Hi!
I'm Elkin Granados from Thesis Electronic Engineering. I'm a Electronic Engineer from Colombia, I have been worked the last 3 years in design and development of electronic devices. In those years I have been working with Freescale microcontrollers, I know several families as the HCS08, Coldfire and the newest Kinetis.
On this moment I'm working with the Freedom board K64F, this board have a microcontroller that have the ethernet peripheral embedded, currently I'm developing boards with this communication.
The Kinetis family have and IDE called Kinetis Design Studio, which is completely free and don't have code size restrictions, so you won't have any kind of issues with this, you only download it, load the code, compile and burn. I'm using it right now and have some advantages that allows a faster development.
I keep looking forward for your reply! Have a nice day!
