2.4 Install the MSP430™ CDC Driver
To determine if the CDC driver for the MSP-EXP430F5529LP is installed, run Device Manager on the PC
after the firmware example has been flashed to the LaunchPad development kit. For Windows users, this
can be done by going to Control Panel → Device Manager → Other Devices.
It is mandatory that the firmware be flashed on the MSP-EXP430F5529LP first. This is because it is the
firmware example that attempts to enumerate the CDC port to the COM port list, and there is no way to
tell if the CDC driver is installed or not unless the firmware attempts that CDC port enumeration.
If the MSP430 LaunchPad development kit appears as an Other or Unknown device with a caution symbol
(see Figure 5), then the CDC driver is not installed.

3.2 Proper Interaction of NFC Devices With the DLP-7970ABP BoosterPack Plug-in
Module
Due to the short range of NFC technology, correct presentation of the BoosterPack plug-in module and
any NFC enabled device is required for proper NFC operation to occur. This is done by aligning the NFC
antennas of each device so they are coupled correctly. This section contains figures that show correct and
incorrect presentations to an NFC BoosterPack plug-in module using an NFC-enabled smartphone, an
NFC/RFID tag, and another NFC BoosterPack plug-in module. Throughout this document, any comments
referring to present or presenting an NFC device or tag to the BoosterPack plug-in module refers to the
following information.
The antenna of the BoosterPack plug-in module is located above the IC circuitry and is indicated by the
traces etched into the PCB, which is the antenna coil (see Figure 11). The IC package that is labeled DLP
Design is not an antenna and cannot be used for NFC communication.

Figure 12 shows correct and incorrect presentation of a NFC enabled phone to the BoosterPack plug-in
module. The antennas on NFC enabled phones vary based on phone model. Typically, a good point of
reference is near the phone battery for most models. Most Android phones need to be unlocked for NFC
communication to occur. By default, NFC-enabled phones do not enable NDEF card emulation.

Figure 13 shows the proper presentation of a tag to the BoosterPack plug-in module. Similar to the NFC
enabled phone, robust communication does not occur when the tag is presented to the IC circuit. Also, if
the tag is presented beneath the LaunchPad development kit, it is on the edge of the NFC communication
range of the BoosterPack plug-in module, and the LaunchPad development kit ground plane shields the
NFC communication.

Figure 13. Tag Correct and Incorrect Presentation to BoosterPack™ Plug-in Module
Figure 14 shows the correct and incorrect presentation of two BoosterPack plug-in modules. When two
BoosterPack plug-in modules are used, the antennas on the BoosterPack plug-in modules should be
aligned on top of each other. The antennas have weaker coupling when placed side-by-side horizontally
or vertically.

TI NFC Tool GUI
3.3 NFC Operation Modes
Near Field Communication (NFC) offers three different modes of operation: Peer-to-Peer (P2P),
Reader/Writer (RW), and Card Emulation (CE). This section discusses operation of each mode with the
NFCLink Standalone GUI. For more information on NFC, visit www.ti.com/NFC.
3.3.1 Peer-to-Peer Mode
Peer-to-Peer (P2P) mode allows two NFC-enabled devices to communicate bidirectionally where both
devices are able to initiate communication as needed.
Common use cases for P2P include sharing content from device to device, firmware updates, and pairing
applications.
For detailed information about how Peer-to-Peer communication operates with the TRF7970A, see NFC
Active and Passive Peer-to-Peer Communication Using the TRF7970A.
3.3.1.1 NFC Configuration Tab
The Target Mode(s) and Initiator Mode(s) allow the user to select multiple modes that determine if the
TRF7970A acts as a target or an initiator and if passive or active communication is used (see Figure 15).
After selecting which modes to enable, click Start P2P. The NFC enabled devices poll or listen based on
the selected P2P modes.
www.ti.com
Figure 15. NFC Configuration Tab – P2P Configuration
3.3.1.2 Peer-to-Peer-Tab
When Peer-to-Peer mode is enabled and a connection is established between the TRF7970A and an NFC
device that is presented, the Peer-to-Peer tab automatically opens (see Figure 16). The P2P Status pane
includes information about the current mode, bitrate, technology, bytes received since the P2P
communication started, and the RSSI value. The Receive pane displays P2P messages received by the
TRF7970A.
When NFC Data Exchange Format (NDEF) messages are received, the GUI attempts to parse the data
and display it in ASCII. Text and URI Record Type Definitions (RTDs) are automatically parsed. Other
NDEF messages are displayed as an unknown RTD. Any non-NDEF formatted messages is shown in the
pane as raw data. Any NDEF messages received can also be found inside the NDEF.hex file located at
[Install Path] \tools\TI NFC Tool\TI NFC Tool\bin\Debug.
Most NFC enabled smartphone apps use the NDEF message format to exchange information over P2P
communication such as text messages and URLs.

