Open Source C Hardware Platforms

Library to enable user space application programs to communicate with USB devices

The "Open On-Chip Debugger" provides JTAG/SWD access from GDB (or directly with TCL scripts) to processors with ARM and MIPS based cores. See website for full list of supported targets.

libusb is a library for USB device access from Linux, macOS, Windows, OpenBSD/NetBSD, Haiku and Solaris userspace. It is written in C (Haiku backend in C++) and licensed under the GNU Lesser General Public License version 2.1 or, at your option, any later version. libusb is a C library that provides generic access to USB devices. It is intended to be used by developers to facilitate the production of applications that communicate with USB hardware. Using a single cross-platform API, it provides access to USB devices on Linux, macOS, Windows, etc. No special privilege or elevation is required for the application to communicate with a device. All versions of the USB protocol, from 1.0 to 3.1 (latest), are supported. libusb is abstracted internally in such a way that it can hopefully be ported to other operating systems.

Alternative firmware for ESP8266 with easy configuration using webUI, OTA updates, automation using timers or rules, expandability and entirely local control over MQTT, HTTP, Serial or KNX. Unless your Tasmota powered device exhibits a problem or you need to make use of a feature that is not available in the Tasmota version currently installed on your device, leave your device alone - it works so don't make unnecessary changes! If the release version (i.e., the master branch) exhibits unexpected behaviour for your device and configuration, you should upgrade to the latest development version instead to see if your problem is resolved as some bugs in previous releases or development builds may already have been resolved. Single binary firmware. Support for TuyaMCU. Increase PWM channels to 16. Initial support for ESP32S3 with support for 38 configurable GPIOs.

libmylcd is a frame & font rendering library and toolkit designed to provide low level access to 2D hardware via a video framebuffer. Supported devices include SED133x, T6963C, PCD8544, S1D15G10, USBD480, PCF8833, PCF8814, USB13700, S1D15G14.

serialconsole (sc) is a minimal terminal program allowing to use one machine to access the serial console of another machine.

This project offers open source implementations for UNESCO/IFIP's Algol 68 (the Revised Report language). The project offers two implementations: Implementation 1 is Algol68G: a recent checkout hybrid compiler/interpreter by Marcel van der Veer, supporting arbitrary arithmetic, partial parametrisation, complex numbers, POSIX threads, GNU plotutils, GNU scientific library, curses, sound, TCP sockets, RegEx and PostgreSQL. Inplementation 2 is algol68toc, a port by Sian Mountbatten of the vintage Algol68RS (UK Defense Research Agency) compiler. The implementation emits C code.

libusbx is OBSOLETE and has been superseded by http://libusb.info

LinK+ IDE is a simple IDE for Linux Kernel Developers and Lovers. It is based on Eclipse IDE customized for Linux kernel programming. It reduces the development time and executes code in an elegant fashion. This IDE supports Linux kernel configuration, compilation & emulation, system call development and device driver development. LinK+ IDE includes various templates in the category of character, block and network device driver subsystems for device driver development. It includes various bus infrastructure templates and also provides Linux device driver code completion, code assistance & code navigation for developers.

Gammu is a cellular manager for mobile phones/modems. It contains libraries and functions for ringtones,logos,phonebook,SMS,etc. (used by external software), a command line version (with backup/restore) and SMS gateway (with MySQL and PostgreSQL supp

Parallel Events and Asynchronous tasKing Library. Originally combining multi-threading with an efficient I/O event model, it's now more a lightweight object-oriented framework for event-based applications.

Libinklevel is a library to check the ink level of ink jet printers connected via USB. Canon BJNP network printers are supported too. It works on Linux and FreeBSD.

Ink is a command line tool which displays the ink level of your printer. It makes use of libinklevel.

VTD-XML is the next generation XML parser/indexer/editor/slicer/assembler/xpath-engine that goes beyond DOM, SAX and PULL in performance, memory usage, and ease of use.

A Linux port of the OpenBSD/FreeBSD Cryptographic Framework (OCF). This port aims to bring full asynchronous HW/SW crypto acceleration to the Linux kernel, OpenSwan, OpenSSL and applications using DES, 3DES, AES, MD5, SHA, PublicKey, RNGs and more.

xfer9860 works with the fx-9860G (AKA Graph85) versions of Casio's graphing calculators. It allows you to transfer files to your calculator, and works on platforms where libusb is available - including Linux and Windows.

** Note: This projected has been halted. Please join #lg4l @ irc.freenode.net for more info.** A system of libraries and utilities to operate the Logitech G19 Gaming keyboard in linux and related operating systems.

POSIX API for Win2K-XP. Mainly implemented in the driver. Included: write-on-copy fork, threads, mutexes, spins, condvars, rwlocks, signals ... Signals/cancelation interrupt all waitable syscalls, NT syscalls are automaticaly restarted.

Serial line sniffer (slsnif). slsnif is a serial port logging utility. It listens to the specified serial port and logs all data going through this port in both directions.

sharing user-space memory. Includes a driver and an API as a set of functions. An application can allocate memory via malloc and share it with other independent applications via a device-driver. Functions to handle this in an easy way are provided.

FpgaC compiles a subset of the C language to net lists which can be imported into an FPGA vendors tool chains. C provides an excellent alternative to VHDL/Verilog for algorithmic expression of FPGA reconfigurable computing tasks. More info in wiki.

The openwince project collects free (open source) software tools, modules, applications, drivers, and so on for Windows CE platform developers. Some of the modules are usable outside Windows CE development environment and are platform independent.

Uart32 is a C++ wrapper around the win32 Serial Port API that allows blocking-mode access to the COM port. This library works great for accessing a UART serial port from a background worker thread. It features: a simple c++ class. (temporarily removed for maintainance. Use DLL API Instead) built in per access timeout on data receive. a C-API wrapper that is exportable to C# DLL import class

This is a simple command line tool to customize CP2103 USB to UART bridge controllers in home-grown hardware. VID, PID, product name string, serial number string, and release version of the device can be changed next to GPIO port modes.
