Dial on Display: Explained
While touchscreens are intuitive and simple to use interfaces, some users long for mechanical tactile controls for certain functions. A great example is rotary knobs for adjustment of the volume on a radio or the temperature in the car. aXiom can support a feature called Dial on Display which enables mechanical knobs to work in conjunction with the touchscreen.
One cool feature is that these dials can be back illuminated, and the display can actually shine through the centre of the dial. A huge advantage of the aXiom family of chips is the dial does not make contact with the screen, so it is a reliable solution for automotive environments!
