Qt程序自启动说明

Linux系统启动后，会自动执行/etc/init.d中的rcS脚本。因此，只要在该脚本中增加程序的运行运行环境和启动该程序即可。以下是rcS的内容：

#!/bin/sh

if [ ! -d /system/vendor/ ]; then
    mkdir -p /system/vendor/
    ln -s /lib/modules/`uname -r`/ /system/vendor/modules

# Start all init scripts in /etc/init.d
# executing them in numerical order.
#
for i in /etc/init.d/S??* ;do

     # Ignore dangling symlinks (if any).
     [ ! -f "$i" ] && continue

     case "$i" in
	*.sh)
	    # Source shell script for speed.
	    (
		trap - INT QUIT TSTP
		set start
		. $i
	    )
	    ;;
	*)
	    # No sh extension, so fork subprocess.
	    $i start
	    ;;
    esac
done

echo /sbin/mdev > /proc/sys/kernel/hotplug
mdev -s

#/etc/adb_conf.sh start &

MODEL=$(cat /proc/device-tree/model)
if [[ "$MODEL" = "sbc-t113" ]];then
#chip=t113_i
	tinymix set "ADC2 Input MIC2 Boost Switch" 1 > /dev/null

if [ ! -f "/usr/lib/libcrypto.so.1.0.0" ]; then
    ln -s /usr/lib/libcrypto.so.1.1 /usr/lib/libcrypto.so.1.0.0
fi

if [ ! -f "/usr/lib/libssl.so.1.0.0" ]; then
    ln -s /usr/lib/libssl.so.1.1 /usr/lib/libssl.so.1.0.0
fi

. /etc/qtenv_capx.sh && /embfly_test/DeviceTest &

看最后一行，“. /etc/qtenv_capx.sh”这语句表示初始化QT的运行环境，qtenv_capx.sh 脚本是配置qt使用电容屏控制器的配置脚本，“/embfly_test/DeviceTest &”这个语句表示运行/embfly_test/DeviceTest程序，用户将DeviceTest替换为自己的程序名，用户程序即可自动运行。

qtenv_capx.sh脚本内容如下：

本脚本适配了三款电容式触摸，它们分别是ILITEK ILITEK-TP/gt9xxnew_ts（i2c接口，控制器为gt911等）/wch.cn USB2IIC_CTP_CONTROL（hid-multitouch协议），脚本将自动识别它们其中的某一个。

另外，我司也为用户提供了qt使用电阻式触摸屏配置脚本qtenv_rtp.sh，脚本内容如下：

点击查看代码

export  QTDIR=/usr/local/Qt_5.12.5
if [ -d $QTDIR ];then

	export  QT_ROOT=$QTDIR
	export  PATH=$QTDIR/bin:$PATH
	export  LD_LIBRARY_PATH=$QTDIR/lib:/usr/lib/cedarx/:$LD_LIBRARY_PATH

	export QT_QPA_PLATFORM_PLUGIN_PATH=$QT_ROOT/plugins
	export QT_QPA_PLATFORM=linuxfb:tty=/dev/fb0
	export QT_QPA_FONTDIR=$QT_ROOT/fonts

	TouchDevice=sunxi-ts
	for InputDevices in /sys/class/input/input*
	do
		DeviceName=`cat $InputDevices/name`
		if [ $DeviceName == $TouchDevice ];then
		   TouchDeviceNum=${InputDevices##*input}
		   #export QT_QPA_EVDEV_TOUCHSCREEN_PARAMETERS=/dev/input/event$TouchDeviceNum
		   echo "add "/dev/input/event$TouchDeviceNum "to Qt Application."
		   break
		fi
	done
	if [ ! -n "$TouchDeviceNum" ]; then
	 echo "Error:Input device $TouchDevice can not be found,plz check it!"
	fi

	export QT_QPA_PLATFORM=linuxfb
	#export QT_QPA_GENERIC_PLUGINS=evdevtouch
	#export QT_QPA_EGLFS_INTEGRATION=eglfs_mali
	#export QT_QPA_FB_HIDECURSOR=1
	#export QT_QPA_EGLFS_HIDECURSOR=1
	#export QT_QPA_EGLFS_ROTATION=90

	export QWS_MOUSE_PROTO=
	#export DBUS_SESSION_BUS_ADDRESS=`cat /tmp/dbusaddr`
	mkdir -p /dev/shm	
	ulimit -c unlimited
	echo "find qt5 installed done"                                     
fi

另外，要使用电阻式触摸屏，务必通过tslib的工具对电阻式触摸屏进行校正，校正后方可使用。校正前，请务必先检查/etc/profile.d目录下存在有tslib.sh脚本，它是 tslib工作的环境变量，该脚本会在系统启动后自动执行，tslib.sh脚本内容如下：

点击查看代码

#!/bin/sh

if [ -e /dev/input/touchscreen0 ]; then
    TSLIB_TSDEVICE=/dev/input/touchscreen0

    export TSLIB_TSDEVICE
    export TSLIB_FBDEVICE=/dev/fb0
    export TSLIB_CALIBFILE=/etc/pointercal
    export TSLIB_CONFFILE=/etc/ts.conf
    export TSLIB_PLUGINDIR=/usr/lib/ts
    export TSLIB_CONSOLEDEVICE=none
    export TSLIB_TSEVENTTYPE=input
fi

这些变量解析如下：

点击查看代码

#TSLIB
export TSLIB_TSDEVICE=/dev/input/touchscreen0       # 指定触摸屏设备
export TSLIB_CALIBFILE=/etc/pointercal                # 指定触摸屏校准文件pointercal存放位置
export TSLIB_CONFFILE=/etc/ts.conf                   # 指定TSLIB配置文件的位置
export TSLIB_PLUGINDIR=/usr/lib/ts                   # 指定触摸屏插件所在路径
export TSLIB_FBDEVICE=/dev/fb0                      # 指定帧缓冲设备
