PenMount DMC9000 rs232 touchscreen Qt/E 4.5

[mquinteiro]

Hi,

I'm trying to do my fist toy with Qt/E. The plataform is:

IEI AFL-07A-LX
framebuffer lxgx
kernel 2.6.29.1
Qt/E 4.5.0
and .... DMC9000 Penmount touchscreen.

It's a rs232 touch screen who works in /dev/ttyS3

with minicom I can read data in response to screen events.

with penmount snifer It's work

root@afolux:~/pmlinux-ubuntu8.10# ./pm-sniff /dev/ttyS3
+---------------------------------------------------------------+
| pmsniff - PenMount sniffer (build:Nov 13 2007 14:33:21) |
+---------------------------------------------------------------+
Port : /dev/ttyS3
Baud : 19200 bps
PenMount 9000 found!
1 : bf 03 27 05 4a ( 423, 714) Up
2 : ff 03 27 05 4a ( 423, 714) Down
....

But I can't make work together with my application

I have do:
export QWS_MOUSE_PROTO=IntelliMouse:/dev/ttyS3
export QWS_MOUSE_PROTO=MouseMan:/dev/ttyS3
export QWS_MOUSE_PROTO=Microsoft:/dev/ttyS3

but... nothing (now I'm building QT with tslib support bun I'm not so confident)

Please help!

If you are using a touchscreen then try the touchscreen driver

[mquinteiro]

If you are using a touchscreen then try the touchscreen driver

I try........

if I use:

# export QWS_MOUSE_PROTO=linuxTP:/dev/ttyS3

# myapp -qws

I get:
Could not read calibration: "/etc/pointercal"

and if screen is pressed the cursos goes.....

I've try

# ts_test
/dev/touchscreen/ucb1x00: No such file or directory

and...

# ts_calibrate
ts_open: No such file or directory


with:
# export QWS_MOUSE_PROTO=tslib:/dev/ttyS3
# myapp -qws
Does nothing.

another clue?

As far as I remember QtEmbedded docs contain instructions on how to debug your input device step by step. Try finding it and see where it leads you. My experience with embedded is very limited so I'm unable to help you with such details. You have to make your device work with tslib if you want to use it with Qt or you can implement your own input plugin if you can determine what events are sent from the device (seems a bit similar to what you posted at the beginning of this thread).

I didn't found it, but "We can"

I think you are right, ts_test do not work properly, my first approach will be make tslib and utils work.

or you can implement your own input plugin if you can determine what events are sent from the device (seems a bit similar to what you posted at the beginning of this thread).

I have found this link http://lists.trolltech.com/qt-embedd...ad00000-0.html and it looks like your second approach.

I have read Lots of questions about this ts and no answer, I will write here if I get some solution.
