"xfer" is short for "transfer". **This is one of the core methods you must implement for TinyUSB to work (one other is the interrupt handler).** Data from the host is the OUT direction and data to the host is IN. It is used for all endpoints including the control endpoint 0. Make sure to handle the zero-length packet STATUS packet on endpoint 0 correctly. It may be a special transaction to the peripheral. |
