupt void mainISR(void);
interrupt void ipmISR(void);

in hal.h:

extern void HAL_enableTz1Ints(HAL_Handle handle);

in pwm.h:

//! \brief    Enables the TZ interrupt
extern void Tz_enableInt(PWM_Handle pwmHandle);

end,

but it doesn't work. !

Yanzheng

thanks!

oh: let me look and try. thanks maria.!
