Library to provide a common interface to touchscreen and allow touchscreen events filtering or calibrating...
Compiling
- Be sure to have libtool package installed (tested with 1.5.22-4 version). Otherwise you will have following errors:
configure.ac:25: error: possibly undefined macro: AC_DISABLE_STATIC If this token and others are legitimate, please use m4_pattern_allow. See the Autoconf documentation. configure.ac:26: error: possibly undefined macro: AC_ENABLE_SHARED configure.ac:27: error: possibly undefined macro: AC_LIBTOOL_DLOPEN configure.ac:28: error: possibly undefined macro: AC_PROG_LIBTOOL
- Be sure to have automake-1.6 or higher package installed (tested with 1.7 version -> working and 1.9.6 -> not working !). After automake package installation don't forget to update your /etc/alternatives/automake and /etc/alternatives/aclocal symlinks (tested on Ubuntu).
lrwxrwxrwx 1 root root 20 2007-06-27 21:43 /etc/alternatives/aclocal -> /usr/bin/aclocal-1.7 lrwxrwxrwx 1 root root 21 2007-06-27 21:39 /etc/alternatives/automake -> /usr/bin/automake-1.7
- In Buildroot, if you don't have configured the C++ cross-compiler yet, then:
$ make menuconfig Toolchain Options ---> [*] Build/install c++ compiler and libstdc++? [*] Build/install a shared libgcc?
Usage
- To work, Tslib needs a valid config file:
# cat /etc/ts.conf # Uncomment if you wish to use the linux input layer event interface module_raw input module pthres pmin=1 module variance delta=30 module dejitter delta=100 module linear
- and to define some ENVT variables:
export TSLIB_TSDEVICE=/dev/input/touchscreen0 export TSLIB_TSEVENTTYPE=INPUT export TSLIB_CONFFILE=/etc/ts.conf
- to create /dev/input/touchscreen0 from the infos got from:
# cat /sys/class/input/input0/mouse0/dev 13:32 # mkdir /dev/input # cd /dev/input/ # mknod touchscreen0 c 13 32 # ls -al drwxr-xr-x 2 root root 0 Jan 1 00:39 . drwxr-xr-x 5 root root 0 Jan 1 00:39 .. crw-r--r-- 1 root root 13, 32 Jan 1 00:39 touchscreen0 #
