Check out the new Component Development Environment, available here: http://www.freescale.com/webapp/sps/site/prod_summary.jsp?code=PE_CDE&tid=PEH
There is a free community edition, so it costs you nothing (unless you want to sell components). Even better, if you have CodeWarrior installed, it’s already integrated. (File->New->Embedded Component). Or you can download an Eclipse plugin and use it independently.
You can create your own Processor Expert components for fun and frolic. You can get a lot of example components and information at http://www.steinerberg.com/EmbeddedComponents/
