TouchWare for Windows NT User's Guide124
Problem: Lines are not straight and smooth. Drawings are jagged.
The problem could be one of the following:
You need to adjust the frequency level of the controller. Run
Microcal and use the Noise Check command to change the
frequency level. For more information on adjusting the
controller’s frequency level, refer to Chapter 4.
You need to increase the Sample Rate setting. Use the Advanced
Settings dialog box in the Touchscreen Control program to
increase the Sample Rate. For more information, refer to
Chapter 2.
Problem: Touchscreen driver does not load.
May be one of the following problems:
You specified the wrong communication settings during
installation. Use Microcal to check the touchscreen controller’s
COM port, baud rate, and IRQ. Use the Hardware Controls
dialog box in the Touchscreen Control program to modify the
communication settings used by the touchscreen driver so that they
match those of the controller. If you are using Custom
communication settings, be sure that the base address is correct.
After changing the communication settings, reboot the system.
For more information on Microcal, refer to Chapter 4. For more
information on the Touchscreen Control program, refer to
Chapter 2.
Another driver is using the same COM port, IRQ, or base address
as the touchscreen controller and driver. Use Microcal to specify
unique communication settings for the touchscreen controller. Use
the Hardware Controls dialog box in the Touchscreen Control
program to modify the communication settings used by the
touchscreen driver so that they match those of the controller. If
you are using Custom communication settings, be sure that the
base address is correct.
After changing the communication settings, reboot the system.
