qt embedded mouse problem

Hi Rodrigo,

It sounds like you have done everything right.  Please double check on this page and let me know if you still are having problems:

http://processors.wiki.ti.com/index.php/How_to_use_a_Mouse_instead_of_the_Touchscreen_with_Matrix

The default kernel configuration will not work, you actually have to change the mouse settings.

You can ignore the last step "Cursor Enable", that has been changed in the matrix_gui source to always have the mouse enabled.

Hi Jeff,

Thanks for your response.  But I again checked the kernel, the Mouse Interface and Mice were enabled.  I also rebuilt the kernel and when changing the QWS_MOUSE_PROTO to mice it still did not work.

I ran the following commands to check the kernel as well as build it:

- cd to ti-sdk-am3517-evm-4.0.1.0/psp/linux-2.6.32-psp03.00.01.06.sdk

- make menuconfig and made sure Mouse Interface and Mice were enabled

- make CROSS_COMPILE=arm-none-linux-gnueabi- ARCH=arm am3517_evm_defconfig

- make CROSS_COMPILE=arm-none-linux-gnueabi- ARCH=arm uImage

I copied the uImage file to my tftboot directory and restarted the board.  Once the environment variables had changed i ran my application and the mouse still didn't work.

This are my environment variables :

TSLIB_TSDEVICE=/dev/input/touchscreen0 MAIL=/var/mail/root OLDPWD=/home/root HOME=/home/root PS1=\u@\h:\w\$ LOGNAME=root TERM=linux PATH=/usr/local/bin:/usr/bin:/bin:/usr/local/sbin:/usr/sbin:/sbin SHELL=/bin/sh PWD=/home/root/tooltips2_board_2 TZ=UTC QWS_MOUSE_PROTO=Auto:/dev/input/mice EDITOR=/bin/vi

Is there something I need to do to my QT code for this to work?  Or is my environment not set properly?

Thanks,

Rodrigo

Rodrigo,

I can only think of two things that may be keeping the mouse from working.

1. The Host USB on the AM3517 is High Speed (HS) only.  Are you using a powered HS hub inbetween your EVM and your mouse.  The mouse plugged directly in to the USB Host connector will not work without a Hub. A HS Hub will allow the Low Speed (LS) mouse to work. 

2. According to the SDK version you specified, the Matrix Gui project in your SDK should have the Cursor enabled, but you can check:

/home/user//ti-sdk-am3517-evm-4.0.1.0/example-applications/matrix-gui-e-1.3/main.cpp 

and verify the following code is commented out:

//Commented out to enable the mouse

//    QApplication::setOverrideCursor(QCursor(Qt::BlankCursor));

Hi Jeff,

I have a 2.0 usb hub which i believe is High Speed.  

I also looked at the file you mentioned and that line is commented out.

This is what is located within my input folder

ls /dev/input/

by-id         event0        event2        touchscreen0

by-path       event1        event3

Does that look right?  also when I do a cat /dev/input/event3 and move the mouse i can see activity on the screen, don't know if that gives any information.

The closest I saw to a mouse movement was when i did export QWS_MOUSE_PROTO=LinuxTP:/dev/input/event3  When i moved the mouse the cursor disappeared.  Any ideas how i can make this work?

Thanks,

Rodrigo

Jeff,

For some reason mine is different, I went in the menuconfig within ti-sdk-am3517-evm-4.0.1.0/psp/linux-2.6.32-psp03.00.01.06.sdk which is the same 2.6.32 that you are  using.

Can you tell me what configurations you see when doing a make menuconfig?  

Is there something more than just mouse interface and mice i have to enable?  

Is there something i need to disable?  

Is the way I made my uImage in the second post correct?

Thanks,

Rodrigo
