Cycle precise delay loop in C++

Implementing a cycle-precise delay loop in C++ for embedded system

In a recent work on Marlin's printer firmware, I found a pending pull request about waiting for precise, ideally nanosecond timed, delays.

While it looked like easy at first, the implementation proved tricky. This post explains...

eMQTT5 technical review

Technical review for minimization of resources in eMQTT5

eMQTT5 is a MQTT v5.0 client that's targetting low resource usage for embedded system.

In order to achieve this goal, we've used many tricks and technics that we'll present below.

No heap allocation
