📘 Operating Systems Notes

Short article with key moments to remember about operating systems.

Here are some rough notes author put together as part of revision for a university course. They are heavily based on the course lecture notes by Kevin Elphinstone and Leonid Ryzhyk.

All diagrams are sourced from those lecture notes, some of which are in turn from the text book, A. Tannenbaum, Modern Operating Systems.

📥 Building a Linux system for the STM32MP1

Series of articles that describes how to build an embedded Linux device based on the STM32MP1 platform, using the Buildroot build system.

Buildroot is a set of Makefiles and script that automates the process of download the source code of the different software components, extract them, configure them, build them and install them.

The hardware platform used in these articles is the STM32MP157-DK2.

🎬 What Actually is Embedded C/C++? Is it different from C/C++?

💻 uLisp - Lisp for microcontrollers

uLisp is a version of the Lisp programming language specifically designed to run on microcontrollers with a limited amount of RAM, from the Arduino Uno based on the ATmega328 up to the Teensy 4.0/4.1. You can use exactly the same uLisp program, irrespective of the platform.

Because uLisp is an interpreter you can type commands in, and see the effect immediately, without having to compile and upload your program. This makes it an ideal environment for learning to program, or for setting up simple electronic devices.

Lisp is also an ideal language for learning about fundamental programming concepts. It incorporates string handling, list processing, and garbage collection, and so is also an excellent language for expressing complex ideas, such as teaching a robot to solve mazes or finding the shortest route on a map.
