Did you mean to ask how to send data every microframe? You can just keep the buffers (of the associated DMA channel) full and data will be sent over as soon as the PC requests them. Also set the bInterval value (in the endpoint descriptor) to 1 so that the PC requests for data every microframe.

 You can look at the IsoSourceSink or IsoSource example projects in the [SDK Root]\firmware\basic_examples folder.

   

 

   

Alternatively, you can just modify the transport type of the GpifToUsb projec (at [SDK Root]\firmware\basic_examples\cyfxgpiftousb) to Isochronous and verify.
