RS-232 Specific Information
Port Assignment
The driver loads based on the "Port" value entry within the "TSHARCS.reg" file. This value
corresponds with the available port.
Baud Rate Configurations
If using a TSHARC® controller using other than a 9600 baud rate, the baud rate may be changed
via the “Baud” registry entry. This may also be found in the “TSHARCS.REG” file.
TSHARC controllers are 9600 Baud by default.
PS/2 Specific Information
The 8042 input driver must be included in the OS Design in order for the TSHARC PS/2 driver to
function on CE device.
USB Specific Information
The USB host controller and the UHCI component must be installed in order for USB to function.
These components are added automatically after adding the "USB TSHARC Touch Screen
Driver" component to the OS Design.

Platform Builder 4.2 must already be installed and configured on your Windows
development system.
Please be sure no instances of Platform Builder 4.2 are currently running.
Navigate your system to find the TSHARCCE42V118.MSI executable file.
"Port"=dword: 1” assigns the port to the first available port defined in the “platform.reg”
file.
"Port" ="dword: 2" assigns the port to the second available port defined in the
“platform.reg” file.
