# USB2 High Speed Core
This core is a customization of the [LUNA project](https://github.com/greatscottgadgets/luna),
which is a USB analyzer.

The aim of this project is to strip down the original project to
its USB2 highspeed-capable core which is easy to integrate into your own
FPGA project.

## Notable differences to the LUNA project

This project implements stream based isochronous
in and out endpoints:
* [USBIsochronousInStreamEndpoint](https://github.com/hansfbaier/usb2-highspeed-core/blob/main/luna/gateware/usb/usb2/endpoints/isochronous.py#L219)
* [USBIsochronousOutStreamEndpoint](https://github.com/hansfbaier/usb2-highspeed-core/blob/main/luna/gateware/usb/usb2/endpoints/isochronous.py#L401)

This project includes the following examples:
* [USB2 class compliant high speed audio interface](https://github.com/hansfbaier/usb2-highspeed-core/blob/main/examples/usb2_audio.py)

## Project Structure

This project is broken down into several directories:

* `luna` -- the primary LUNA python toolkit; generates gateware and provides USB functionality
  * `luna/gateware` -- the core gateware components for LUNA; and utilities for stitching them together
* `examples` -- simple LUNA-related examples; mostly gateware-targeted, currently
* `docs` -- sources for the LUNA Sphinx documentation
* `applets` -- pre-made gateware applications that provide useful functionality on their own (e.g., are more than examples)

## Project Documentation

LUNA's documentation is captured on [Read the Docs](https://luna.readthedocs.io/en/latest/). Raw documentation sources
are in the `docs` folder.
