带Node.JS的USB灯HID控制&;节点usb-仅闪存?
我有一个Delcom USB light-think build light(),我正试图从node.js控制它(在Ubuntu上运行,如果这有什么不同的话) 我正在使用node usb(),我可以连接并声明设备。我甚至可以让它“闪烁”(就像你第一次插上电源时一样),但我无法让它保持点亮,更不用说改变颜色了带Node.JS的USB灯HID控制&;节点usb-仅闪存?,node.js,usb,hid,light,Node.js,Usb,Hid,Light,我有一个Delcom USB light-think build light(),我正试图从node.js控制它(在Ubuntu上运行,如果这有什么不同的话) 我正在使用node usb(),我可以连接并声明设备。我甚至可以让它“闪烁”(就像你第一次插上电源时一样),但我无法让它保持点亮,更不用说改变颜色了 var usb_driver = require("../usb.js"), assert = require('assert'); // setup our vars var

console.log(theLightInterface.claim());

theLight.controlTransfer(new Buffer(10), 0x88, 0xc8, 0x0635, 0x04, function() { console.log("LED toggled") }, 0);
当你运行这个,它告诉我有一个设备,它声称它,它甚至闪烁,但它只是不会停留
有没有关于下一步该转向哪里的想法
这是否与Node.js关闭以及“闪存”是计算机再次控制USB端口有关?以下是一些更新的代码:
var theLightInterface = theLightInterfaces[0]
console.log("Claiming the LIGHT interface for further actions " + theLightInterface)
for(var inter in theLightInterface){
console.log("Name: "+ inter)
console.log("Value: "+ theLightInterface[inter])
}
console.log("Is Active: "+ theLightInterface.isKernelDriverActive() )
console.log("Release Kernel: "+ theLightInterface.detachKernelDriver() )
console.log("Claim Interface: "+ theLightInterface.claim() )
theLight.controlTransfer(new Buffer(0), 0x12, 0xc8, 0x04, 101, function() { console.log("LED toggled") }, 1000)
结果是:
Is Active: 1
Release Kernel: undefined
Claim Interface: undefined
设置了0x12和0xc8后,指示灯确实会闪烁/闪烁-但我认为我无法控制USB驱动程序好吧,首先你应该将逗号替换为分号,而且,在语句的每一个结尾都加上分号是一个好习惯;哈哈,你知道我来自哪里;是必需的;)但对于node,人们似乎不使用它。
