rt-thread - RT-Thread is an open source IoT operating system from China.

•    C

---

RT-Thread is an open source IoT operating system from China, which has strong scalability: from a tiny kernel running on a tiny core, for example ARM Cortex-M0, or Cortex-M3/4/7, to a rich feature system running on MIPS32, ARM Cortex-A8, ARM Cortex-A9 DualCore etc. The device driver is more like a driver framework, UART, IIC, SPI, SDIO, USB device/host, EMAC, MTD NAND etc. The developer can easily add low level driver and board configuration, then combined with the upper framework, he/she can use lots of features.

tinyformat - Minimal, type safe printf replacement library for C++

•    C++

---

All user facing functions are defined in the namespace tinyformat. A namespace alias tfm is provided to encourage brevity, but can easily be disabled if desired. Three main interface functions are available: an iostreams-based format(), a string-based format() and a printf() replacement. These functions can be thought of as C++ replacements for C's fprintf(), sprintf() and printf() functions respectively. All the interface functions can take an unlimited number of input arguments if compiled with C++11 variadic templates support. In C++98 mode, the number of arguments must be limited to some fixed upper bound which is currently 16 as of version 1.3. Supporting more arguments is quite easy using the in-source code generator based on cog.py - see the source for details.

mbed - Tool for Rapid Prototyping with Microcontrollers

•    C

---

The mbed Software Development Kit (SDK) is a C/C++ microcontroller software to write code for ARM microcontrollers. It provides enough hardware abstraction to be intuitive and concise, but powerful enough to build complex projects. It includes all the base level startup code, C runtime and library pre-integrated and tested for the target microcontrollers, and high-level MCU peripheral APIs that allow you to drive the peripherals of the microcontrollers without going near a datasheet.

zinc - The bare metal stack for rust

•    Rust

---

Zinc is an experimental attempt to write an ARM stack that would be similar to CMSIS or mbed in capabilities but would show rust's best safety features applied to embedded development. Zinc is mostly assembly-free and completely C-free at the moment. One of the goals of zinc is to figure out, how much of the usual RTOS stack is it possible to write in rust in a safe manner, while keeping the resource usage profile low enough (comparable to C/C++ code).

printbf - Brainfuck interpreter inside printf

•    Brainfuck

---

Generic POSIX printf itself can be Turing complete as shown in Control-Flow Bending. Here we take printf-oriented programming one step further and preset a brainfuck interpreter inside a single printf statement. An attacker can control a printf statement through a format string vulnerability (where an attacker-controlled string is used as first parameter to a printf-like statement) or if the attacker can control the first argument to a printf statement through, e.g., a generic memory corruption. See the disclaimer below for practical in the wild considerations.

ferret - Ferret is a free software lisp implementation for real time embedded control systems.

•    Makefile

---

Ferret is a free software lisp implementation designed to be used in real time embedded control systems. Ferret lisp compiles down to self contained C++11. Generated code is portable between any Operating System and/or Microcontroller that supports a C++11 compliant compiler. It has been verified to run on architectures ranging from embedded systems with as little as 2KB of RAM to general purpose computers running Linux/Mac OS X/Windows. A program that sums the first 5 positive numbers.

tock - A secure embedded operating system for Cortex-M based microcontrollers

•    Rust

---

Tock is an embedded operating system designed for running multiple concurrent, mutually distrustful applications on Cortex-M based embedded platforms. Tock's design centers around protection, both from potentially malicious applications and from device drivers. Tock uses two mechanisms to protect different components of the operating system. First, the kernel and device drivers are written in Rust, a systems programming language that provides compile-time memory safety, type safety and strict aliasing. Tock uses Rust to protect the kernel (e.g. the scheduler and hardware abstraction layer) from platform specific device drivers as well as isolate device drivers from each other. Second, Tock uses memory protection units to isolate applications from each other and the kernel. Tock is documented in the doc folder. Read through the guides there to learn about the overview and design of Tock, its implementation, and much more.
