INTRODUCTION
The CC3000-Pmod™Compatible Wi-Fi®Adapter, designed by Avnet, is a self-contained, certied 802.11b/g
Wi-Fi adapter based on the Texas Instruments SimpleLink™CC3000. Conforming to the Digilent Pmod Interface
Specication and 2 x 6 pinout, it is designed to attach to Avnet FPGA development boards that comply with the
Pmod Interface Specication. The built-in IP networking stack provides ubiquitous Wi-Fi and Internet access
without needing a complex CPU and OS. The module’s small API command set is easily incorporated into the
FPGA using a MicroBlaze microcontroller core.
This guide assumes the user has the Xilinx Spartan-6 FPGA LX9 MicroBoard hardware and has completed
verication of the MicroBoard via the “Getting Started With Spartan-6 LX9 MicroBoard Development Kit”
instructions supplied with that hardware kit and located on the Avnet Design Resource Center.
This Getting Started Guide will walk you through the procedure to install the CC3000-Pmod™Compatible
Wi-Fi®Adapter into the Spartan-6 LX9 MicroBoard and program the MicroBoard’s SPI Flash with the pre-built
embedded WiFi Webserver based demonstration that is designed to illustrate the features of the LS Research
TiWi Module, TI SimpleLink and Xilinx MicroBlaze 32-bit soft processor IP core.

If you already have the ISE Design Suite installed on computer or intend to just run this demo “standalone”,
without any development intensions, then you can proceed to the next section, “GETTING STARTED WITH THE
CC3000-PMOD™COMPATIBLE Wi-Fi ADAPTER KIT.” If you need to install ISE Design Suite, please proceed with
the instructions found in the “Getting Started With Spartan-6 LX9 MicroBoard Development Kit” located at
http://www.em.avnet.com/s6microboard.

Version 1.0 Getting Started with the CC3000-Pmod™Compatible Wi-Fi®Adapter 9
GETTING STARTED WITH THE CC3000-
PMOD™COMPATIBLE WI-FI ADAPTER KIT
As shipped from the factory, the Spartan®-6 LX9 MicroBoard’s SPI Flash is preprogrammed with an embedded
demonstration project that tests the on-board circuitry. The objective of this CC3000 WiFi PMOD Getting Started
Guide is to introduce the user to a reference design that utilizes the CC3000 WiFi PMOD of a Xilinx MicroBlaze
embedded project’s bitle, to be programmed into the MicroBoard’s SPI Flash. Then, using a terminal program,
a Wireless Access Point (WAP)/Router and a web browser, you can interact with the demo to validate the
functionality of the WiFi board.
As discussed, this reference design has been developed using the Xilinx ISE®Design Suite 13.4: Embedded
Edition software. These tools are not required for executing the procedures outlined in this getting started
guide. But users who wish to modify or investigate this design will need an EDK license (see Xilinx’s Embedded
website for licensing information: http://www.xilinx.com/tools/platform.htm EDK will be needed for rebuilding
the reference design as discussed in the “Next Steps” section of this document, where you will be introduced to
some of the details surrounding the development of the reference design.
Wi-Fi Webserver Reference Design Demo Requirements
• Computer running Windows XP or later, with an Internet browser installed.
• Wi-Fi Access Point/Router whose SSID,etc can be congured by the user.
• Avnet Spartan-6 FPGA LX9 MicroBoard
• CC3000-PMOD Wi-Fi module
• S6LX9_CC3000_PMOD_WiFi_Demo_mcs_13_4_1.zip le
• Type A male to Type A female USB extension cable and/or a +5V power supply with Type A female USB
connector (eg. cellphone charger)
• Type A to Micro-B USB cable (Optional)
Note: The LX9 MicroBoard Kit contains the two USB Cables listed above. The MicroBoard uses the Type A
male to Type A female USB extension cable to connect it to a computer USB Port or the MicroBoard could be
directly connected to a computer USB port, via P1, which is the USB to JTAG Bridge interface. The Micro-B USB
connector J3 on the MicroBoard, is a USB to UART Bridge interface that is optional for this exercise.
Note: Power can be supplied to the LX9 MicroBoard through either of the USB connectors (P1 or J3).
Re-programming the Spartan-6 FPGA LX9 MicroBoard
The LX9 MicroBoard SPI Flash is now to be programmed with the FPGA conguration and an application that
will run on the MicroBlaze Soft Core Processor of the FPGA.
1. Unzip the S6LX9_CC3000_PMOD_WiFi_Demo_mcs_13_4_1.zip le to a new folder named c:\
cc3000_test. Three les should be extracted:
• P1_USB_programming_of_CC3000_Webserver_to_LX9_Board_SPI-Flash_073112.bat
• sfutil.exe
• MM_DROP_073112.mcs

10 Getting Started with the CC3000-Pmod™Compatible Wi-Fi®Adapter Version 1.0
The results should look as follows:
Figure 1
2. Connect LX9 MicroBoard’s P1 USB connector on the LX9 board by plugging in to an available USB
port on the computer
3. From a DOS command prompt window, go to the directory where the les have been extracted to and
execute the provided .bat le to commence sfutil.exe re-programming of LX9 board’s N25Q128 serial
ash (only the rst 4MB erased/programmed) with the MM_DROP_073112.mcs Xilinx conguration le.
The results should be as shown in the following two DOS windows.
4. Once completed, remove the LX9 MicroBoard from the computer’s USB Port
Figure 2
Figure 3
The IP parameters shown in the DOS window above have been hard-coded in the project’s demo_cong.h and
cc3000.c les. Thus the Wireless Access Point/Router conguration must be edited accordingly on your WAP:
Access Point/Router SSID = xfest2012-s6lx9
AP LAN subnet IP address = 192.168.1.1

