Well, life got in the way of my Renesas RX Design Contest entry. I still have ambitions to use the RX chip in a real project, but kids and work and prototyping issues prevented me from finishing my project before the contest deadline. I think the RX600 series is a capable product line: 100MHz operation, a hardware floating point unit, and an external memory bus are key features in my project and the RX gives them to me.
I haven't yet checked out the contest entries, although I heard only 30 projects were entered. That's a shame; I feel kinda bad for taking this hardware that came with the contest signup and not giving back a project. So part of the reason I'm commited to finishing my project is to assuage my guilt.
