Beagleboard and touch screens

Hello everyone. I’m looking into using the Beagleboard xm with a touchscreen and the Froyo setup from TI (rowboat project).
I’ve been looking into possible touchscreen options and would like to know if you have had good experiences working with touchscreens.
I would like to start with some easy option, almost plug & play functionality. I’m considering this option:

Lilliput 7" 669gl-70np/c/t

I’ve found out that it has some issues:

But maybe they have been ironed out. Any comments? Alternatives? I’m looking to spend $250 tops on this.

Also, I would like to ask if someone has made some work with some more elaborate options and connections to the beagleboard (using some custom touch controllers, developing drivers, etc.)

Thank you in advance for your help!


Hello Ismael,

Lilliput 7" 669gl-70np/c/t…

I have taken a look at the option above and it seems to be very easy.
According to the following website:
There is a video input as HDMI and there is no touch screen input. So,
I understand that it would use the HDMI input for the touch screen as
well. I just do not know how that would be set in Beagle board. But
the screen should work instantaneously if you use a HDMI-HDMI cable.
I would appreciate if you share your decision and experience here.

No. Your link is for 669GL-70NP/C, but only Lilliput 669GL-70NP/C/T has TS inputs.

The text above was taken from:

"Video inputs HDMI, DVI, VGA, composite"
"Touch screen inputs None"

and this one was taken from the following website under specification:

Of course, there was no connection, that was the model 669GL-70NP/C.
So, that is the model without touch screen.

Hello Ismael,
I have bought recently a 7" Faytech monitor with touchscreen and a lot
of different input plugs like HDMI, S-Video, VGA, USB, etc.
I have not been using touch screen but it was easier to make the
screen to work than the 7" Lilliput. So, I am sending you a link and
you have an extra option:;ACTION=3;LA=444;GROUP=E310;GROUPID=4649;ARTICLE=87444;START=0;SORT=artnr;OFFSET=76;SID=28FbfFtqwQARwAABK2JvEf0c4ad6bc1f79af1e4e89a86038e981b

For S-video which is the one I am using, you have to edit the
following boot.cmd line (with nano or vi):
setenv bootargs 'console=ttyS2,115200n8 omapdss.def_disp=tv
omapfb.mode=640x480@60 root=/dev/mmcblk0p2 rw rootwait'

Adding this (for example):
omapdss.def_disp=tv omapfb.mode=640x480@60

After saving the boot.cmd you entered this command:
mkimage -A arm -O linux -T script -C none -a 0 -e 0 -n "Ubuntu 10.10" -
d ./boot.cmd ./boot.scr

Then, reboot and it should work.

Hi freddyglima,

Were you able to get touch screen input working for the 7" Faytech monitor that you bought. Which version of BB are you using, which OS ?