Version 1.0 Getting Started with the CC3000-Pmod™Compatible Wi-Fi®Adapter 11
An example router status after conguration is shown below.
Figure 4
Demo Setup Instructions
At this point the LX9 MicroBoard has its’ FPGA Conguration SPI Flash loaded with the Webserver conguration
and WiFi application. The WAP has been congured. All that is left is to install the WiFi PMOD, power up the
MicroBoard, let it connect to the WAP and then connect to the MicroBoards Webserver from some WiFi device.
Note: the application running on the MicroBoard has additional functionality (driving a servo motor via a the second
PMOD) that we not will not be covering in this Getting Started Guide as it requires additional PMOD Hardware.
1. Install the CC3000-Pmod™Compatible Wi-Fi®Adapter into the Spartan-6 FPGA LX9 MicroBoard’s J5
PMOD Connector. Ensure that on the WiFi PMOD, J4 is installed and J3 is set with a jumper between
pins 2-3 “Normal Mode”, as shown below.
Figure 5

12 Getting Started with the CC3000-Pmod™Compatible Wi-Fi®Adapter Version 1.0
2. (Optional Step) It is very interesting to see the timing of the of the FPGA conguration and application
bootloader results through the MicroBlaze UART, but is not required for this exercise. Details of LX9
MicroBoard related supplemental drivers, installation, etc. are discussed in the LX9 Getting Started
Guide and other related documents. The assumption here is that the user is already familiar with
MicroBoard Reference designs.
• Connect MicroBoard J3 to the computer using the Type A to Micro-B USB cable (Optional)
• Set the terminal application mapped to the USB Port connected to J3 as follows:
Figure 6
3. Connect LX9 MicroBoard P1 to a power source via Type A male to Type A female USB extension cable or
a +5V power supply with Type A female USB connector.
4. Pressing “SW4” on the MicroBoard will recongure the FPGA, then the bootloader will take over
and begin writing the application program to DDR memory. Finally the MicroBlaze will reset and the
application will run out of DDR.
a. FPGA conguration is completed when Blue LED “D1” illuminates.
b. Bootloader begins when “SREC Bootloader” is seen in terminal window (see below) and completes
when “Executing program starting at address: 00000000” is seen.
Note: Bootloader Processes (0x)00001ae2 S-records, which is the application size in S-Record ASCII Format.
c. MicroBlaze program execution (initialization of WiFi Module) is seen when Red LEDS (D2, D3, D9,
D10) begin toggling on and off for about 3 seconds.
Note: After the application has been “bootloaded” into DDR, pressing “SW5” will reset the MicroBlaze,
beginning execution at address 0, exhibiting the same ashing Red LEDS (D2, D3, D9, D10).
The following two gures show two points in time of the terminal output:
Figure 7

Version 1.0 Getting Started with the CC3000-Pmod™Compatible Wi-Fi®Adapter 13
Figure 8
5. When the LX9 MicroBoard’s Red LED “D2” goes on steady, this is an indication that it has contacted the
WAP/Router’s SSID “xfest2012-s6lx9” and is now connected.
a. If LED “D2” does not come on, attempt to:
– Reset the Microblaze application by pressing “SW5”.
– Recongure all (FPGA, DDR…) by pressing “SW4”.
6. At this point you should be able to open browser and make the connection to the webserver that is
running on the Microboard at 192.168.1.10 (http://192.168.1.10/), and the page you pull up should look
like the following:
Figure 9
a. Clicking “Dispense” should turn off LED “D2” and turn on LEDs “D9 & D10”.
b. Clicking “Reload” should turn off LEDs “D9 & D10” and turn on LEDs “D3 & D2”.
c. Alternately clicking the web page buttons will toggle the LEDs in the pairs listed.
This takes us to the end of the WiFi Webserver demonstration. For any issues with this demonstration please

whatever Internet browser is being used to access the 192.168.1.10 webpage
This string is in HTML format and it is recommended that any edits should be tested using an HTML validator
before running on the FPGA:
The essential HTML tools used in development were:
a. Online HTML Validator: http://www.onlinewebcheck.com/check.php?adv=1
b. Downloaded HTML Validator App: http://www.htmlvalidator.com/htmldownload.html
c. Online Web Design w3schools.com coaching site: http://www.w3schools.com/tags/tag_div.asp

Version 1.0 Getting Started with the CC3000-Pmod™Compatible Wi-Fi®Adapter 15
Select the applicable HTML tag and then use the “Try it yourself >>” button
Note: Before checking the HTML string in one of these validators you need to strip-out all the “\” backslash
characters (search & replace)
webserver.c
line# 245-261 toggleLEDFunc() is where the LEDs and Servo are activated.
line 252 and 258 to make changes to the servo rotation range
As discussed earlier, below is a diagram of the existing demonstration which is the “Spartan-6 LX9 Internet
Appliance Demo” shown at 2012 X-fests. “Plan B” is only needed if hardwired ethernet is desired. A full
description, including the hardware requirements of this full application will be place on the Avnet DRC at
http://www.em.avnet.com/pmodwi
Figure 10
Note: With the WiFi module on the LX9 MicroBoard an additional load is now added to the USB supply of a typical
PC. If you seem to be having power problems, try powering the board via both connectors as the demonstration
runs or consider a separate USB Hub, as many PCs do not provide enough power through a single USB Port.
Note: It is not possible to connect to the WiFi_Pmod in ad hoc mode, an Access Point/Router is always required!
