CCS/TMS570LC4357: eQEP1 module interrupt handle

Hello Deepak,
In HALCoGen you should do as follows:
- Enable EQEP1 driver;
- In PINMUX Tab check EQEP;
- In EQEP Tab change what needed (Compare value, Position counter mode, check Position-compare match interrupt, for example) ;
- in VIM Tab - enable eQEP1 interruipt.

In CCS;
- enable Interrupts;
- call QEPInit(); (functrion is in HL_eqep.c )
- call eqepEnableCounter(eqepREG1); (functrion is in HL_eqep.c )

Interrupt handler is in HL_eqep.c and ISR is in HL_notification.c

I hope I am not missing something.

Best regards,
Miro

Sir,
_enable_irQ_interrupt();
_enable_interrupt();
eqepEnableInterrupt(eqepReg1, QEINT_Pcm);

above functions i have included in my code along with enable counter and QEPINIT(). I have also written some logic in eQEPNotification() as ISR. But upon position compare match PCM interrupt flag is not set and eQEPNotification() is not executing.

kindly help

Hi,
Add eqepEnablePosnCompare (eqepBASE_t *eqep);

Thanks! eqepEnablePosnCompare (eqepBASE_t *eqep) added. I am unable to get how to configure the interrupt handler on position compare match interrupt only?

Hi,
QEINT is the register where eQEP interrupts are enabled/disabled. More on eQEP registers can be found in device TRM, Section 34:
www.ti.com/.../spnu563a.pdf
You can enable/disable interrupts in HALCoGen as well: EQEP-->EQEP1 Tab, Interrupt Configuration (Position-compare match Interrupt, for example).

Best regards,
Miro
