1 Getting Started
1.1 Introduction
xWR6843ISK/IWR6843ISK-ODS/ IWR6843AOPEVM and MMWAVEICBOOST are part of mmWave EVMs
hardware. The xWR6843 antenna board from Texas Instruments is an easy-to-use evaluation module for the
xWR6843 mmWave sensing device. This board contains 60-GHz mmWave Radar transceiver in which antennas
are etched on PCB or on packager and act as the Radar front-end board. The MMWAVEICBOOST is an add-on
board used with TI's mmWave sensor used in all starter kits to provide more interfaces and PC connectivity to
the mmWave sensors. The MMWAVEICBOOST board provides an interface for the mmWave Studio tool to
configure the Radar device and capture the raw analog-to-digital converter (ADC) data, using a capture board
such as DCA1000 evaluation module (EVM). xWR6843 antenna EVMs and MMWAVEICBOOST contains
everything required to start developing software for on-chip C67x DSP core and low-power ARM R4F controllers.
It provides an interface to the MSP43xx boards through 40-pin LaunchPad™/ BoosterPack™ connectors.

2.3 Muxing Scheme for Multiple Sources
There are multiple sources as shown in Figure 2-4 such as 40 pin LP/BP, DCA1000 EVM, onboard FTDI and
XDS110 that can control the Radar front-end chip in the starter kit. This is done with the help of mux scheme
implemented on the MMWAVEICBOOST. Follow the switch settings as shown in Table 2-1 to avoid the conflicts.
The most used configuration is the default position.

2.4 Using the MMWAVEICBOOST With the Starter Kit
The MMWAVEICBOOST board is required with the starter kit for the following use cases:
• PC connection is enabled for communicating with the mmWave front end chip
• Connecting to mmWave Studio (mmWave Studio is a tool that provides capability to configure the
MMWAVEICBOOST front end from the PC). This tool is available online.
• The DCA1000 EVM allows users to capture the raw ADC data over the high-speed debug interface and post
process it in the PC.
• Getting DSP trace data through the MIPI 60-pin interface
• DMM interface can be used
2.4.1 PC Connection
Connectivity is provided through the micro USB connector over the onboard FTDI and XDS110 ICs. This
provides the following interfaces to the PC:
• XDS110 provides the default UART interface for application/user port and auxiliary data port
• FTDI Port A -> SPI interface for radar device control using mmWave Studio
• FTDI Port B-> I2C interface and host INTR signal
• FTDI Port C -> BSS Logger port (for internal debug only), NRST control, and Nerror signals
• FTDI Port D -> DSS Logger port, SOP line control signals, and GPIO signals
When the USB is connected for the first time to the PC, Windows® maybe not be able to recognize the device.
This is indicated in the device manager with yellow exclamation marks as shown in Figure 2-8.

To install the devices:
1. Download the latest FTDI and XDS110 drivers available in the mmWave SDK package.
2. Right click on these devices.
3. Update the drivers by pointing to the location where the FTDI and XDS110 drivers are downloaded.
This must be done for all eight COM ports. When eight COM ports are installed, the device manager recognizes
these devices and indicates the COM port numbers, as shown in Figure 2-9.
Figure 2-9. COM Ports After the Driver Installation
2.4.2 Flashing the QSPI Flash on the Antenna Module
For the flashing, only one USB cable (XDS110 USB) must be connected to the PC; the Uniflash utility must be
used load the binary onto the antenna module. Connecting both XDS110_USB and FTDI_USB can prevent the
uniflash utility from running successfully.
2.4.3 MMWAVEICBOOST and Antenna Module Connections for Modular Testing
A compatible antenna module can be stacked on top of the MMWAVEICBOOST board using the two 60-pin HD
connectors and 12 nuts, four washers, and four M3 screws (for improving the thermal performance). Connectors
have a pin number marking shown in Figure 2-18 to prevent the misalignment of the pins or reverse connection.
Figure 2-10 shows the integration of MMWAVEICBOOST and starter kit. The starter kit is powered by the 3.3-V
supply. There is one micro USB cable to XDS110 (J11) to run the out-of-box demo, and one micro USB cable to
FTDI (J12) for initiating controls from mmWave Studio. Digital controls from the MMWAVEICBOOST are initiated
after the FTDI and XDS110 ports are detected in the device manager shown in Figure 2-9. The configuration of
the MMWAVEICBOOST and starter kit are based on the analog mux settings and mux controls received from the
dip switch (S1). To mux all the digital controls to the FTDI/XDS110 connector, set the mux control switch
positions to ON/OFF, as shown in Table 2-1.

2.5 Interfacing with the DCA1000EVM
The high-speed LVDS data from the radar device can be captured using the DCA1000 EVM. For more
information about the DCA1000 EVM and ordering details, see the Real Time Data Capture Adapter and the
DCA1000EVM Data Capture Card User's Guide. mmWave Studio is required for configuration. For the
installation of the tool, see the mmWave Studio User's Guide.
2.5.1 mmWave Studio Interface
To control the radar device from mmWave Studio, both the starter kit and the MMWAVEICBOOST must be
powered and connected to the PC using the micro USB cable. The UART used to download the firmware is
accessed from the XDS110 device on the MMWAVEICBOOST. The SPI interface used to control the radar
device, SOP controls, and nRST control is performed from the FTDI chip on the MMWAVEICBOOST. For details
on the usage of mmWave Studio, see the Radar Studio User's Guide that is part of the DFP package.
2.5.2 MMWAVEICBOOST and Antenna Module Configuration
The configuration of the MMWAVEICBOOST and starter kit are the same as mentioned in Section 2.4, except
the analog mux settings and the mux controls are received from the 60-pin connector (J10) instead of FTDI. To
mux all the digital controls to the 60-pin connector, the mux control switch positions should be set to ON/OFF, as
shown in Table 2-1,
2.5.3 DCA1000 EVM Connection
The DCA1000 EVM must be powered up with a 5-V supply and the micro-USB Ethernet cable connected to the
same PC as the MMWAVEICBOOST and antenna module. A 60-pin Samtec cable (HQCD-030-02.00-SEU-
TBR-1) is used to connect the 60-pin connector (J10) on the MMWAVEICBOOST to the J3 input connector on
the DCA1000 EVM. Mount the four stand offs, four washers, and pan head screws to mate with the
DCA1000EVM. For more information, see the setup shown in Figure 2-12.
Note
The Samtec cable included in the kit is the HQCD-030-02.00-SEU-TBR-1. "02.00" indicates the length
of the cable in inches; cables with longer length can be ordered by the user if needed.
