I have recently been asked several times about the code details for my Arduino RSS Reader. I have been freely handing this out, so it is now posted here for everybody to download: Download RSS Reader Sketch This zip archive contains the Arduino sketch and a few custom libraries (including the RSS parser). The amount [...]

A Better Real-time Library for Arduino
For my project I required a simple timer library for the Arduino development environment, something with a simple-but-powerful interface to schedule tasks to complete in the future or at regular intervals. There doesn’t really seem to be anything suitable online – a host of over-complicated APIs that use several classes, structs and rely heavily on [...]
Reading RSS on the AVR
Last February, I saw an RSS Reader implemented on an AVR ATmega8, which seemed impressive but was, in reality, just a serial-controlled LCD terminal. The general consensus was that it’d be cool if this were done without the requirement for the PC – this was the topic of my third-year project at university. My Embedded [...]
Another Step Forward
I now have all the component parts in place for my Embedded RSS reader, Ethernet, TCP and the liquid crystal display (who knew the pin-out was backwards?). The software is almost complete too, just a morning of integration and a little testing then there should be something to post here in the form of a [...]
Downloading RSS to the AVR
I have finally managed to fix a nasty little bug with my AVR-powered RSS reader (more details coming here shortly). Basically, it would get half-way through downloading the RSS document, pause for a second and the AVR would restart itself. I thought it was an issue with the network connection, but trying to diagnose over [...]

AVR Development on the Arduino
I have just started using an Arduino for my project. I hadn’t considered it as a platform before, but I am starting to love it for rapid development. It is so usable – no loose wiring to connect up programmers or power supplies – it’s all integrated into a single unit. I very nearly have [...]

Pointers on the Atmel AVR
I have just resolved a rather weird bug in a 3rd party library for the Atmel AVR. Compiling under OS X the code runs perfectly, but on the AVR it runs like a dog. The secret is, apparently, in the heavy use of C pointers and pointer arithmetic to manage complex data structures within the [...]
Debugging in OpenGL
The computer scientist, Brian Wilson Kernighan once said: Debugging is twice as hard as writing the code in the first place. Therefore, if you write the code as cleverly as possible, you are, by definition, not smart enough to debug it. This is well enough, but trying to do some graphics programming, using the OpenGL, [...]
