I like the concept of the wifi module connecting via ethernet. The processor chip has two ethernet ports on an internal switch, the idea is that one goes to the outside world and the other goes to the wifi. As far as the processor and software is concerned the wifi is just another device on the network. You literally don't have to care whether something is coming from wired or wifi. The software just has to worry about a single ethernet connection. Any wifi setup issues are dealt with by browsing to the wifi web page, either through the wifi or wired port, so the firmware on the processor doesn't have to know anything about it. I just think it makes things so much simpler from a software perspective. Since I am thinking about configuration of the player be controlled by an internal web server, this can just link to the wifi module's web page. Since it is connected through a hardware switch, you can always get to the wifi configuration via a hardwired connection to the player. Each USB port has it's own separate controller, each of which can either be a device or host. The processor is a TI AM3358, the technical reference manual gives a lot of detail on the USB subsystem: http://www.ti.com/lit/ug/spruh73g/spruh73g.pdf John S. ------------------------------------------------------------------------ JohnSwenson's Profile: http://forums.slimdevices.com/member.php?userid=5974 View this thread: http://forums.slimdevices.com/showthread.php?t=97881 _______________________________________________ discuss mailing list [email protected] http://lists.slimdevices.com/mailman/listinfo/discuss
