aerl-official/aerl-c-framework

The AERL C++ Framework is a hardware abstraction library for Arduino and compatible boards such as the ESP32, aimed at people who are new to embedded systems and robotics. It wraps the standard Arduino functions in a simpler, more consistent style so beginners spend less time learning the details of the underlying platform and more time building things. Instead of calling different function names from different libraries, you use a single object called AERL with short, readable method names. Turning a pin on is AERL.on(pin). Turning it off is AERL.off(pin). Blinking an LED for a duration without freezing your code is AERL.glow(pin, ms). Reading a button state is AERL.read(pin, variable). Logging a value to the serial monitor is AERL.logline(data). Each function is documented in plain language in the README, explaining what it does in terms a beginner can follow. The framework also addresses a common problem in Arduino programming: doing something only once inside a loop that runs forever. AERL.run() returns true only the first time your code reaches it, and false every time after, giving you a clean way to run initialization code without moving it to setup(). A version with a count argument, AERL.run(n), lets you run something a set number of times. Communication protocols that embedded developers frequently need are also wrapped: UART for serial device-to-device communication, I2C for connecting multiple sensors on two shared wires, and SPI for high-speed components like displays. Each protocol has activate, send, and receive functions that follow the same naming pattern. The library is distributed as a single header file, AERL.h, which you drop into your project folder and include with one line. No package manager or build system is required beyond what Arduino IDE already provides. The project is currently in beta and explicitly flags two functions, sleep and wakeup, as likely to contain bugs. No license is stated in the repository. The project is developed by the Applied Electronics and Robotics Laboratory.
