There has been many new releases these days: Freescale released Processor Expert Driver Suite 10.3, and Liviu Ionescu released new GNU ARM Eclipse Plugins with new and updated documentation. So time for me to show how this all comes together 🙂

It is now easier than ever before to use the GNU ARM Eclipse plugins and Processor Expert. There are still some manual steps, and this post is about all the details to get it working as smooth as possible.

For the next generation of INTRO Zumo robots I’m evaluating a new ‘brain’: more processing power, more FLASH, more RAM, more of everything 😉

DIY: Changing Processor Expert Components

Posted on by

I’m maintaining and hosting now more than 100 different Processor Expert components on GitHub. Instead to deal with CDE (Component Development Environment, that’s the SDK to create your own components), most users simply download and install the PEupd files. If you deal with normal source files, and if spot something you want (or need to change), then you can easily do this. But what if you want or need to change something in that code which comes with the PEupd file(s)?

Debugging the same Project Multiple Times in Parallel with Eclipse

I have I project which I want to debug on multiple boards the same time. So how can I download and debug the same application to multiple boards/processors, and debug them all the same time from within the same workspace and Eclipse IDE?

This is a typical scenario I have with my RNet stack: the same application runs on multiple boards, and I want to debug all the boards with the same project with the same Eclipse. For example to wireless sensor nodes with the RNet nRF24L01+ stack as in the picture below:

In Part 1 of this series I have covered the SD card on the Arduino Ethernet shield. In Part 2 I’m hooking up the board to the network and will be able to ping it 🙂

FRDM with Arduino Ethernet Shield R3, Part 1: SD Card

Sometimes it takes a very long time to realize a project. Adding the Arduino Ethernet Shield R3 to one of my Freescale FRDM boards is one of it: it took me a year until I have found a few days to work on using the Ethernet Shield with my FRDM-KL25Z.

I have not everything in place yet, so I decided to publish things in parts. So this is about part one: using the Micro SD Card on the Shield.

International Obfuscated C Code Contest Winners Announced

One of my favourite quotes about programming is this one:

“ Programming can be fun, so can cryptography; however they should not be combined. ” – Kreitzberg and Shneiderman

Well, there is truth behind this. But on contrary, there is a lot of fun with the combination of the two: the yearly IOCCC contest has posted the 2013 winners!

As in earlier years, it is amazing to see what can be done with creativity and a programming language like C ;-).
