Touch not response

Hello,

You could check you Linux environment, also check the exports that your /etc/init.d/matrix-gui-e does; you should have something like export TSLIB_TSDEVICE="/dev/input/event0" export QWS_MOUSE_PROTO="Tslib:/dev/input/event0" for LCD, when you are starting the matrix-gui. If something else or none is exported, that could cause that problem.

Hi Vladimir

Thanks for reply.

I am sure the TSLIB_TSDEVICE and QWS_MOUSE_PROTO was exported.

However the touch not response.

If I run then matrix demo manually, the touch response well.

Does anyone encounter this issue?

Hello,

Yes, but matrix-gui-e is a script, these exports will not affect it like this. It is important what is exported in the script itself.

Please, check this with:

cat /etc/init.d/matrix-gui-e

Hi Vladimir

Thanks for reply.

When I click the the LCD pannel, I can see the mouse cursor at cerrect position. But matrix demo not response.

I notice that have two lines difference between the matrix-gui-e script and the press "set" in the console terminal.

1. press "set" in the console terminal

QWS_MOUSE_PROTO='Tslib:/dev/input/touchscreen0'

TSLIB_TSDEVICE='/dev/input/touchscreen0'

2. in the matrix-gui-e script file

export TSLIB_TSDEVICE=/dev/input/event0
export QWS_MOUSE_PROTO="Tslib:/dev/input/event0 Auto:/dev/input/mice"

Is this difference cause the result?

following is my matrix-gui-e script file contents.

root@dm814x-evm:~# cat /etc/init.d/matrix-gui-e
#! /bin/sh

matrixgui="/usr/bin/matrix_guiE"
GUI_OPTS="-qws /usr/share/matrix/html/menu_main.html"
PIDFILE="/var/run/matrix-gui-e.pid"

test -x "$matrixgui" || exit 0

export TSLIB_TSDEVICE=/dev/input/event0
export QWS_MOUSE_PROTO="Tslib:/dev/input/event0 Auto:/dev/input/mice"

calibrate()
{
if [ ! -f /etc/pointercal ] ; then
echo -n "Calibrating touchscreen (first time only)"
ts_calibrate
echo "."
fi
}

case "$1" in
start)
calibrate

if [ -e $PIDFILE ]; then
PIDDIR=/proc/$(cat $PIDFILE)
if [ -d ${PIDDIR} -a "$(readlink -f ${PIDDIR}/exe)" = "${matrixgui}" ]; then
echo "$DESC already started; not starting."
else
echo "Removing stale PID file $PIDFILE."
rm -f $PIDFILE
fi
fi

echo -n "Starting Matrix GUI application"
start-stop-daemon --start --quiet --background --exec $matrixgui -- $GUI_OPTS
pidof matrix_guiE > $PIDFILE
echo "."
;;

stop)
echo -n "Stopping Matrix GUI application"
start-stop-daemon --stop --quiet --exec $matrixgui
echo "."
;;
*)
echo "Usage: /etc/init.d/matrix-gui-e {start|stop}"
exit 1
esac

exit 0

Hello,

Did you managed to solve this issue?

Normally /dev/input/touchscreen0 is a soft link to /dev/input/event0, but could be to another event in your case. On your side what is the output of ls -l /dev/input/ ?

HI Vladimir

This issue was solved.

I changed the matrix-gui-e script file below and then found the demo work well.

export TSLIB_TSDEVICE=/dev/input/event0
export QWS_MOUSE_PROTO="Tslib:/dev/input/event0"

Hello Xu Steven,

I am glad that the issue is solved. Thank you very much for the feedback.
