Preface

This guide is intended to assist users in the initial setup and demonstration of running their first sample

application for the CC3220, CC3220S, and CC3220SF SimpleLink™ Wi-Fi®and Internet of Things

Solution, a Single-Chip Wireless MCU from Texas Instruments™. The guide explains how to install the

software development kit (SDK) and various other tools required to get started with the first application.

Introduction

This preliminary release of the Getting Started guide is focused on the Code Composer Studio™ (CCS)

IDE.

For detailed IAR instructions, refer to:

<sdk-installation-path>\docs\cc3220\CC3220_SDK_IAR_project_setup_guide.html

GCC is currently not supported.

The CC3220 device is part of the SimpleLink microcontroller (MCU) platform, which consists of Wi-Fi,

Bluetooth®low energy, Sub-1 GHz, and host MCUs. All share a common, easy-to-use development

environment with a single core software development kit (SDK) and rich tool set. A one-time integration of

the SimpleLink platform lets you add any combination of devices from the portfolio into your design. The

ultimate goal of the SimpleLink platform is to achieve 100 percent code reuse when your design

requirements change. For more information, visit www.ti.com/simplelink.

Prerequisites

The user is expected to have the following:

• CC3220S-LAUNCHXL or CC3220SF-LAUNCHXL

• An 802.11b/g/n (2.4-GHz) Wireless Access Point (AP)

• A computer running Microsoft®Windows 7

Download and Installation

Chapter 1

SWRU461B–February 2017–Revised June 2018

Download and Installation

1.1 CC3220 Software Development Kit (SDK)

• Download the following software at CC3220 SDK package.

• Run the installer by double-clicking on the CC3220 SDK installer.

• Read and accept the license agreement to proceed.

• Choose the desired path to place the package (else default is chosen).

• Proceed with the installation and click Finish once done.

1.2 Service Pack

If the board is not already flashed with the service pack for SDK <version>, the latest service pack for

SDK <version> must be flashed on the CC3220 wireless MCU. The most updated service pack is

available under <sdk-installation>\tools\cc32xx_tools\servicepack-cc3x20. To program the service pack

with an UniFlash, the binary file (.bin) must be loaded to the Files/Service Pack.

1.3 UniFlash Tool

UniFlash is a stand-alone tool used to program on-chip flash memory on TI MCUs and onboard flash

memory for Sitara processors. The tool lets the developer download application image, service pack, and

other files on the serial flash of the CC3220 device. It also enables the creation of OTA (Over-The-Air)

images.

1. Download the Image Creator tool from http://www.ti.com/tool/uniflash.

2. Run the installer by double-clicking on it. Click Next to continue, as shown in Figure 1-1.

1.4 Serial Terminal

Many sample applications come with UART support for printing the debug information or the status of any

operation. Some applications require user’s input through UART, so it is advised to install a serial terminal

application. Tera Term is used for demonstration here.

1. Download Tera Term and install as described in the instructions.

2. Run the Tera Term application.

3. Select the Serial Port, then COM11: XDS110 Class Application/User UART (COM11), as shown in

Figure 1-4. Click OK to continue.

NOTE: Install the XDS110 drivers for the PC to enumerate these ports for serial terminal. See

Section 1.6 for installation of the XDS110 drivers.

Figure 1-4. Select Serial Port

4. Go to Setup →Serial port, as shown in Figure 1-5.

1.5 Pin Mux Tool

TI recommends installing the Pin Mux Tool, although it is not required to get started with your sample

application. This tool helps to configure the pin mux setting for your application. All the provided sample

applications already contain the required pin mux file (output of this tool). The latest version of this tool

can be downloaded from http://www.ti.com/tool/PINMUXTOOL. For more information on this tool, see

http://processors.wiki.ti.com/index.php/TI_PinMux_Tool_v4.

For older versions of this tool, the CC3220 device may not be listed explicitly under the supported devices.

If that is the case, choose the CC3200 device from the drop-down menu to generate the same output files

required by the CC3220 device.

1.6 XDS110 Driver Installation

XDS110 drivers must be installed before one can use the debugger or the Image Creator tool. It also

enumerates the serial terminal port, which can be used to print the debug messages over UART. The XDS

drivers can be obtained from the

http://processors.wiki.ti.com/index.php/XDS_Emulation_Software_Package#XDS110_Reset_Download.

Do the following steps for the installation.

1. Run the installer in administrator mode and click Next, as shown in Figure 1-7.

1.7 Debugger/IDE

The following debugger/IDE can be used to download and debug the application image.

1.7.1 CCS

The latest CCS installer can be downloaded from http://www.ti.com/tool/ccstudio. CCS is a free tool from

TI, lets developers work with various TI devices. The SDK supports CCS version 7.0 or later.

1. Double-click on the installer and follow the instruction to install this tool

2. Make sure to select the SimpleLink Wireless MCUs option for processor support, as shown in Figure 1-

11. Click Next to continue.

NOTE: If CCS is already installed for other processors (and not for SimpleLink wireless MCU), then

the installer must run again and select the SimpleLink Wireless MCUs option for processor

support this time. The rest of the installation steps will remain the same as for a new

installation:
