!!! 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 However, this is heavily outdated and not supported any more.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.

pas-libusb -- Object Oriented wrapper for LibUSB

libusb 0.1 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.

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 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.
