At the risk of appearing dead thick, please can someone explain how I may use a Windows 7 laptop to talk to a host Xmega without loading any special drivers.
I know I will appear old fashioned, but after getting a barcode scanner to successfully talk to an AT90USB1287 working in host mode (all assembler code and with fellow freak’s help), I would love to send simple data from a COM port on my laptop to an XMEGA USB device port.
I can code the XMEGA to any simple scheme such as HID/CDC but do not know what to expect re the laptop.
If I plug in the USB cable to the laptop and power up the connected XMEGA, I assume that I will get a message saying windows is loading a built-in driver?
If this is so, if I go to ‘devices and printers’ will I see the device and how will it be identified?
One further niggle is about configuring the COM port, I would normally set bit rate etc, but in the case of USB I cannot see how this would work?
Once again, I am sorry if the questions are just silly, but any insight would be much appreciated.
