Synchronize eCAP and ePWM

Hello,

I want to program eCAP to output a pulse every 50usec.

Exactly 3 usec after this pulse (used to trigger an external A2D convert start) I want to start an ePWM period (up/down).

Is it possible to synchronize those 2 peripherals ?

Thanks,

Zvika

Which device are you using?

Sorry. The device is TMSF28335

The first ecap signal can be 3 usec before the end of the first PWM period.

Thanks,

Zvika

Can you feed your eCAP generated pulse into the EPWMxSYNCI input? That is probably the easiest way to sync things up.
