Hi

I have a problem with the tslib and sdl. The SDL_MOUSE.. event gives starnge coordinates. When I press on the screen the mouse cursor jumps to random positions.

I tested the Touchscreen with ts_test and it works fine. So the problem is just with the SDL.

=================================================

Toolchain: 2010RC4

uclinux-dist: 2010RC4

Board: BF548-EZKIT

----------------------------------------------------

env:

#SDL

export SDL_NOMOUSE=1

export SDL_MOUSEDEV=/dev/event1

export SDL_MOUSEDRV=TSLIB

#Touchscreen

export TSLIB_TSEVENTTYPE=INPUT

export TSLIB_FBDEVICE=/dev/fb0

export TSLIB_CONSOLEDEVICE=none

export TSLIB_CONFFILE=/etc/ts.conf

export TSLIB_CALIBFILE=/mnt/pointercal

export TSLIB_TSDEVICE=/dev/event1

export TSLIB_PLUGINDIR=/usr/lib/ts

----------------------------------------------------

ts.conf:

module pthres pmin=1

module variance delta=30

module dejitter delta=100

module linear

Ok, I got it.

I changed the Makefile from the SDL (uclinux-dist/lib/libsdl/Makefile):

CONF_OPTS = \

      --disable-arts \

      --disable-esd \

      --disable-pth \

      --disable-video-directfb \

      --disable-video-x11 \

      --enable-input-tslib

Now it works fine.
