你看下 ts_calibrate 能否校正？

1. 板子是不是用荔枝派Zero, 是不是用主线u-boot和主线Linux?
2. rootfs是不是用buildroot编译出来的?
3. 用ts_test测试输出来的坐标有没有问题？
4. 这个帖子 荔枝派Zero V3s开发板入坑教程 有TF卡的文件下载，你试一试，先排除硬件问题。

晕哥，我使用qt5.4.1的程序发现点击触摸屏没有反应
（1）执行命令/opt/tslib/bin/ts_calibrate的结果如下
xres = 480, yres = 272
Took 4 samples...
Top left : X = 2996 Y = 1998
Took 4 samples...
Top right : X = 2695 Y = 2492
Took 3 samples...
Bot right : X = 2126 Y =  696
Took 4 samples...
Bot left : X = 2409 Y = 2423
Took 2 samples...
Center : X = 3125 Y = 1692
677.600098 -0.102749 -0.087760
527.730103 -0.127696 -0.027290
Calibration constants: 44407200 -6733 -5751 34585320 -8368 -1788 65536
（2）执行cat /dev/input/event1命令
我点击触摸屏会有一些乱码出现呢
（3）cat /etc/profile的结果如下
export PATH=/bin:/sbin:/usr/bin:/usr/sbin

if [ "$PS1" ]; then
        if [ "`id -u`" -eq 0 ]; then
                export PS1='# '
        else
                export PS1='$ '
        fi
fi

export PAGER='/bin/more '
export EDITOR='/bin/vi'

# Source configuration files from /etc/profile.d
for i in /etc/profile.d/*.sh ; do
        if [ -r "$i" ]; then
                . $i
        fi
        unset i
done
source /etc/init.d/rcS

#tslib configure

export QWS_MOUSE_PROTO=Tslib:/dev/input/event1
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/opti/tslib/lib:/home/gec/v3s/qt5.4.1-arm/lib:/usr/lib
（3）可是我运行qt程序时就没有反应了输出结果：
# ./music_download
QTsLibMouseHandler "tslib" "/dev/input/event1"

请晕哥帮忙分析下。
