Dial Settings

This page gives you more information about the selected dial as well as the option to view current dial image, change dial name, identify dial and set dial behavior.

Dial information

Section header shows dial name that is used to easily identify each dial in the system.

It also includes a table that shows some basic information about the dial

Cell	Value	Description
Dial status	Online / Offline	Shows if dial is currently present in the system
Dial UID	UID	Unique identifier that was assigned to this dial during manufacturing
Dial generation	VU1	What is the generation/configuration of this dial.
Dial type	HUB+Dial / Dial	Identifies if this dial is acting as dial and hub or dial
Firmware version	Firmware timestamp	Flag indicating firmware version
Firmware build	build hash	Firmware build hash
Hardware revision	hardware stamp	Flag indicating hardware and firmware configuration
Protocol version	v1	Indicates which VU protocol(s) this hardware supports
Needle update period	x ms	How often (in ms) does the dial value change
Max needle step per period	x %	How much (in %) can the dial value change per each period
Backlight update period	x ms	How often (in ms) does the backlight change
Max backlight step per period	x %	How much (in %) can the backlight value change per each period

Note

Dial/backlight update period and max step value per period define the behaviour of the dial.
These can be fine tuned to allow the dial to be very responsive or to gently change between values.
You can read these as

"Every [update period] milliseconds the dial value/backlight can change by maximum of [step per period] percent.

Dial background

This section shows image that is currently displayed on the dial e-ink display.

Set dial name

Here you can assign a name to the dial.

By default, dials will not have the name set.

Identify dial

Since dials do not come with a name assigned and only have UID. It is convenient to have a way to identify a physical dial that you are configuring.

You can click on Red, Green, Blue and the dials backlight will be set to that color and also nedle will be set to 50% value. This can come in handy to identify which dial you are currently configuring.

Dial behaviour

These are default presets that allow you to quickly change dial behaviour.
Dial behaviour is defined by a update period and maximum step. This determines how often the dial value or backlight will update and also what is the maximum change it can make between each period.

Preset	Values	Description
Responsive	Indicator 50ms/20% Backlight 50ms/20%	Dial indicator and backlight will change values rapidly. Dial indicator has tiny but non-negligible mass. When there is a large dial value change, indicator can overshoot and then undershoot couple of times (oscillate) due to indicators mass.
Balanced	Indicator 50ms/5% Backlight 50ms/10%	Dial indicator and backlight will change relatively fast but the dial indicator should not oscillate too much on large value changes.
Smooth	Indicator 50ms/1% Backlight 50ms/5%	Dial indicator and backlight will change gradually. This gives the effect that backlight is slowly fading between colors and the value indicator will move smoothly between values.

Note

These are presets defined for convenience and as a quick demo for users to try out.
Each application driving the dial can change these values individually and for each individual dial at any time and to whichever value the app/end-user requires.
