Platform Support

eduku-hid supports Node.js v6 and upwards. For versions before that, you will need to build from source. The platforms, architectures and node versions eduku-hid supports are the following. In general we try to provide pre-built native library binaries for the most common platforms, Node and Electron versions.

We strive to make eduku-hid cross-platform so there's a good chance any combination not listed here will compile and work.

Installation

For most "standard" use cases (macOS, Windows, Linux x86), eduku-hid will install like a standard npm package:

npm install eduku-hid

Usage

Config eduku client listener

var eduku = require("eduku-hid");
eduku.config({
	//初始化
	TouchSensorAngle: "0", // 书写框摆放角度， 0: 0度，1: 180度，2: 90度，3: 270度
	template: {}, // 模板详情
	on: {
		DeviceInfo: function (device) {
			// 设备信息
			//console.log("DeviceInfo:", data);
		},
		TouchData: function (touch) {
			//触摸数据
			//console.log("TouchData:", touch);
		},
		data: function () {}, // hid data
		error: function (type, error) {}, // hid error
	},
});

Sample config:

var eduku = require('eduku-hid');
eduku.config({  //初始化
    TouchSensorAngle: "0",// 书写框摆放角度， 0: 0度，1: 180度，2: 90度，3: 270度
    template: {
        rubWidth: "",//该值不能为数字0
        rubHeight: "",//该值不能为数字0

        share_x: 330,
        share_y: -45,
    },
    on: {
        DeviceInfo: function(device){ // 设备信息
            //console.log("DeviceInfo:", data);
        },
        TouchData: function(touch){ //触摸数据
            console.log("TouchData:", touch);
        },
        data: function(){}  // hid data
        error: function(type, error){}  // hid error
    }
});
// or config listeners via "on" function
    eduku.on('TouchData', function(touchdata){
        //
    })
    eduku.on('error', function(err){
        //err.code
    })
