CAPTIVATE-EMC Getting Started Guide
1 Introduction
The CAPTIVATE-EMC is an evaluation board that lets you easily evaluate the electromagnetic
compatibility performance of CapTIvate technology relative to your design requirements. The EVM
features the MSP430FR2676 CapTIvate MCU with hardware accelerated frequency hopping and
oversampling. This EVM demonstrates how to design hardware and software that can pass challenging
system-level tests for conducted RF immunity, electrical fast transient and burst immunity, electrostatic
discharge immunity, and radiated immunity.
Figure 1. CAPTIVATE-EMC Board
Free software development tools are also available, such as TI's Eclipse-based Code Composer Studio™
IDE (CCS) and IAR Embedded Workbench®IDE.

EMC).
2 Required Tools
The following tools are required to use CAPTIVATE-EMC:
• A CAPTIVATE-EMC evaluation board programmed with the CAPTIVATE-EMC-Demo firmware
example
• A CAPTIVATE-PGMR MCU programmer
• A CAPTIVATE-ISO communication isolation board
• A DC power supply that can output 12 VDC at 1 A. The CAPTIVATE-EMC accepts 5-V to 20-V DC
power supply input.

3 Hardware
The following sections describe the CAPTIVATE-EMC hardware (see Figure 2). For a detailed description
of the hardware, see the CAPTIVATE-EMC hardware description in the CapTIvate Technology Guide.

3.3 Power Supply
There are two power supply options for CAPTIVATE-EMC board (see Figure 4):
• 5 V to 20 V DC power through connectors JP1 and JP2. The color of the connectors shows the
polarity, red for positive and black for negative. A TI TPS7A4533 +3.3-V 1.5-A LDO provides power for
all the devices on the CAPTIVATE-EMC.
• The CAPTIVATE-PGMR board also can provide 3.3-V power supply to the CAPTIVATE-EMC through
connector J1.
Figure 4. CAPTIVATE-EMC Power Supply Options
NOTE: Do not connect the CAPTIVATE-PGMR directly to the CAPTIVATE-EMC when a DC power
supply is enabled.
3.4 Debug Connector
The 20-pin debug connector J1 is for interfacing to the CAPTIVATE-PGMR board. This connector
provides power, Spy-Bi-Wire, and UART connectivity with the CAPTIVATE-PGMR module.
The Spy-Bi-Wire port lets the user download and debug their own code or the demo code to the
MSP430FR2676 MCU on the CAPTIVATE-EMC board.
The MSP430FR2676 MCU communicates with a dedicated USB HID Bridge MCU located on the
CAPTIVATE-PGMR module using UART to send sensor data and status to the CapTIvate Design Center
as part of the sensor design and tuning process.
4 Getting Started
To get started with the CAPTIVATE-EMC, see the CAPTIVATE-EMC Getting Started section of the
CapTIvate Technology Guide.
An easy way to get started with the EVM is by using its preprogrammed out-of-box code. This code
demonstrates some key features of the EVM.

CAPTIVATE-EMC Getting Started Guide
4.1 Setting up the Hardware
CAPTIVATE-EMC is designed to accommodate various powering methods, including through the 20-pin
connector from CAPTIVATE-PGMR and a banana jack connector from a DC power supply.
CAUTION
Do not enable both power supplies at the same time because this can damage
the CAPTIVATE-PGMR board.
Figure 5. Hardware Setup
4.2 Running the Out-of-Box Demo
By default after power up, the CAPTIVATE-EMC development kit runs system initialization and capacitive
touch calibration. When this initialization is finished, the POWER LED illuminates, the RUN LED blinks, all
other LEDs are off, and the beeper is off. Touch a button on the CAPTIVATE-EMC panel to turn on or turn
off the indicator LED above that button. The DETECT LED illuminates and the speaker beeps when a
button is touched.

4.3 Using CapTIvate Design Center
Figure 7 shows the options for connecting the CAPTIVATE-EMC to a host computer:
• Connect the CAPTIVATE-EMC to a host computer with the CAPTIVATE-PGMR and remove the
connection from the DC power supply.
• Keep the DC power supply and connect the CAPTIVATE-EMC to a host computer with CAPTIVATE-
PGMR and CAPTIVATE-ISO.
Open CapTIvate Design Center on the host computer.
Figure 7. Connection to CapTIvate Design Center
Open the FR2676_CAPTIVATE-EMC example project in CapTIvate Design Center. Select
Communications →Connect from the menu bar in CapTIvate Design Center to enable target
communications. When the user touches a button, the button status is reflected in CapTIvate Design
Center (see Figure 8).
