I used a LM3S8962 (or something like that) in a project last summer. Loved it. Especially the way the pins are set to be either I/O or a single peripheral function; too many times I've been unable to use all the features of a CPU because a single pin would be shared among multiple peripherals. -- newell N5TNL
