UART Based Networking for Microcontrollers

This article describes a simple networking system that supports multiple slave devices connected to a single serial port on the host system. The microcontroller side only requires a UART and can be implemented with a minimal amount of code. Background Almost two years ago I designed and built a small…

The Benchtool - Where Now?

The competition I originally started working on the Bench Testing Tool is now over (see this post for details) but the project is far from complete and I would like to finish it off - mainly so I can use it myself but also because a number of people have…

Brisbane Makes Makercamp

Yesterday was the Brisbane Makes Makercamp at Hackerspace Brisbane and the culmination of the Make Anything competition I had entered. It was a very full day - the number of interesting people and interesting projects was incredible. The chance to talk with such a large group of like minded people…

Benchtool Sampling Firmware

The past weeks worth of work on the Benchtool Project has been focused on the firmware for the sampling module. I've used a Stellaris Launchpad for this part of the project. This update is just a quick rundown on how things have progressed so far. Developing for the Launchpad I've…

Benchtool UI Demo

Here is a sample of the Benchtool UI: This is a simulated view, I'm using my QuickUI library with the VNC driver and the Java window manager library. Inputs are being simulated - it's not talking to any real hardware at this stage. It's not exactly the prettiest UI around…

A Quick Update on the Benchtester

This is a quick (and long overdue) update on the status of the Benchtester project that I'm building as part of the Brisbane Makes competition. I've spent most of my available time working on a simple UI for the device. This has grown a little bit larger than I originally…

Bench Testing Tool

This project is an intelligent, software driven bench testing tool that is a combination of a multi-channel Digital Voltmeter (DVM), a Digital Ammeter and can also provide a number of independent voltage reference sources. As well as being a useful addition to my workbench this project is my entry in…
