linux下开发NFC读写器

linux下使用NFC读卡器，基于QT5开发

创建工程，引入lib
- 开始编写代码

创建工程，引入lib

创建一个QT工程，如果是控制台程序，则去掉gui

QT -= gui

引入lib库

LIBS += -L$$PWD/lib -lyw60x

这里需要将libyw60x.so库文件放在工程目录下的lib目录下。
工程文件如下所示：

QT -= guiCONFIG += c++11 console
CONFIG -= app_bundle
CONFIG += static
CONFIG -= shared# The following define makes your compiler emit warnings if you use
# any Qt feature that has been marked deprecated (the exact warnings
# depend on your compiler). Please consult the documentation of the
# deprecated API in order to know how to port your code away from it.
DEFINES += QT_DEPRECATED_WARNINGS# You can also make your code fail to compile if it uses deprecated APIs.
# In order to do so, uncomment the following line.
# You can also select to disable deprecated APIs only up to a certain version of Qt.
#DEFINES += QT_DISABLE_DEPRECATED_BEFORE=0x060000    # disables all the APIs deprecated before Qt 6.0.0SOURCES += \main.cpp# Default rules for deployment.
qnx: target.path = /tmp/$${TARGET}/bin
else: unix:!android: target.path = /opt/$${TARGET}/bin
!isEmpty(target.path): INSTALLS += targetLIBS += -L$$PWD/lib -lyw60xHEADERS += \libyw60x.h

开始编写代码

Main程序如下所示：
