Can the EMX usb ports be used as digital input/output lines (from the usb connector)…it would be handy for some reasons when the board is already sealed up in a case. If it can be used, can the connector also be switched back to be used as normal usb host?
I was looking for schematics to see how the emx usb ports are implemented (direct from the processor?), but couldn’t find the schematics.
Thanks, but I still don’t find the [em]schematic[/em]…need that to see if the lines run right from the cpu to the connector in some manner.
I did find some usb i/o modules that just plug in…might work, but maybe not as speedy as direct i/o manipulation from the cpu. How fasrt could you control i/o with one of these modules? ms? us? ns?
