Has anyone used feedback endpoints on a FX2LP and can post an example.

Thanks

Jon

 I am creating a USB audio speaker device. I want to use an isochronous async endpoint. So I will have an OUT endpoint for the speaker audio data and an IN endpoint that is the feedback endpoint. So I am wondering if there any examples for the FX2LP device.

Thanks

Jon

 Hi,

If I'm not mistaken, you need to send an acknowledge packet to Host for each ISOC out transfer. I dont have an example project with me, but we have an example project for Bulk transfer,  refer  section "Endpoint Interrupts" in AN78446 http://www.cypress.com/?docID=36642.
