# imx6q yocto增加tslib支持 #

## yocto修改 ##

修改sources/meta-qt5/recipes-qt/qt5/qtbase\_git.bb  
将

PACKAGECONFIG_DEFAULT ?= "dbus udev evdev widgets tools libs freetype tests sql-sqlite

修改为

PACKAGECONFIG_DEFAULT ?= "dbus udev evdev tslib widgets tools libs freetype tests sql-sqlite

增加tslib支持,这时只有tslib库没有校准程序，还需要增加tslib-calibrate  
修改yocto根目录下编译脚本

    }
    
    parse_args $@
    echo "DISTRO:$DISTRO BUILD_DIR:$BUILD_DIR "
    CONF_DIR=$BUILD_DIR
    source ./fsl-setup-release.sh -b $BUILD_DIR
    echo "conf:$TOP/$CONF_DIR/conf/local.conf"
    echo "IMAGE_INSTALL_append= \"qtvirtualkeyboard \"" >> $TOP/$CONF_DIR/conf/local.conf
    echo "IMAGE_INSTALL_append= \"ppp \"" >> $TOP/$CONF_DIR/conf/local.conf
    echo "IMAGE_INSTALL_append= \"tslib-calibrate \"" >> $TOP/$CONF_DIR/conf/local.conf
    # Remove connman
    #echo "IMAGE_INSTALL_remove = \"connman\"" >> $TOP/$CONF_DIR/conf/local.conf
    #echo "IMAGE_INSTALL_remove = \"connman-client\"" >> $TOP/$CONF_DIR/conf/local.conf
    #echo "IMAGE_INSTALL_remove = \"connman-gnome\"" >> $TOP/$CONF_DIR/conf/local.conf
    # Add NetworkManager
    #echo "IMAGE_INSTALL_append = \"networkmanager\"" >> $TOP/$CONF_DIR/conf/local.conf
    #echo "IMAGE_INSTALL_append = \"modemmanager\"" >> $TOP/$CONF_DIR/conf/local.conf
    
    clean_build
    build_uboot
    build_kernel
    build_system
    build_sdk
    build_qt5
    #build_gui

增加了

echo "IMAGE_INSTALL_append= \"tslib-calibrate \"" >> $TOP/$CONF_DIR/conf/local.conf

执行./build.sh -b fb  
使用时增加环境变量

export QT_QPA_EGLFS_TSLIB=1
    export TSLIB_TSDEVICE=/dev/input/touchscreen0

这里QT\_QPA\_EGLFS\_TSLIB环境变量一定要在TSLIB\_TSDEVICE之前,要不然ts\_calibrate点击会没反应  
在增加自动校准，功能

if [ -c ${TSLIB_TSDEVICE} ]; then
    	if [ ! -f /etc/pointercal ] ; then
    		ts_calibrate
    	fi
    fi

最后启动默认demo  
/usr/share/qt5everywheredemo-1.0/QtDemo  
触摸正常
