Editor’s note: In this Design Idea (DI), contributor Bonicatto designs a digital filter system (DFS). This is a benchtop filtering system that can apply various filter types to an incoming signal. The ...

MicroQuickJS is a new project from Fabrice Bellard, who has created many other open-source projects, including QEMU, FFmpeg, ...

FastMap replaces the Arduino map() function which does integer mapping. The result of integer mapping is that the (internal) division truncates and looses precision. Another problem possible problem ...

Nothing big, just my own implementation of an associative array - also known as Map or HashMap (when you're coming from Java) for all kind of Arduino projects. I wrote it to use in my Arduino projects ...
