Key Event Problems

[obigose]

H/W:

Freescale i.MX6

• Base Board: MCIMXABASEV1
• CPU Cards: MCIMX6QAICPU1 (Cortex -A9, 1.2Ghz Quad core)
• Display: MCIMX-LVDS1 (10.1 1024 x 768 XGA display with capacitive multi-touch)

BSP:

Linaro Ubuntu 11.10

Questions:

1.     We are trying to implement applications which makes use of longpress events. However, our tests show that down-key event and up-key events are generated simultaneously when key is released. The system must send us down-key event upon touch and up-event upon release in order for us to implement long-press. Is there a way to do this?

2.     We are trying to generate system tone (beep) upon key-press. The reason for wanting to use the system-level tone is for performance reasons. We don’t want to have to play a media file every time upon touch. Is there a way to use system tones?

About Q#1:

Imx6 reference  design boards use eGalax touch screen on LVDS panel for touch test,  we cannot find such issue.

Pls make sure which touch screen does they use? And pls they use “evtest” tool to validate it.

Event “EV_ABS” must report after touch screen interrupt generation.

About Q#2:

For touch sound, it must be handled in Application layer, not system level.

Thanks,

Andy

About Q#1

This image is the back of our touch screen device information.

We think that we use HannStar, not eGalax.

This URL is our main issue reproduction step video.

Touch-screen events are not fired on Ubuntu's X system - YouTube

In the video,

above terminal is "evtest" tool.

below terminal is "xev" tool.

The video shows that "evtest" tool well gets touch-press event when we touch down, unlikely "xev" tool does not.

"xev" test terninal is updated when we touch up with touch-press event.

By these tests - "evtest" and "xev", we suppose that touch-press event is well fired by device driver, but not transferred to Ubuntu's X system.

Question:

Do you know how to fix it??

[DuanFugang]

Pls try below steps for ubuntu， thx.

=========Config touch screen on Ubuntu=========

1.Download a evtouch debian package from ,it is a Touchscreen-Driver for X:

http://wiki.freescale.net/download/attachments/29493146/xserver-xorg-input-evtouch_0.8.8-3build1_arm...

2.Run "dpkg -i xserver-xorg-input-evtouch_0.8.8-3build1_armel.deb" to install debian package.

3.Do some configAdd below two sections in /etc/X11/xorg.conf

Section "InputDevice"

Identifier "touchscreen"

Driver "evtouch"

Option "Device" "/dev/input/event2"

Option "DeviceName" "touchscreen"

Option "MinX" "0"

Option "MinY" "0"

Option "MaxX" "4352"

Option "MaxY" "3200"

Option "ReportingMode" "Raw"

Option "Emulate3Buttons" "false"

Option "Emulate3Timeout" "50"

Option "SendCoreEvents" "On"

EndSection

Note: You should check /var/log/Xorg.0.log and search "P1003" to get right /dev/input path. Then modify "Option Device" (shown as red color) as right path.

4.Change the "ServerLayout" Section to below:

Section "ServerLayout"

Identifier "Default Layout"

Screen "Default Screen"

InputDevice "touchscreen"

EndSection

5.Run "sudo service gdm restart" to restart X server.

=========Test touch screen on Ubuntu=========

6.Now you can operation on ubuntu desktop with finger

Or test event in console:

# stop gdm

# export http_proxy=xxxxx

# apt-get install evtest

# evtest /dev/input/eventX (which depends on the touch screen event handler)

Thanks for your answer, but it still does not work.

1.Download a evtouch debian package from ,it is a Touchscreen-Driver for X:

http://wiki.freescale.net/download/attachments/29493146/xserver-xorg-input-evtouch_0.8.8-3build1_arm...

=> The URL is not available, so I used this URL - 0.8.8-3build1 : xserver-xorg-input-evtouch : armel : Lucid (10.04) : Ubuntu

2.Run "dpkg -i xserver-xorg-input-evtouch_0.8.8-3build1_armel.deb" to install debian package.

=> When I install xserver-xorg-input-evtouch_0.8.8-3build1_armel.deb, I met some dependecy errors.

Without Step2's installation, I tried to change /etc/X11/xorg.conf like Step3, Step4, Step5(We use lightdm).

This is not still working.

Please give me some more information.

Attach fsl xserver-xorg-input-evtouch_0.8.8-3build1_armel.deb

Please have another try.

Hi, AdaLu

Thanks for your information.

However, error message is the same. I can not install new driver file that you attached.

Error message is below.

Do you have another idea??

[ada_lu · Accepted solution]

All of your logs show this deb package is not install properly.

dpkg: error processing xserver-xorg-input-evtouch (--install):

Please remove old deb package and make sure to install xserver-xorg-input-evtouch_0.8.8-3build1_armel.deb successfully first, then the touch will be effective on ubuntu desktop.

[ada_lu]

Please do this configuration based on freescale standard ubuntu release, not your customized rootfs to isolated this issue.

About Q#2

Generally, Linux and window PC have system beep sound.

when Linux and Window PC is starting, use system beep sound.

Below code is the code which is using system beep sound.

/* test_beep */

void ApplicationIm::beep() {

    int freq = 440;

    int len = 5000;

    int fd = open("/dev/console", O_WRONLY);

    ioctl(fd, KDMKTONE, (len<<16)+(1193180/freq));

    close(fd);

}

Is there any solution getting system beep? not using media player....
