USB is a complicated topic with uCs that implement it internally. And it sounds like your doing three things at once. We've just been discussing how cryptic uC manufacturers code can be.
My suggesting is to build a few things that don't include USB first. Get fluent with dealing with structs, function pointers, the DMA and the like, and the Atmel software framework. Then come back to USB when you're just learning that, not a whole new set of things. The USB communication can be divided into two parts, setup and operation.
Setup is when the device enumerates, i. Note that since USB is host-directed, the device cannot just send the data, it has to wait for the host to request for it. Pages: [ 1 ] Go Up. There was an error while thanking. SMF 2.
