I have searched the forums for some light on the matter of USB peripherals talking direct to an ATXMEGA. As I understand it, the peripheral (in my case a barcode scanner) is the Slave and this expects to talk to a USB Master.
But such an arrangement is not possible.
I understand this is because of the processing speed required? If my assumptions are right - is this not a crazy situation? There must be many designers out there wanting to use a slow peripheral like a keyboard or scanner not being able to use the USB port of the ATXMEGA even though the speed requirement is low and the data to be transferred simple?
Is there any solution to this problem apart from using the rapidly dating keyboard wedge or RS232 interface?
Any guidance on this would be much appreciated.
On an aside, very glad to see the documentation of the ATXMEGA chips is improving and so are the chips "“ they really are very, very good when they work "“ especially when programmed in ASSEMBLER!!!
