MAX11800/MAX11801 Touch
Evaluation Systems (TEVS)
General Description
The MAX11800/MAX11801 touch evaluation sys-
tems (TEVSs) demonstrate the rich feature set of the
MAX11800–MAX11803 family of touch-screen controllers
(TSCs) and allow for their evaluation. Each TEVS consists of a
USB interface board (UTIB+), a MAX11800/MAX11801
evaluation kit (EV kit) daughter board, and a 4-wire touch
sensor (USB cable included).
Note:
The MAX11802
and MAX11803 are subsets of the MAX11800 and
MAX11801, respectively.
Order the MAX11800 TEVS for a comprehensive
evaluation of the SPI™-compatible TSCs using a PC.
Order the MAX11801 TEVS for a comprehensive evalua-
tion of the I
2
C-compatible TSCs.
The TSCs provide a complete resistive touch-screen
controller solution that targets touch-enabled devices
with small- to medium-size displays. The TSCs enable
miniaturization of consumer products due to their ultra-
small size. Their low power consumption makes them
attractive for portable devices.
Each TEVS operates directly from the USB power.
Windows XP
M
- or Windows
M
7-compatible software
running on a PC interfaces to the TEVS board through
the computer’s USB communications port. See the
Quick
Start
section for setup and operating instructions.
The EV kit provides a proven PCB to facilitate evaluation
of the TSCs directly by the user. It must be interfaced to
the appropriate SPI/I
2
C timing signals for proper opera-
tion. See Figures 12a, 12b, and 13 for connections and
appropriate voltage levels. Refer to the MAX11800–
MAX11803 IC data sheet for timing requirements and
register addresses.

DESCRIPTION
Software and driver CD-ROM.
EV kit (with the TSCs mounted on it, but can be
separated from the TEVS for evaluation of the
TSCs in the user setup).
USB interface board (UTIB+). This acts as a
gateway converting and accepting data from
the USB port to SPI/I
2
C for the EV kit. The EV kit
plugs into the UTIB+.
USB cable for power and communication.

Note:
In the following sections, software-related items
are identified by bolding. Text in
bold
refers to items
directly from the EV kit software. Text in
bold_and_under-
lined
refers to items from the Windows operating system.
4)
The driver for the EV kit is installed in the following
location:
C:\CMAXQUSB
or
C:\MAXIM TSC USB DRIVER CDM20602 (for
newer drivers)
1)
Before plugging the TEVS into an available port on
a Windows XP- or Windows 7-compatible PC, the
TEVS software must be installed.
Procedure (TEVS Software and
USB Driver Installation)
5)
The application along with its supporting files is
located at:
C:\Program Files\Maxim Integrated Products\
MAX118xx EVS <version>
2)
The software comes with the USB driver and a GUI
application. Unzip the files and put the contents in
an easily accessible location.
Locate the Setup.exe and double-click on it and
follow the instructions for installation.
6)
3)
A short cut to the application executable file is cre-
ated on the desktop and in the
Start_ |_ Programs
menu.
To uninstall the software, go to
My_Computer_|_Add_
or_Remove
program.
