Wireless Networking with 16f877?

Started by Kevin Van Winkle June 23, 2004

I thought I'd put this query out there in the hopes of not having to
reinvent the wheel.

I'd like to use a 16f877 (Or similar) to talk via 802.11b/g.

I know of the 8/16 bits kludges of regular NICS to this chip, but was
thinking of wireless if anyonw had done it. I'm considering all
possibilities (USB NIC, PCCARD(Cardbus/pcmcia) or PCI) All have issues.

The USB would be the simplist interface, but I fear it is software intensive
and would require quite a bit of backwards engineering to get it to talk in
this application. Much like trying to deal with a "Software" modem I would
think.

The PCCARD style is attractive, but I don't know much about it, and creating
a bus for it or a PCI card seems kind of tough given the limitations of a
PIC micro.

I did see DIGI had some modules, but at $108 each, maybe out of range for a
project that could have commercial implications.

So, anyone have PICs making a living on their wireless networks without some
intermediate interface really doing the work? (IE, pic talks to pc that
talks via 802.11)

How about hanging an ethernet interface on the PIC, and then using a
standard WiFi interface?

You may want to look at this!
http://www.lantronix.com/products/eds/wiport/ Serial interface to a 802.11b
tranceiver. I do not know of the price. They also have a dev. kit

Price from my local distributor some 110 Euro, about $135. Pretty expensive
IMHO considering you can buy WiFi cards for $20 or less...agreed these come
with twists, but boy, they make you pay for them. I think that their Xport
is good value for money, however.

Regards,

Mike
