: Great news for all those trying to get their
: touchscreens to work on the Assabet!
OK - So we have it confirmed, that using the instructions
below for the kernel mods, and then using the
IPAQMOUSE=Y and /dev/3600_ts (11,0)
that Microwindows runs on the Assabet with touch
screen support. Correct?
Regards,
Greg
:
: With some help from Roman Jordan (from the
: handhelds.org mailing list, I think) my touchscreen is
: finally working! Well I wouldn't say it's perfect but
: it sure is close!
:
: It's quite a minor change actually.
: 1. Open the file drivers/char/ucb1200_ts.c
:
: 2. You'll find x_rev = 0 (If I remember correctly it's
:
: in line 190...just search for it in case I'm wrong)
:
: 3. Change x_rev AND y_rev both to 1.
:
: 4. Recompile the kernel...and enjoy the Microwindows
: minesweeper game!
:
: Ok...now to point out some of the minor hiccups.
:
: 1. The area close around the centre of the screen
: works perfectly.
:
: 2. However, if you press a point close to the left and
: right edges of the touchscreen (I'm referring to the
: landscape format), the point activated is around 0.5cm
: away (towards the centre of the screen) from the point
: where the pressure is applied.
:
: Hope all this is useful for those trying to get their
: Assabet touchscreens running.
:
: Have fun!
