In the 2006 FTF I asked some tips abotu wi-fi x ColdGire V2.
At this exact mokent I´m drawing a 5235 design, iwch must have wi-fi support.(I don´t use OS)
Considering the context I approached, I understood the following:
a) I don´t need government approvals if I use a already done wi-fi card, instead of single chipsets
b) The support from the chipsets producers are very far from the confortable, or almost no support
c) There are CF(Compact Flash) cards available, but they aren´t so popular and cheap as PCMCIA ones.
d) I can drive PCMCIA popular cards trough a CF bus, wich is a frendly task for embedded devices and very friendly to ordinary paralel buses
e) Although using CF bus to drive a PCMCIA card, it is interesting to chose devices wich have Realtek / Intersil or Conexant chipsets.They are usually more friendly ....
f) For "simple / basics comands" with these PCMCIA cards, I will probaly not need to rewrite the driver.It probaly will be necessary when using more sophisticated resource from them.
g) By my researchings, several 8 bits microcontroller designs has been bult using the approach above..so certainly it can be done with a ColdFire emgine...
h) There is avery nice book about wi-fi for embededded devices, from Fredy Eady, wich approches a wi-fi based web server for 8 bits microcontrollers using CF bus.He is an Circuit Cellar magazine (USA) writer..He based on a 51´s core
Well, tis my undesrstanding up to now, maybe some poinbts are not so right, but it is I got..
I hope it helps you ...
