First NXP Kinetis SDK Release: SDK V2.0 with Online On-Demand Package Builder

Posted on by

There are plenty of different software packages available for microcontroller these days from all the silicon vendors. Finding a good software package is one challenge, getting what I really need is another one. Freescale is now part of NXP since December 2015, so this is probably the first release of the former Freescale part now as NXP: The NXP Kinetis SDK Version 2.0.

It comes with an interesting distribution way: instead of downloading huge packages with all-and-everything in it, I can build it ‘on demand’ online and get what I need, on demand from a web-based front end:

Controlling NXP Freedom Board RGB LED with openHAB and Raspberry Pi

In “Blinky LED with openHAB on Raspberry Pi” I have used openHAB on a Raspberry Pi to control an LED attached to the Pi, and in “Controlling NXP Freedom Board RGB LED with openHAB and Raspberry Pi” I have explored how to connect a NXP Freedom Board over USB CDC to the Raspberry Pi. In this article I’m going to combine both: to control the LED on a NXP Freedom board remotely with openHAB on the Raspberry Pi.

Debug Multiple Boards with GDB at the Same Time

Many times it is very useful to debug multiple boards at the same time. For example if I’m debugging a communication stack between two boards: that way I can debug the protocol on both sides. Eclipse is a great framework which allows that. This post shows how to debug multiple boards (e.g. the NXP Freedom boards) in parallel from the same Eclipse IDE using GDB and the Segger J-Link:

USB CDC with the Raspberry Pi

For my home automation project with openHAB I want to attach Freescale (now NXP) FRDM (Freedom) boards so they can take care about the realtime aspects and to act as gateways to my other systems. One way is to use USB CDC (Serial over USB) as communication channel. USB has the advantage that it powers the board, plus I can attach multiple devices: up to four on the Raspberry Pi 2 and even more with using a USB hub. In a standard configuration with a USB WiFi and a USB HID (mouse plus keyboard) dongle I still can attach two Freescale (ahem, NXP) Freedom boards to the Raspberry Pi:

New Gadget to Explore: Freescale FRDM-K82F Board

It’s not Christmas yet, but: For a research project I’m currently evaluating a new microcontroller where I need a bit more leg room. Right on time I saw that there is a new board available which caught my interest: The Freescale FRDM-K82F :-). Without thinking too much about it, I have ordered that board from Mouser Thursday last week and I had it in my hand today 🙂 Time to put up a quick post about it:

The bad news: my ESC (see “Kinetis Drone: Graupner ESC S3055 Failure“) for my Kinetis drone is still not repaired :-(. Anyway, I have plenty of other things to make for my drone project. One is to work on the remote controller:
