Template counter demo user guide

Template is the counter demonstration included with the application starter project. It demonstrates a minimal interactive app rather than managing device hardware. The unchanged example executable is lilygo-ui-template.

Before you start

• Install the Template example and its shared font dependency.
• Use a display environment with touch or pointer input.
• No sensors, serial devices, account, or network connection are required.

Applications derived from the template may have a different name and entirely different controls. This guide covers the unchanged Template counter only.

Open and use the counter

1. Open Template in Launcher when the example is installed.
2. Find the central Counter card.
3. The initial value is 0; tap + to change it to 1.
4. Each subsequent + tap adds 1.
5. Tap - to subtract 1.
6. Tap Reset to return immediately to 0.

Control	Effect
+	Adds one, up to 999.
-	Subtracts one, down to 0.
Reset	Sets the value to zero.

Values do not wrap at the boundaries: 0 cannot become negative and 999 cannot increase further. Reset has no confirmation step and affects only the current demonstration value.

Try different screen sizes

Resize the desktop window or change orientation on a supported device. The card and control spacing adapt to the available width. There is no portrait, landscape, or compact-mode selector. A layout change alone does not reset the running counter.

A short interaction check

1. Launch the example and confirm 0.
2. Tap + three times and confirm 3.
3. Tap - once and confirm 2.
4. Resize the window and confirm the value remains 2 and the controls are usable.
5. Tap Reset and confirm 0.
6. Tap - again and confirm it remains 0.

This checks counter behavior and interface response, not physical device functionality.

Data and exit

The counter is stored only in this application instance's memory. There is no save or export function, and restarting begins again at 0. The example has no login, settings page, history, or background timer. Close the desktop window or use the system's application exit control to finish.

Troubleshooting

Symptom	Explanation
Template is absent from Launcher	It is a development example and may not be included in a production image.
The name or interface differs	A developer may have replaced the template; these steps no longer describe that app.
The value stops at 999	This is the example's defined upper limit.
The count disappears after reopening	The current example does not persist the count.

Based on the local Template Counter view, Model, and ViewModel implementation. For creating an application from this starter project, use the development documentation.
