Does anyone know of any 802.11 ‘devices’ (i understand it may be more than just a single chip) that I can reasonably buy to interface with a uC? I’m planning on using the [PIC18F97J60 (initially using the IPv4 stack that they distribute for free but eventually developing an IPv6 stack) to create wireless sensors and controllers. Any help would be appreciated](http://www.microchip.com/stellent/idcplg?IdcService=SS_GET_PAGE&nodeId=1335&dDocName=en026439)
Would something like this work?
I don’t think I could interface to a PCI device using a PIC. I was thinking of something more along the lines of http://www.multitech.com/DOCUMENTS/Coll … 002080.pdf but more ‘dump’ (and not $80 lol) I can handle all the packet generation and stuff (using the ip stack) but I need some way to send it out
Edit:
Actually with a cursory glance at some more stuff on digikey i found this, http://www.csr.com/media/pdf/UPort-pb-0 … 0Brief.pdf (http://search.digikey.com/scripts/DkSea … -IC-ECT-ND) which is only $15 and seems to be what I want.
WiFi SDIO cards for PDAs are what some brave souls have used. Very, very difficult though. That chip referenced above is likely so encumbered. Much of the MAC is not in that chip, nor IP and all the rest. Some try to adapt Linux drivers (megabytes of source code).
Easy: Buy a LANTRONIX WiPort or lower cost Matchport module. Connect its 3.3V serial port to the serial port on your microprocessor. Configure the WiPort to be either a transparent serial cable replacement, where a virtual COM port on a PC connects to the serial port on your microprocessor (freeware with WiPort), or use WiPort in the UDP or TCP connection mode, where your own special software runs on a PC.
There are two versions of the WiPort: one can be custom programmed, and another lower cost one cannot. Both have a web browser interface to
configure the many settings.

I have used WiPort. It’ll take you an hour or two to get it working with this serial port scheme.
THere used to be 2 or so other competitors.
I wish Sparkfun would carry these. Digikey and Mouser sell these, but there are minimums, with these big guys.
wow that is WAAAY to expensive. I would much rather spend more time creating/programming this thing then spending $115 per. Especially since I plan on creating many of these.
there is this too.
