Hi,
I'm trying to implement a mouse and keyboard via my LPC2378 ARM chip. I have the mouse working correctly using the Keil USB classes. How would I go about implementing the keyboard side on the same USB bus? I know there is a way to create multiple configuration descriptors, however, I don't see any examples. Please lend any assistance!
Thanks!
take a look here. The appnote explains USB in general.\ http://www.keil.com/appnotes/docs/apnt_195.asp
I wrote detailed introduction for USB keyboard implementation on this topic. It will much more help you than above app note.
