MAX11800/MAX11801 Touch  
Evaluation Systems (TEVS)  
General Description  
Features  
The MAX11800/MAX11801 touch evaluation sys-  
tems (TEVSs) demonstrate the rich feature set of the  
MAX11800–MAX11803 family of touch-screen controllers  
(TSCs)andallowfortheirevaluation.EachTEVSconsistsofa  
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.

Software  
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.

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/I2C 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.

Quick Start  
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.  
C:\CMAXQUSB  
or  
C:\MAXIM TSC USB DRIVER CDM20602 (for  
newer drivers)  
Procedure (TEVS Software and  
USB Driver Installation)  
1) Before plugging the TEVS into an available port on  
a Windows XP- or Windows 7-compatible PC, the  
TEVS software must be installed.  
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.  
6) A short cut to the application executable file is cre-  
ated on the desktop and in the Start_ |_ Programs  
menu.  
3) Locate the Setup.exe and double-click on it and  
follow the instructions for installation.  
7) To uninstall the software, go to My_Computer_|_Add_  
or_Remove program.

Detailed Description of Hardware  
Ensure that the MAX11800/MAX11801 EV kit daughter  
board is properly mounted on the UTIB+ and the touch-  
screen panel is properly connected to the daughter  
board. The daughter board houses the TSC IC. This  
module processes the data from the touch-screen panel  
connected to it and streams it out to the UTIB+ interface  
board.

Hardware Installation  
Note: Install the software before starting this step.  
Connect the TEVS to the PC using the USB cable  
provided. A dialog box appears, as shown in Figure 3.  
The UTIB+ acts as an intermediary gateway that con-  
verts the SPI/I2C (signal levels and protocol) into the  
USB for processing by the PC. The UTIB+ includes a  
MAXQ2000 microcontroller to carry out this task.  
Click on the Install_ from_ a_ list_ or_ specific_ location_  
(Advanced)_ radio button and then press the Next_  
button.  
For the MAX11800TEVS+, the jumpers on the UTIB+  
should be in the following positions:  
Type C:\CMAXQUSB in the edit box, as shown in Figure  
4, or press the Browse button to find the CMAXQUSB  
driver folder. Press the Next button to proceed. For the  
new driver, change CMAXQUSB_ to_ MAXIM_ TSC_ USB_  
DRIVER_CDM20602.

During the installation steps, the warning shown in Figure  
5 is displayed. Press the Continue_ Anyway button to  
proceed.  
the MAX11800–MAX11803 IC data sheet for details on  
the registers.  
Upon startup, factory-default values from the MAX11800-  
01_init.ini files are loaded onto the GUI and then written  
into the MAX11800/MAX11801 TSC.  
Follow the remaining steps that come up and exit when  
done. At the end of the process, the driver is installed  
and the device is ready to be used. Disconnect and plug  
the device back in again.  
The user can change the factory-default values in the  
MAX11800-01_init.ini file and enter new values on the  
GUI, by selecting the File_|_Save option from the menu  
bar. This overwrites the factory-default values in the  
MAX11800-01_init.ini file. The user also has the option  
to save the register values on the GUI screen under a  
different name by selecting the File_|_Save_As_option, or  
open and load a previously saved file by selecting the  
File_|_Open_and_Load option.  
MAX11800/MAX11801 TEVS  
GUI Description  
Note: The MAX11802 and MAX11803 are subsets  
of the MAX11800 and MAX11801, respectively, and  
operate only in direct conversion mode. After the  
successful installation of the driver, connect the  
MAX11800/MAX11801 TEVS to the PC using the USB  
cable. Start the GUI by double-clicking on the MAX118xx_  
EVS_<version>.exe file. The GUI can also be selected  
from the Windows Start menu.  
The GUI automatically writes to the MAX11800/MAX11801  
TSC when a new .ini file is opened and loaded. However,  
when the user individually manipulates bits on the  
GUI screen, it must be followed by pressing the Write_  
Registers button. The Read_ Registers button reads  
all the registers from the TSC and displays them in the  
binary and hex fields.  
The GUI searches for the device and after a successful  
USB communication link displays USB_comm._success-  
ful in the right-hand side of the status bar. If the GUI fails  
to establish a communication link, USB_comm._failure  
is displayed.  
At any given time, the computer mouse can be scrolled  
over a checkbox (the bit indicators) and the status with a  
description is indicated by the tool tip.  
Following a successful USB communication link, the GUI  
pings the TSC (MAX11800/MAX11801) and establishes  
a link with the device and displays the following on the  
GUI window.  
Note: Any changes on the GUI must be followed by  
pressing the Write_Registers button for the value to be  
loaded into the MAX11800/MAX11801 TSC.  
1) Window caption:  
Touch Data Tab  
The Touch_Data tab displays the user inputs in the touch  
panel on the screen. The user can make various selec-  
tions to display a combination of X, Y, Z1, and Z2 data  
along with their processed/mathematical interpretation.  
For the MAX118xx: MAX118xx_ 4-wire_ Advanced_  
Touch_Screen_Controller, where xx = 00, 01  
2) Left side of status bar:  
For the MAX11800: TSC_ Communication:_ SPI_  
TSC_device_found  
The MAX11800 and MAX11801 TSCs have two modes  
of operation: direct conversion and autonomous conver-  
sion. Refer to the MAX11800–MAX11803 IC data sheet  
for more details. The MAX11802 and MAX11803 only  
support direct mode.  
For the MAX11801: TSC_ Communication:_ I2C_  
TSC_device_found  
If the MAX11802 or MAX11803 are to be evaluated,  
select the appropriate device under the Manual_Search  
menu item. The right side of the status bar then displays  
USB_communication_successful.  
Direct_Conversion_Mode: Direct conversion mode can  
be selected either in the Registers tab by selecting it  
in the Operating_ Mode_ Configuration register or by  
selecting it in the Touch_Data tab, as shown in Figure 7.  
Registers Tab  
The Registers tab shown in Figure 6 displays a success-  
ful communication link with the MAX11800 device. The  
ensuing discussion applies to all MAX118xx devices.  
This tab displays the registers related to X, Y, Z1, and Z2  
measurements of the MAX118xx. The user can manipu-  
late the register values by changing the binary bit pat-  
terns on the right or the hex values on the left. Refer to  
Autonomous_ Conversion_ Mode: Autonomous con-  
version mode can be selected in the Registers tab  
by selecting it in the Operating_ Mode_ Configuration  
register, or by selecting it in the Touch_ Data tab, as  
shown in Figure 8.

Raw Data  
Multi-Touch Tab  
The Raw_Data tab (Figure 9) displays a stream of raw  
data that gets collected during the operation of the TSC.  
This data can be saved by pressing the Save_ Data  
button for data analysis.  
The Multi-Touch tab (Figures 10 and 11) gives a simple  
demo of the multi-touch on a resistive panel. Use the  
touch panel to enlarge and reduce the picture found  
in this tab. This works only in the autonomous mode.  
Contact the factory for details on this feature.
