Will the PIE11 be taken by the main CPU when CLA EPWM task completes ?

Other Parts Discussed in Thread: CONTROLSUITE

Dear All,

About the PiccoloB CLA Configure register, it can only access at the c2000 CPU. I think to modify the CLA register at the PIE(INT11).

I have one experience what can not into PIE(CLA1_INTx ISR) when CLA Task(EPWM) completes.

My code CLA1_INT1 source is from EPWM1. I testified that the CLA Task1 had come in. But can not in to the (as below)breakpointer of the INT11.1 when the Task1 complete. Anyone have this happened to you?

PS:The controlSUITE example project "Example_2803xClaAdcFir" CLA1_INT7 from ADC. This can run to "interrupt void cla1_isr7()" when the CLA Task7 completes.

My Initialize :

   EALLOW;
   PieVectTable.CLA1_INT2 = &cla1_isr1;
   EDIS;

   EALLOW;
   PieCtrlRegs.PIEIER11.bit.INTx1 = 1;
   EPwm1Regs.CMPA.half.CMPA = 62;
   EPwm1Regs.ETSEL.bit.INTSEL = ET_CTR_ZERO;
   EPwm1Regs.ETSEL.bit.INTEN = 1;
   EPwm1Regs.ETPS.bit.INTPRD = ET_1ST;
   EPwm1Regs.ETCLR.bit.INT = 1;

   Cla1Regs.MPISRCSEL1.bit.PERINT1SEL = CLA_INT1_EPWM1INT;

   IER |= M_INT11;
   EINT;
   ERTM;
   EDIS;


   interrupt void cla1_isr1()
   {

      PieCtrlRegs.PIEACK.all = PIEACK_GROUP11; /* set breakpointer here*/
   }

Hi Eric,

I think you have assigned the address of the isr i.e. cla1_isr1 to the wrong interrupt vector

PieVectTable.CLA1_INT2 = &cla1_isr1;

It should be PieVectTable.CLA1_INT1 = &cla1_isr1; since you want task 1 to hit the interrrupt service routine on completion

Hi Vishal,

Sorry, this word is key wrong, but my code is "PieVectTable.CLA1_INT1 = &cla1_isr1;"

Have you one example code for the PWM CLA task and the PIE11 ISR? I cannot find at the controlSUITE. Or, Where download ?

Best Regards

Eric

Hi Vishal,

I verify ok for the function PWM CLA task1 and PIE11 ISR, when I buit new project for the CLA_PWM.

Eric,

There are also some Cla examples in controlsuite. If you have downloaded the f28035 header files, you can find them under C:\TI\controlSUITE\device_support\f2803x\vZZZ\DSP2803x_examples_ccsv4. There should be three examples, cla_adc, cla_adc_fir and cla_adc_fir_flash.

The cla_adc example uses the EPWM to trigger an ADC conversion which then triggers one of the CLA tasks.This might be a useful template for what you are doing.Hope it helps
