Disable my Code Generation

Posted on by

Processor Expert in MCU10 generates a lot of files for me. But sometimes I need to tweak things a bit. I change the generated sources to fit my needs, and then I want to prevent that my changes get overwritten by the next code generation.
First, I need to know which files are generated: the information in “Dissection of MCU10 Projects” helps me to identify them. But how can I prevent code generation for each component? Or for other generated files? Or how to completely disable code generation?

CDE: Inherited Component Base Name

Inheriting Processor Expert components with CDE and the Component Wizard is easy. But sometimes it is tricky and requires some tweaking. Components should be easily accessible (see CDE: Show Inherited Methods), and names should make sense. And here is a challenge: changing the name for inherited components:

Inherited Component with Inhr Base Name

Inherited Component with ‘Inhr’ Base Name

CDE: Show Inherited Methods

Using Processor Expert components makes my development faster and easier. And when I have a useful piece of software I want to distribute or use in another project, I transform it into a Processor Expert component. But recently I noticed a strange thing with my components: the inherited components did not show the methods and events?

Tracing FreeRTOS with a Hardware Probe

Posted on by

Using an RTOS is an excellent thing: it provides services and allows to scale my application. But it adds complexity. With many tasks, queues and semaphores it is hard to have an overview what is going on. To get visibility, Martin Bucher has developed in a bachelor diploma work the FreeRTOS Trace Probe.

Copy my Project

I’m using Subversion to keep track of changes in my eclipse MCU10 projects. That allows me to get back in time without the need to make copies of my project. But sometimes I do need to make a copy of my project: because I want to use a project as a base and then do something different with it. To make a copy of a project is simple, but requires some more steps if I’m using Target Tasks. Here is how I do this… Continue reading →

Dissection of MCU10 Projects

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.

USB CDC, reloaded

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 →

USB or not: CDC with Processor Expert

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.
