“high” when inactive. The pushbutton functions in either the touch or
proximity mode.
Proximity
The device has two modes of operation: touchpad, and proximity. The
device is set to proximity mode by command over the USB. In Proximity
Mode the device sends make and break codes over the USB corresponding to
the current status of the proximity sensor. Proximity is detected using the
mutual projected capacitance method.
Backlight
There are four lighting elements that make up the backlight. Each element
can be individually set to on or off. Additionally the four elements together
(with a single setting) may be set to one of 256 different brightness levels.
In the sample unit provided with the SDK, the backlight has a Grayhill logo,
but the standard device has a solid white backlight. Custom logo printing is
available for the MTRE.
Highlight Ring
There are 12 lighting elements that make up the highlight ring. Each element
can be individually set to on or off. Additionally the twelve elements
together (with a single setting) may be set to one of 256 different brightness
levels. The highlight ring comes in four different colors: white, blue, red, or
green. Custom colors are also available.