www.ti.com
The Transmit pane supports sending out Text RTDs or URI RTDs from the TRF7970A to the connected
NFC device. The GUI limits the message length to 246 bytes.
When the NFC device is removed, then the Peer-to-Peer tab automatically switches back to the NFC
Configuration tab.
TI NFC Tool GUI
3.3.2 Reader/Writer Mode
Reader/Writer mode allows an NFC enabled device to read data from and write data to various NFC and
RFID tags, transponders, and contactless smartcards. Supported standard tag types are:
• NFC Forum Type 2 Tags (T2T)/ISO14443A
• NFC Forum Type 3 Tags (T3T)/FeliCa
• NFC Forum Type 4A Tags (T4TA)/ISO14443A
• NFC Forum Type 4B Tags (T4TB)/ISO14443B
• NFC Forum Type V Tags (T5T)/ISO15693
Common use cases for Reader/Writer mode include access control, product authentication, and pairing
applications.
For detailed information about how Reader/Writer mode operates with the TRF7970A, see NFC/HF RFID
Reader/Writer Using the TRF7970A.

3.3.2.1 NFC Configuration Tab
Use the check boxes in the Reader/Writer section to choose which technologies to enable for the
TRF7970A and then click the Start RW button (see Figure 17). Only one NFC/RFID tag should be
presented to the RF field at a time when using Reader/Writer mode.
Figure 17. NFC Configuration Tab – RW Configuration
www.ti.com
3.3.2.2 Reader/Writer Mode Tab
When Reader/Writer mode is enabled and a supported NFC tag is presented, the Reader/Writer tab
automatically opens (see Figure 18). The RW Status pane includes information about the tag type being
read, bitrate of the communication, NFC technology, RSSI value, and Unique Identifier (UID) of the tag.
The Tag Content pane displays the contents of a tag that has been read when applicable. If an NDEF
message is stored inside the tag, the GUI attempts to parse the message and display it in ASCII. Text and
URI RTDs are automatically parsed. Other NDEF messages are displayed as an unknown RTD. If the tag
is not NDEF formatted, then the pane displays all raw data read from the tag. Any NDEF messages
received can also be found inside the NDEF.hex file located at: [Install Path]\tools\TI NFC Tool\TI NFC
Tool\bin\Debug
The Tag Write pane can be used to write a custom Text RTD or URI RTD to a presented tag by pressing
the WRITE button. The Tag Content screen displays a message to indicate whether or not the write was
successful. The GUI limits the message length to 246 bytes. It also can be used to format T5T tags for
NDEF messages with the FORMAT button.
When the tag is removed, then the Reader/Writer tab automatically switches back to the NFC
Configuration tab.

Figure 19. NFC Configuration Tab – CE Configuration
www.ti.com
3.3.3.2 Card Emulation Tab
When Card Emulation mode is enabled and an NFC device capable of reading the emulated tag is
presented, the Card Emulation tab automatically opens (see Figure 20). The CE Status pane includes
information about the tag type being emulated, the bitrate of the communication, which NFC technology is
being used, the RSSI value, and the emulated Unique Identifier (UID).
The Received Read/Write Cmds pane displays each command being sent to the TRF7970A by the NFC
device. Read and Write commands are both displayed along with details about which files are being read
and how many bytes are read from them.
The Emulated Content pane can be used to emulate a custom message that can be either a Text RTD or
URI RTD. The message length is limited to 248 bytes in the GUI.
