Hi,
has anyone an working example with the USBUART device in DMA mode? In my Application I would like to avoid to do the data transfer by the CPU because of some other time critical tasks. So my plan was to poll a global variable or something to figure out if I received data from the host and than send an answer. I got it working with the manual Endpoint management but when i get al larger interrupt load the PC reports an error of the USB device.
I would be very glad if someone could post a example.
regards
