通过 USB 端口发送和接收数据 [英] Sending and receiving data over USB port

问题描述

我想通过 USB 端口向设备(从我的 vista 电脑)发送/接收数据.是否有免费/廉价的图书馆可以做到这一点，以及这个项目的参与程度(不考虑发送或接收的内容)?

I'd like to send/receive data over a USB port to a device (from my vista pc). Is there a free/cheap library out there that can do this, and how involved would this project be (not taking into account what's being sent or received) ?

推荐答案

你没有指定这里发生了什么.设备是否已经存在?它已经是 USB 设备了吗?

You don't specify what's going on here. Does the device already exist? Is it already a USB device?

如果您已经有 USB 设备，那么制造商应该可以提供帮助.

If you already have a USB device, then the manufacturer should be able to help.

如果您正在构建设备，那么您可能需要查看 USB 转串口适配器(通常根本不需要特殊驱动程序)或 FTDI - 他们制作了许多通常不需要的易于使用的 USB 芯片，或者在 Windows 下带有适当的驱动程序.我曾多次使用他们的芯片，他们从未给我带来任何麻烦.

If you are building the device, then you might want to look at something like a USB to serial adapter (which generally require no special drivers at all) or something from FTDI - they make a number of easy-to-use USB chips that generally don't need, or come with appropriate drivers under windows. I've worked with their chips on a couple of occasions and they've never given me any trouble.
