Have you ever thought about designing an oscilloscope? What about a WiFi scope? In this series of articles I show how to design a very simple low-frequency WiFi “oscilloscope” using an Onion Omega2+ and a STM32 microcontroller.
In this article I show a simple C library I wrote for the STM32 to help debouncing keys. It is completely non-blocking and also includes a nice auto-repeat feature with progressive speed! I wrote this library to complete an assignment
