The MTRE page allows interaction with the features exclusive to the MTRE.
If a finger or fingers are placed on the touchscreen, while in touch mode, its
movements will be tracked in the circular area on the left hand side of the
screen.
To demonstrate the push button function, the indicator under the heading
“PUSH BUTTON” illuminates when the MTRE push button is activated.
To demonstrate the encoder function, turning the MTRE knob clockwise
causes the counter under the heading “ENCODER COUNTS” to increment,
while turning it counter-clockwise causes it to decrement.
To demonstrate the brightness control function, the slider bars under the
headings “Backlight Intensity” and “Highlight Intensity” can be used to
control the brightness of the backlight and highlight rings respectively.
The MTRE can be placed in proximity mode by selecting the “PROXIMITY
MODE” option button. To demonstrate the proximity mode function, the
circular area where the touch movements are tracked will turn green when
proximity is detected. To return to touch tracking, select the “TOUCH
MODE” option button.
Multi-Touch Ring Encoder Overview
We’ve demonstrated some of the functions of the MTRE with a simple demo
application - but we’ve only scratched the surface of its possibilities. While
the demo can show some examples of the ways the MTRE can be used, it
cannot match your imagination of how it might be used. In this section we’ll
cover the technical details of the MTRE so that you can appreciate its
flexibility.
