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:
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.)
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.
Thanks!
Regards,
Frederico
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:
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
