Embedded Components

Welcome to the exciting world of Processor Expert Embedded Components!

This site contains components using the Processor Expert Embedded Components technology, as used in CodeWarrior for Microcontrollers 10.x (in short: CW MCU10.x). I'm using MCU10.3, but in general the components are backwards compatible.

The initial set of components have been created in a research project at the Lucerne University of Applied Sciences and Arts where I'm teaching Embedded Systems Programming. The Embedded Components are used in our research projects, in many student projects and of course as well in my own projects :-).

Important Information

Starting January 1st 2013, the latest and greatest versions of components and examples are hosted on GitHub.

More Information

I'm maintaining my own blog at http://mcuoneclipse.com. There is as well a book coming out soon, see this link. And everything is hosted on GitHub too.

How to Install Embedded Components

Download the Embedded Components to your harddisk (Save as...). Use the menu 'Processor Expert > Import Package':

Import Component

Then browse to your downloaded component (you can import multiple components in a single step).

After you have imported a component(s), use the 'Refresh' context menu in the 'Components Library' view or restart MCU10.

If you have changed/updated a component, it is enough to close the project and re-open it again (select project, menu 'Project > Close Project' and then 'Project > Open Project'. This ensures that the latest and greatest Embedded Component driver is loaded.

Note: MCU10.2 has the 'Component Wizard' menu removed, as MCU10.2 contains the CDE (Component Development Environment) inside eclipse. If you still need to use the 'classic' Component Wizard, it is still availble in <Installation>MCU\ProcessorExpert\BeanWizard.exe.

Example Projects

Example Projects and Instructions how to use the example projects can be found here.
