    Documentation or example for USB-FS CDC with DMA

    DoBa_1705086

      I am seeking to enhance a current project that uses the PSOC5 full-speed USB with CDC to transfer data to a laptop.  My project currently uses the USBUART with Manual endpoint buffer management together with my own circular buffer scheme to transfer the data to the IN endpoint.  I want to change this to DMA and use the DMA completion interrupt to continue sending the next chuck of data from my circular buffer.  However I have found the USB CDC documentation to be insufficient with regard to connecting to the DMA interrupt handler.  Where might I find additional documentation or an example that uses USB CDC with DMA and DMA completion interrupt handlers?
