WiFly - What kind of processor if any?

Hi all,

This is my first post here, so please excuse me if it seems like a dumb question. I am attempting to come up with the basic overview of a stand alone WiFi network and I planned to use a WiFly unit, as it seems like the most affordable and useful for my purpose. My system will have a separate FPGA board with USB interface for a dedicated network application. I need to run some extra software for this, so the system needs a processor of some sort.

I had hoped I might be able to use the WiFly device to run the extra process too, but I can't seem to find any info on what kind of processor it has (if any). My guess is it has an AVR tucked in there somewhere.

I assumed the WiFly has some processor or another, as the specifications say it's running the ECOS - OS (as well as a TCP/IP stack, telnet, client DNS etc... etc.). I read somewhere that this was designed to only run one process. Does anybody know what processor the WiFly uses and whether it's feasible to run extra software. Otherwise I have to look at some other embedded system to include I suppose.

Thanks for any help in advance.

I can't help you with what processor is on board that wifi module. But in terms of price (ignoring the form factor for the moment), it seems a wifi router would easily be half price of the breakout board, and include all the supporting hardware.

Several open source projects are available like OpenWRT , DDWRT, and others, which allow you to add packages to a small footprint linux OS. Lots of routers are supported, with some models having a couple of USB ports, and extra ROM/RAM which could be handy.

I picked up a popular model, the Linksys WRT54GL, at the thrift store. I'm a complete newb at networking and linux, so this is going to be a slow process for me. Managed to brick it, so it now has a JTAG and the RS232 port hooked up, with the ultimate goal of talking to a microcontroller over the second UART port. USB also seems possible on the WRT54GL, and will probably bring those out too.
