Creating an eclipse managed make project with MCU10 is easy: Starting the wizard with File > New > Bareboard Project and after a few clicks I have a project. I don’t need to worry about all the files in the project structure, until……..well, until I need to put the files into a VCS.
The Processor Expert USB CDC component posted in USB or not: CDC with Processor Expert has found many friends :-). A new version is available for download here with examples. It adds a bunch of new features and makes many things: simpler dependencies and setup, generation of an easily accessible cdc.inf and availability of error hooks. I have it running now with the TWR-MCF52259 and the DEMOJM (MCF51JM128 and S08JM60). Continue reading
This error message is something I see nearly every day in the Problems View:

No rule to make target
I had a PREN student showing up into my office. He wanted to choose a microcontroller for that project. One requirement put on the table was “it needs USB”. Well, I asked why USB is required. I was not surprised by the answer: “to use USB instead of RS-232”. Wow. So what he really wanted was USB CDC (Communication Device Class). Yep. Most notebooks today have no serial COM port (see “Processor Expert Configurations“). But because “USB is serial” does not mean “USB CDC is simple”. Nope. USB is not simple. But it can be with Processor Expert.
As outlined in Quickstart for Processor Expert in Eclipse, it is easy to create a new Processor Expert project. There are three shared files which are maintained by Processor Expert. At the same time I need to change them with my code. So how does this work, and how can I configure it to my needs?
Ok, you are probably new to Eclipse, and want to do the fun part: Creating an Eclipse Processor Expert project in CodeWarrior for MCU10.2. Cool! Here are some steps and tips to make it smooth from the beginning…
I have that wonderful project in MCU10.2 with Processor Expert using Embedded Components. It took me a while to carefully configure the settings, and now it works like a charm. I have another project and need the same components and settings in there. But how?
I have to make an application configuration decision: Using USB CDC or RS-232?
In the lab I use a Tower system which offers both RS-232 and USB connectivity. It uses a FSShell component to communicate with a terminal on the host. Typically this is using an RS-232 serial cable connected to the host. Well, the challenge is that today most notebooks do not have a serial port any more. But they have USB.
In my class a student wanted to run CodeWarrior MCU10.2 with Ubuntu 12.04 (Precise Pangolin) on a 64bit notebook. According to the Freescale Website, that version of Ubuntu is not supported. And indeed, if you install CodeWarrior and launch it, it does not work. The splash screen comes up, but then it aborts. Claiming in the workspace/.metadata/.log file that it cannot find the libswt-gtk-java and libxtst6 packages. Continue reading
I had a partner project meeting a couple of weeks ago. That project kicked off mid 2011 and came to an end with that meeting. That project started for me with a conflict and ended with a question: are engineers just pessimists? Continue reading
