[quote="eagletalontim"]That will take some time to learn about the cogs.  I tried to learn about them by reading the Propeller manual but still got lost :p  I did see a huge difference in the coding between the SX and the Propeller so hopefully I can pick up on the new language soon.  I have already ordered a Propeller Protoboard and the Prop Plug.  Now I just have to wait....[/quote]

Don't get wrapped around the axle (pun intended, as you do automotive projects) with the term "cog" -- it's a fancy term for processor.  In your dual-SX system you have to establish a communication link with wires and a protocol.  It's much easier going cog-to-cog: you simply define a section of hub RAM (main, 32K) that both cogs know about and can exchange information.  You could, for example, have a cog devoted to monitoring a sensor; it can write the sensor value to the hub were that value can be picked up by another cog that is maintaining a display.  

Yes, it takes a little time getting used to, but once you do you'll find that you can do advanced things more easily in the Propeller than in the SX (my opinion, not looking to start a war here).  I use the SX and Propeller every day and on a big SX-based animatronics control project I delivered a couple of weeks ago kept thinking, "Man, I wish this controller had Propeller on it."
