 Hi Khrisna,

We are using FX3 to develop a USB camera. At the end of every frame we send an interruption from GPIF to ARM to perform some tasks.

I found the solution using     CyU3PGpifRegisterCallback (&cbFunction); and CYU3P_GPIF_EVT_SM_INTERRUPT event.

Regards,

Israel

Are you referring to the FW_TRIG GPIF action?

Jake,

I think it is INTR_CPU action.
