## README

!!! PLEASE USE GIT BRANCH "libusb-1.0" !!!
==========================================

The code in the "master" branch (you are looking currently) supports version
0.1 of libusb. However, this is heavily outdated and not supported any more.

Please switch to branch "libusb-1.0" for the latest and greatest Pascal
bindings for the current version of `libusb <https://libusb.info/>`_.


pas-libusb -- Object Oriented wrapper for LibUSB
================================================

`libusb 0.1 <http://www.libusb.org/>`_ provides access to USB devices in user space.

This project provides Pascal header translations plus an object-oriented
wrapper for convenience.

Note: In the current branch only the legacy version 0.1 of libusb is
supported.  The new version 1.0 introduced major changes in the API and is
supported in branch "libusb-1.0".

Directory Structure
-------------------

  ``src/``
    Header translations and OOP wrapper.

  ``src/examples/``
    Example for the direct usage of the OOP wrapper. This directory also has a
    ``Makefile``.

Build
-----

::

  $ cd src/examples/
  $ make

For further information see the comment at the top of `src/examples/testfirmware.pas
<pas-libusb/blob/master/src/examples/testfirmware.pas>`_.

Usage
-----

Simply add the units ``LibUSB`` and ``USB`` to the uses-clause of your
program. Derive from the class ``TUSBDevice`` to implement your custom driver.

The unit ``EZUSB`` provdes the class ``TUSBDeviceEZUSB`` to interface to the
Cypress EZ-USB AN2131 microcontrollers. It provides functions to access the
on-chip SRAM and to download its firmware.

Platform
--------

This project was compiled with `FreePascal <http://www.freepascal.org/>`_
2.6.0 on Linux.

Other Projects
--------------

**k7103-usb**
  The USB Interface of the Velleman k7103 PC Storage Oscilloscope
  http://k7103.sourceforge.net/ uses these units to communicate with the
  hardware.

**EZ-Tools**
  EZ-Tools is a command line tool for generic access to devices with a built
  in Cypress EZ-USB AN2131 microcontroller.
