At FTF 2014, Freescale made the announcement that CodeWarrior won’t support all the new ARM Kinetis devices coming out in the future: they will be supported with the free-of-charge Kinetis Design Studio (KDS) instead. As for myself, this is a big shift from a well established CodeWarrior toolchain to something new. A question which came up recently several times in the forums and in other posts is: how do CodeWarrior and KDS compare with each other?
Sometimes I have a good idea how to extend one of my Processor Expert components with an extra feature, but then I step back because why implementing more than I need at the moment? Until another user of the component simply asks for the same thing, and here we go: if one or more can take advantage of a feature, that’s definitely a strong argument to add it :-). This happened with the RingBuffer Processor Expert component I’m using in many projects. And a reader of this blog asked to add some extra event methods: when an item is added or removed to the buffer.
I have to admit: I’m not a vegetarian. I love BBQ, and no offense to vegetarians! Today is perfect day for another BBQ session, and this time I plan to enhance it with electronics. No, not eating electronics, but doing BBQ with a little DIY electronic helper. There are different ways to cook meat on an open fire pit, and each region of the world has its own way to do it. Traditionally, in my area we are ‘grilling’ the meat: high temperature, for a few minutes, done! I like that ‘fast food way’ too, but there is an even better version: Slow food smoking!
I’m gifted that I had the opportunity to experience the Texas BBQ culture: slowly cooking the meat, at low temperature, and ‘smoking’ it: Cooking the meat around 80°C prevents that it gets dry (because the water does not vaporize, see this article on Wikipedia). There are different ways how to do this, but I love the way how it is done at the Salt Lick in Austin/TX with an open fire pit:
The semester started last week. Ideally I wanted to have the boards for the new S robot (see “Zumo Robot with WiFi and GPS“) ready in the first week. But our manufacturer was not able to get the four-layer boards with parts populated and delivered in that time frame. Until the new boards arrive, we have anyway plenty of things to cover. One thing is to build a prototype shield to host several distance sensors, nRF24L01+ and Bluetooth transceiver:
This Tip sounds very basic, but still: I get asked about this about once a week. So it must be something non-obvious in Eclipse then ;-): how to add existing files to an Eclipse project. As with many things in Eclipse, there is not a single way to do something. There are two basic ways to do this:
- Drag & Drop
- Copy & Paste
The first is the ‘official’ way in Eclipse, the other two are much faster and easier :-).
To import one or multiple files, select the folder/project where I want to add the files, then use the menu File > Import:
Eclipse has a great user interface (UI). But what if I want to do things from the command line, without the GUI? For example to build one or more projects in the workspace without using the Eclipse UI? With this, I can do automated check-outs and do automated builds.
In “Semihosting with Kinetis Design Studio” I used printf() to exchange text and data between the target board and the host using the debug connection. Kinetis Design Studio (KDS) has that semihosting baked into its libraries. What about if using the GNU ARM Embedded (launchpad) tools and libraries (see “Switching ARM GNU Tool Chain and Libraries in Kinetis Design Studio“)? Actually it requires two more steps, but is very easy too.
P&E has just released a new version of their Eclipse plugins for the set of GNU ARM Eclipse debug plugins. The GNU ARM Eclipse plugins from Liviu support OpenOCD and Segger J-link, so with this update or extension it adds P&E support to it. With this, I can use the P&E debug devices (P&E Multilink, Tracelink) or as well the Freescale OpenSDA with it.
On my way to the airport to catch an early morning flight. Leaving home and waiting for my train to arrive, and maybe I’m already spotting my plane there?
One really cool thing with Processor Expert is: it does not only generate the source code for me, it generates as well documentation :-). I’m a believer of the ‘single source’ approach: if I have to document a software project, then the software itself shall be the source of the documentation. And for this I love Doxygen: see “5 Best Eclipse Plugins: #1 (Eclox with Doxygen, Graphviz and Mscgen)“. Doxygen is a compiler which compiles my source files, and instead of object files it creates documentation files for me :-).
