Book: Practical UML Statecharts in C/C++, 2nd Ed

The second edition of the “Practical Statecharts” book by Quantum Leaps’ Miro Samek bridges the gap between high-level abstract concepts of the Unified Modeling Language (UML) and the actual programming aspects of modern finite state machines (UML statecharts). The book describes a lightweight, open source, event-driven real-time embedded framework (RTEF) called QP™ that enables a straightforward implementation of UML statecharts and concurrent event-driven applications in C or C++. https://www.state-machine.com/psicc2...

Building a Ground station for LoRa Satellites

The arrival of small satellites that used LoRa for telemetry data has meant that less technically qualified persons, with a very low budget, can receive their signals. Thanks to TinyGS, there is now an open network of distributed ground stations, and more stations can be built to increase their coverage. The project presented here is a reasonably robust, dust-resistant and waterproof implementation of TinyGS ground station, using commercial off-the-shelf components. Ideal for outdoor usage. https://hackernoon.com/building-a-ground-station-for-lora-satellites...
