/* Design notes: The tranzport is a unique device, basically a
|
|
20 lcd gui with 22 shift keys and 8 blinking lights.
|
|
|
|
As such it has several unique constraints. The device exerts flow control
|
|
by having a usb write fail. It is pointless to retry madly at that point,
|
|
the device is busy, and it's not going to become unbusy very quickly.
|
|
|
|
So writes need to be either "mandatory" or "unreliable", and therein
|
|
lies the rub, as the kernel can also drop writes, and missing an
|
|
interrupt in userspace is also generally bad.
|
|
|
|
It will be good one day, to break the gui, keyboard, and blinking light
|
|
components into separate parts, but for now, this remains monolithic.
|
|
|
|
A more complex surface might have hundreds of lights and several displays.
