Detecting an USB IN request

[Anonymous]

What I want to do is have an interrupt triggered, or some other method when an USB IN request is recieved. I then want to be able to commit the data to the endpoint to be sent out. 

       

Thanks

Hi Jon,

   

I don't think we have a way to identify the IN token in FX3.

   

For committing data to USB, it will be done automatically if you are using AUTO DMA channel and we need to commit the data using CyU3PDmaChannelCommitBuffer when there is a producer event if you are using MANUAL DMA channel to transfer data from GPIF II to USB.

   

Thanks,

In FX2 there was a host of interrupts that were generated for different events, such as SOF. Is it not possible to so the same in FX3?

       

Thanks
