A simple WiFi scope (Part 2 – Server and Client)

A simple WiFi scope (Part 2 – Server and Client)

In my previous article I showed how we designed the STM32 firmware for our simple WiFi scope. Now it is time to explore the server code running on the Onion Omega 2+ and the graphic client!

A simple WiFi scope (Part 1 – STM32 firmware)

Trigerring with 4x oversampling

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.

Getting started with the Onion Omega 2+ and Node.js

In this article I present the Onion Omega 2+ and show you how to get started with it using Node.js. Onion Omega2+ is a stamp-sized Linux computer (42.9 x 26.4mm) featuring a 580MHz MediaTek MT7688 processor (MIPS24KEc core), 128Mb DDR2
