1.配置
➜ tslib-1.4 ./autogen.sh
➜ tslib-1.4 source ../../set_env.sh
➜ echo "ac_cv_func_malloc_0_nonnull=yes" > arm-linux.cache
➜ ./configure --host=arm-linux --cache-file=arm-linux.cache --prefix=$(pwd)/_install
CC=arm-linux-gnueabihf-gcc
- 编译安装
make
make install
3.查看
➜ cd _install/bin
➜ file ts_calibrate

报错
error: ‘ABS_MT_TOOL_X’ undeclared (first use in this function)
解决:
a. 修改config.h文件:
vim config.h +4
+ #define ABS_MT_SLOT 0x2f /* MT slot being modified */
+ #define ABS_MT_TOUCH_MAJOR 0x30 /* Major axis of touching ellipse */
+ #define ABS_MT_TOUCH_MINOR 0x31 /* Minor axis (omit if circular) */
+ #define ABS_MT_WIDTH_MAJOR 0x32 /* Major axis of approaching ellipse */
+ #define ABS_MT_WIDTH_MINOR 0x33 /* Minor axis (omit if circular) */
+ #define ABS_MT_ORIENTATION 0x34 /* Ellipse orientation */
+ #define ABS_MT_POSITION_X 0x35 /* Center X touch position */
+ #define ABS_MT_POSITION_Y 0x36 /* Center Y touch position */
+ #define ABS_MT_TOOL_TYPE 0x37 /* Type of touching device */
+ #define ABS_MT_BLOB_ID 0x38 /* Group a set of packets as a blob */
+ #define ABS_MT_TRACKING_ID 0x39 /* Unique ID of initiated contact */
+ #define ABS_MT_PRESSURE 0x3a /* Pressure on contact area */
+ #define ABS_MT_DISTANCE 0x3b /* Contact hover distance */
+ #define ABS_MT_TOOL_X 0x3c /* Center X tool position */
+ #define ABS_MT_TOOL_Y 0x3d /* Center Y tool position */
b. 修改ts_uinput.c 文件:
vim tools/ts_uinput.c +22
+ #include <config.h>
- 重新编译安装
make
make install

5.arm开发板上测试
报错:
ts_config: No such file or directory
平台:全志 A40I
库版本:tslib-1.14
1.配置
➜ tslib-1.14 ./autogen.sh
➜ tslib-1.14 source ../../set_env.sh
➜ echo "ac_cv_func_malloc_0_nonnull=yes" > arm-linux.cache
➜ ./configure --host=arm-linux --cache-file=arm-linux.cache --prefix=$(pwd)/_install
CC=arm-linux-gnueabi-gcc
- 编译安装
make
make install
3.查看
➜ cd _install/bin
➜ file ts_calibrate
ts_calibrate: ELF 32-bit LSB executable, ARM, EABI5 version 1 (SYSV),

一步成功。
拷贝测试:
cd _install
cp * /文件系统根目录/ -rfd
- -rfd :强制拷贝_install/下所有文件到/文件系统根目录/下,-d:保持链接,原来的是链接,复制过来的还是链接
安装使用
Step1. 修改参数:
vi /etc/ts.conf
# module_raw input
改为:
module_raw input
Step2. 配置触摸屏环境:
export TSLIB_TSDEVICE=/dev/event0
export TSLIB_CALIBFILE=/etc/pointercal
export TSLIB_CONFFILE=/etc/ts.conf
export TSLIB_PLUGINDIR=/lib/ts
export TSLIB_CONSOLEDEVICE=none
export TSLIB_FBDEVICE=/dev/fb0
- TSLIB_TSDEVICE:ts设备文件(触摸屏),可能为/dev/eventx也可能为/dev/input/eventx;可用使用cat /proc/input/devices或evtest(依赖文件系统中是否包含evtest工具)进行确认;
- TSLIB_CALIBFILE:校验文件(calibrate file),存放校验
- TSLIB_CONFFILE:配置文件
- TSLIB_PLUGINDIR:插件文件,也有可能位于/usr/lib/ts;根据实际情况配置
- TSLIB_CONSOLEDEVICE:终端控制台设为NULL
- TSLIB_FBDEVICE:fb设备文件(LCD):fb0
Step3. 校验测试:
ts_calibrate
运行校验,屏幕会出现5次小黑点让用户触摸,然后生成/etc/pointercal文件,并存5个小黑点值
