Project Brainstorming
So, what do you all think about a processor choice? There are several options for ARM Processors. The Cortex-M series seems to be at the level at which we need our processor to be at, though I will need to read more on it and the other processors.

We will use RTL 8181 SOC chip with two integrated Ethernet MACs and a WLAN 802.11b controller embedded onto a single chip.
This is Linux for This chip rtl8181.sourceforge.net/

I think we are leaning more toward connecting an ARM processor to a separate wifi module. We will be meeting on 9/23 to discuss this further. As we talked about in the teleconference, our teams don't have to have the same processors as long as we agree on the protocols. We will being doing some more research on the RTL8181, however.

Hi everyone,
This could be one additional option for a processor http://www.ti.com/lsds/ti/microcontroller/arm_stellaris/overview.page?DCMP=Luminary&HQS=Other+OT+stellaris
It's a TI microcontroller with an ARM Cortex M3 processor. I think that we may have looked at this during our meeting on Friday. It has embedded ethernet which would be nice. This is a development board for it as well - http://www.ti.com/tool/ek-lm3s6965
Also, we should probably agree on what the car should be able to do:
- Are we going to have both of the cars each host different web pages or will there be one central web page?
- video camera on board?
- other things such as sensors to check for imminent collisions?
-anything else that I didn't think of...

Scott, that's what pretty much what I was thinking - the 9000 series has 8 PWM outputs, plenty for our needs (
).
