When Microcontrollers Struggle with Math: Building Herald

Why I Built Herald &#xA; Microcontrollers are great, until you ask them to do math. &#xA; Try throwing trigonometry or signal processing at a small MCU and things slow down very quickly. This is especially true for cheaper or simpler chips that either do not have a floating point unit or rely on relatively expensive hardware support. Even when FPUs are available, they are not always the best…
