Endpoints are the core of the USB data transfer process. They come in a few forms such as control, isochronous, bulk, and interrupt. We won't cover the details here except with some caveats in open below. In general, data is transferred by setting up a buffer of a given length to be transferred on a given endpoint address and then waiting for an interrupt to signal that the transfer is finished. Further details below.
Endpoints within USB have an address which encodes both the number and direction of an endpoint. TinyUSB provides `edpt_number` and `edpt_dir` to unpack this data from the address. Here is a snippet that does it.
