Weekends are great: time to do some great stuff...
I have finished a shell (command line interface) for the Freescale Kinetis Cortex-M0+ Freedom board (http://www.element14.com/community/community/knode/dev_platforms_kits/element14_dev_kits/kinetis_kl2_freedom_board). It is running FreeRTOS, changes the board RGB LED with from individual tasks, and imlements a command line shell, including a real-time clock interface.
The UART traffic is routed through the OpenSDA Debug connection to the host computer (creating a virtual COM port).
See A Shell for the Freedom KL25Z Board for more details.
Have Freedom :-)
