FRDM with Arduino Ethernet Shield R3, Part 3: Embedded Web Server

Posted on by

This is Part 3 of an ongoing tutorial to use the Arduino Ethernet Shield R3 with a Freescale FRDM-KL25Z board (or any other board you like).

In Part 1 I worked on the SD card, in Part 2 I have added basic network connection. Now time to run a web server with my FRDM-KL25Z :-). With this, I can get access to my board through the network, and the board will host a web page where I can do pretty much everything: showing status, or adding functions to turn on things like an LED 🙂

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 🙂
