Hi, can you explain me how did you manage to make the tslib work ? because I've done the samething :
sudo apt-get install libts-bin /etc/ts.conf contains module_raw input module pthres pmin=1 module variance delta=30 module dejitter delta=100 module linear export TSLIB_CONSOLEDEVICE=none export TSLIB_CONFFILE=/etc/ts.conf export TSLIB_CALIBFILE=/etc/pointercal export TSLIB_TSDEVICE=/dev/input/event1 export TSLIB_FBDEVICE=/dev/fb0 #export TSLIB_PLUGINDIR=/usr/lib/ts export TSLIB_PLUGINDIR=/usr/lib/arm-linux-gnueabihf/ts0 export TSLIB_TSEVENTTYPE=INPUT debian@arm:~$ sudo ts_calibrate*ts_open: No such file or directory* On Wed, Feb 19, 2014 at 7:54 PM, brian larochelle < [email protected]> wrote: > Summary: After a successful ts_calibration and ts_test, ts_test shows > varying results after reboots. > > I am connecting a beaglebone black to a 16 bpp, 4 wire touchscreen/LCD. > The lcd is working beautifully, but I am having an issue with the > touchscreen.
