qt利用cyapi连接usb通信

MinGW编译的32位的CyAPI.lib，可以windows上的qt中使用，官方和网上的多数都是基于msvc编译的，在qt中没法用，这个可以！

CYPRESS的USB开发库文件，用于VC，BC开发，非常好！

This is a simple Qt app that can do transfers over USB. Prerequisites 1. Download Qt from http://qt-project.org/downloads. Make sure to specifically download Qt x.y.z for Windows (MinGW 4.8.2, OpenGL) 2. The installer comes with MinGW but if it doesn’t, then download it from http://www.mingw.org/ 3. The SuperSpeed USB Suite from Cypress. You will also need the source code for CyAPI.lib as we’ll need to recompile it Compiling CyAPI The C++ USB API from Cypress needs to be recompiled with MinGW before we use it to build our project. Extract the source code to a folder and then run the following in a command prompt: set PATH=%PATH%;C:\Qt\Tools\mingw482_32\bin mingw32-make % And this requires a Makefile with the following contents: all:

CyAPI源码，可以自行编译CyAPI.lib

做USB通信设计时，编写客户端应用软件，在VC下需要用到头文件

This directory contains source code and build script for CyUSB3 WDF kernel mode USB generic driver. This driver source code is readily compliable for operating system such as Windows 10, 8.1, 8, 7, Vista and XP (32 bit and 64 bit) Pre-requisite for driver source compilation For building driver for Windows 10, 8.1, 8 and 7 driver needs Visual Studio 2015 and the latest version of WDK 10. Vista and XP driver. WDK 7.1. Following projects source code is included in this package. 1. CyAPI C++ Static Library. 2. CyUSB C# DLL.

该压缩包包含MinGW编译的64位的CyAPI.lib，可以在windows上的qt中使用，官方和网上的多数都是基于msvc编译的，在qt中没法用。本人也是被该问题困扰了几天，所以希望对遇到该问题的朋友有所帮助，里面有使用的步骤说明和我建的一个QT工程，可以直接打开运行。
