About The zeppos_timer.js

An accurate timer for ZeppOS. ZeppTimer is a small and refined JavaScript class that provides an accurate timer for the ZeppOS system.

Here's why:

• In all versions of ZeppOS, there is a significant time discrepancy between the system's timer and the actual time due to underlying issues with the system. To achieve more accurate timing, I implemented a simple but effective approach to reduce timing errors and packaged it into ZeppTimer.

• Furthermore, in ZeppOS 2.x, the official approach to timer components was replaced with setTimeOut and cleanTimeOut, requiring logic adjustments when migrating ZeppOS 1.0 applications that use timers to ZeppOS 2.x and above. Using the ZeppTimer library can save developers the cost of migration.

Use the Usage to easily get started.

Getting Started

The content here will help you get familiar with the program quickly.

Prerequisites

Before using this library, please make sure you already have an understanding of ZeppOS applet development, you can refer to the ZeppOS official documentation. Also, you need a code editor(Like Microsoft VSCode) and knowledge of JavaScript.

Installation

1. To use this library, you need to create a ZeppOS applet project first.refer to the ZeppOS quick start.

2. Please download the latest zeppos_timer.js file in the Releases, and place zeppos_timer.js in the libs/ directory of the root of the applet

3. Add a reference to zeppos_timer.js in the project

import { ZeppTimer } from "../libs/zeppos_timer"; // Replace with the path to your zeppos_timer.js

At this point, you're ready to use the zeppos_timer.js library

Usage

Then create a new instance of the class:

const timer = new ZeppTimer(() => {
  console.log("Tick!");
}, 1000);

The first argument to the ZeppTimer constructor is a callback function that will be called on each tick of the timer. The second argument is the time interval between ticks, in milliseconds.

To start the timer, call the start method:

timer.start();

To stop the timer, call the stop method:

timer.stop();
