TOUCHES
TOUCHES.EXE allows you to confirm that ELODEV is communicating properly
with the controller and to check touchscreen linearity.
To run TOUCHES, type the following at the DOS prompt:
TOUCHES [Enter]
Touch the screen and the program will display the X and Y coordinates of your
touch, the Z value if the controller determines one, and a single "TRUE" only
when you lift your finger (untouch). The coordinates should stream as described
under the discussions of COMDUMP and BUSSTAT. Press any key to quit.
If TOUCHES does not display any data, but COMDUMP or BUSSTAT works,
your ELODEV command line is incorrect, or you have an interrupt contention
with another device.
If TOUCHES does not display coordinates at a steady rate with serial controllers,
the baud rate may be incorrect. Check the ELODEV command line and
Appendix A.
If TOUCHES does not display coordinates at a steady rate with IntelliTouch
controllers, see the IntelliTouch Product Manual for hardware troubleshooting
steps, or contact Elo Technical Support.
If TOUCHES indicates "TRUE", or a series of "TRUE"/"FALSE" when you have
not lifted your finger, try increasing the Untouch Wait Time with the -w flag as a
temporary solution (see page 32). Contact Elo Technical Support.
TOUCHES can also be used to perform a linearity check of the touchscreen.
(BUSSTAT can also perform this check with bus controllers). If TOUCHES is
run without calibrating ELODEV, TOUCHES will display the untranslated (raw)
coordinates of your touch. Make sure ELODEV is loaded without the -c
calibration flag and without running ELOCALIB. From the coordinate display,
you can determine which corner is the origin and watch both X and Y increase
steadily as you slide your finger to the diagonally opposite corner. Check the other
two corners to make sure their coordinates look correct and the touchscreen
appears linear in each axis.
