一. 需求:
获取eGalaxTouch的输入设备节点
二. /proc/bus/input/devices 内容:
root@freescale /proc/bus/input$ cat /proc/bus/input/devices
I: Bus=0019 Vendor=0001 Product=0001 Version=0100
N: Name="gpio-keys"
P: Phys=gpio-keys/input0
S: Sysfs=/devices/platform/gpio-keys/input/input0
U: Uniq=
H: Handlers=kbd event0
B: PROP=0
B: EV=3
B: KEY=100000 0 0 0
I: Bus=0003 Vendor=0eef Product=7201 Version=0210
N: Name="eGalax Inc. eGalaxTouch EXC7200-0031v1000"
P: Phys=usb-fsl-ehci.1-1.3/input0
S: Sysfs=/devices/platform/fsl-ehci.1/usb2/2-1/2-1.3/2-1.3:1.0/input/input1
U: Uniq=
H: Handlers=cpufreq_interactive
B: PROP=0
B: EV=1b
B: KEY=421 0 30001 0 0 0 0 0 0 0 0
B: ABS=100 3f
B: MSC=10
I: Bus=0006 Vendor=0eef Product=0020 Version=0001
N: Name="eGalaxTouch Virtual Device for Multi"
P: Phys=
S: Sysfs=/devices/virtual/input/input2
U: Uniq=
H: Handlers=cpufreq_interactive event1
B: PROP=2
B: EV=b
B: KEY=400 0 0 0 0 0 0 0 0 0 0
B: ABS=6608000 1000003
I: Bus=0006 Vendor=0eef Product=0010 Version=0001
N: Name="eGalaxTouch Virtual Device for Single"
P: Phys=
S: Sysfs=/devices/virtual/input/input3
U: Uniq=
H: Handlers=event2
B: PROP=2
B: EV=b
B: KEY=30000 0 0 0 0 0 0 0 0
B: ABS=3
root@freescale /proc/bus/input$
三. 解决方法:
1. 采用shell脚本的进行解决;
2. shell脚本如下:
inputCheckLine=`cat /proc/bus/input/devices | grep -n "Vendor=0eef" | grep "Product=0020 Version=0001"| awk -F: '{print $1}'`
touchEvent=`sed -n "$((${inputCheckLine}+5))p" /proc/bus/input/devices | grep -o "event."`
四. 实际应用:
......
while [ -z $touchEvent ]
do
inputCheckLine=`cat /proc/bus/input/devices | grep -n "Vendor=0eef" | grep "Product=0020 Version=0001"| awk -F: '{print $1}'`
touchEvent=`sed -n "$((${inputCheckLine}+5))p" /proc/bus/input/devices | grep -o "event."`
echo "please hang up USB TOUCH !"
usleep 10
done
......
export TSLIB_TSDEVICE=/dev/input/${touchEvent}
export QWS_MOUSE_PROTO=tslib:/dev/input/${touchEvent}
