TFT_eSPI
Arduino and PlatformIO IDE compatible TFT library
An Arduino IDE compatible graphics and fonts library for 32-bit processors. The library is targeted at 32-bit processors, it has been performance-optimized for STM32, ESP8266 and ESP32 types. The library can be loaded using the Arduino IDE's Library Manager. Direct Memory Access (DMA) can be used with the ESP32, RP2040, and STM32 processors to improve rendering performance. "Four wire" SPI and 8 bit parallel interfaces are supported. Due to the lack of GPIO pins, the 8-bit parallel interface is NOT supported on the ESP8266. 8 bit parallel interface TFTs (e.g. UNO format mcufriend shields) can use with the STM32 Nucleo 64/144 range or the UNO format ESP32. ILI9341 and ST7796 SPI-based displays are recommended as starting points for experimenting with this library. The library supports some TFT displays designed for the Raspberry Pi (RPi) that are based on a ILI9486 or ST7796 driver chip with a 480 x 320-pixel screen. -

libusbmuxd
A client library to multiplex connections from and to iOS devices
A client library for applications to handle usbmux protocol connections with iOS devices. This project is a client library to multiplex connections from and to iOS devices alongside command-line utilities. It is primarily used by applications that use the libimobiledevice library to communicate with services running on iOS devices. The library does not establish a direct connection with a device but requires connecting to a socket provided by the usbmuxd daemon. The libimobiledevice project provides an open-source reimplementation of the usbmuxd daemon to use on Linux or as an alternative to communicate with iOS devices without the need to install iTunes. The architecture of the library and dependencies has been designed with an OOP approach in mind. Thus bindings for other programming languages are easier to create and allow an OOP based API. Linux enthusiasts were not amused about great but incompatible hardware like the iPhone 2G. -

base64 RFC1113 Vanilla ANSI-C Code for a portable stand-alone file encode/decode utility. In 2001, I asked people to 'Help me break it!' Since then, 10+years later, the code remains unbroken and is in wide production use world-wide. It has been ported to all major architectures and been used as a template for ports to different computer and human languages. This is very mature and stable code. Although this comes from a project that was constrained by export controls and is used in secure systems, it is not security code per-se. I have therefore altered the 'Export Controls' category.

CGL
CGL (C Game Library) is a multipurpose library
cgl is a compact, header-only C graphics library for 2D drawing operations using software rendering. Designed for simplicity and portability, cgl allows rendering of primitives such as lines, circles, triangles, and text to an in-memory framebuffer, which can then be displayed with any platform-dependent backend. It’s ideal for building custom engines, retro-style games, GUIs, or educational demos where GPU acceleration is not required. Its small footprint and lack of external dependencies make it easy to embed in any C project. -

ESP8266Audio
Arduino library to play MOD, WAV, FLAC, MIDI, RTTTL, MP3
Arduino library for parsing and decoding MOD, WAV, MP3, FLAC, MIDI, AAC, and RTTL files and playing them on an I2S DAC or even using a software-simulated delta-sigma DAC with dynamic 32x-128x oversampling. ESP8266 is fully supported and most mature, but ESP32 is also mostly there with built-in DAC as well as external ones. For real-time, autonomous speech synthesis, check out ESP8266SAM, a library that uses this one and a port of an ancient format-based synthesis program to allow your ESP8266 to talk with low memory and no network required. All this code is released under the GPL, and all of it is to be used at your own risk. If you find any bugs, please let me know via the GitHub issue tracker or drop me an email. The MOD and MP3 routines were taken from StellaPlayer and libMAD respectively. The software I2S delta-sigma 32x oversampling DAC was my own creation and sounds quite good if I do say so myself. -

Efawin
Interact with AWS Elastic Fabric Adapter on Windows
Efawin library helps applications on Windows to interact with Elastic Fabric Adapter hardware on AWS EC2. It provides the necessary functionality through an interface that is very close to infiniband verbs interface. At this time, this library is scoped to support the libfabric efa provider that is part of the Open Fabrics Interfaces (OFI). See the OFI website for more information on libfabric. Any other use of the library is not tested or supported. This library provides the necessary functionality to create and manipulate the queues associated with AWS Elastic Fabric Adapter. Majority of the library's functionality comes from rdmacore's efa provider. To allow compilation of the library on Windows, some helper/compat files have been copied from the OFI's libfabric. The Efa driver interaction files have been copied from a AWS fork of libfabric. In addition to these, the Infiniband header files from OpenIB are used to provide an interface to the library. -
