[Coco] Someone's next hardware project: WiFi

[Salvador Garcia]

This Wifi module is one of many.

My question (more to myself and the original poster, plus any one else that wishes to discuss it) is the following: What is the objective of getting a Wifi module to work with the CoCo?

I don't believe it is that difficult to interface the module with the computer, but connecting the CoCo to a Wifi network is one thing. It is an entirely different thing to have it communicate with other devices on the network. A protocol needs to be used (most likely TCP/IP) and a driver developed, plus the application that will make use of it.

There can be legitimate uses for a WiFi network adapter for the CoCo, and any reason just because it is there, but if, for example, the objective is to eliminate the cable then perhaps a wireless serial connection  (as in rs232) might also be an interesting option. Salvador

I have one of these that will be connected to my Dragon, but through a
microcontroller as part of a larger project. The idea is that the
microcontroller "talks" DriveWire, and the wireless modem can be
addressed through a DriveWire virtual serial channel. Although a bit
more indirect, this method fits nicely into existing software
infrastructure, and the Dragon/CoCo doesn't have to be stuck listening
to the bit-banger.

It would maybe be possible to connect the wifi modem directly to the
bit-banger port also (with adequate voltage level conversion), but I
would think something like an UART like Gene mentions would be better.

Yes, the module does WPA2.
