The Kinetis ARM Cortex-M4(F) is a wonderful machine: a 32bit architecture, plenty of FLASH and RAM, an ideal play field. I love the Kinetis Tower boards, and even more the Freedom board which has an ARM Cortex-M0+ on it. I have a lot of projects on S08, S12 and ColdFire at the university, and they are all using a lot of Processor Expert components. Processor Expert is such a great productivity tool: having software in components allows easy software re-use. With Processor Expert abstracting from the hardware, I can easily port my applications to new boards and processors. Well, until Processor Expert changed for Kinetis :-(.
