Introduction
Thank you for purchasing a CC2543-CC2544 Development Kit.
The CC2543 and CC2544 devices are RF SoCs designated for the proprietary 2.4 GHz RF market
that can be used in any application but are tailored for wireless HID applications. The CC2544 is
tailored for the USB dongles and the CC2543 for peripheral devices such as wireless mouse
applications.
The single-chip RF transceiver and MCU supports data rates up to 2Mbps, and has extensive
baseband automation, including auto-acknowledgement and address decoding. It provides excellent
link budget with programmable output power up to +4dBm, which enables long range without external
front-ends.
The CC2543 and CC2544 devices come with a powerful two-channel DMA which reduces the need of
the MCU operating in active mode, hence significantly improves power consumption. In addition they
have one 16-bit and two 8-bit timers and 20mA drive strength on selected general purpose I/O pins.
They also have a 40-bit radio timer used by the Link Layer Engine.
The on-chip voltage regulator supports a wide range of supply voltages, and the CC2544 has a USB
5V to 3.3V regulator. The on-chip MCU is the High-Performance and Low-Power 8051 Microcontroller
with Code Prefetch.
The CC2544 has full speed USB support with 6 endpoints, separate 1kB FIFO memory, internal pullup and 5V to 3.3V regulator.
The CC2543 and CC2544 product folders on the web [1][2] have more information, with datasheets,
user guides and application notes.
The CC2543-CC2544 Development Kit includes all the necessary hardware to properly evaluate,
demonstrate, prototype and develop software for proprietary applications

Getting started
Setting up the hardware
After opening the kit, make sure you have all components. Please contact your TI Sales
Representative or TI Support [6] if anything is missing.
Start by connecting the antennas to the SMA connector on the RF evaluation boards. Tighten the
antenna’s screw firmly on to the SMA connector. If not properly connected, you might see reduced RF
performance. It is also possible to connect the EM board to RF instruments via coax cables. The EM is
designed to match a 50 Ohm load at the SMA connector.
Next, the evaluation modules should be plugged in to the SmartRF05EB. Make sure to set the switch
P19 to “SOC/TRX” (right position). The purpose of the SmartRF05EB is to serve as a general I/O
board for testing of the various peripherals of the CC2543 microcontroller. The EB also contains a
separate USB controller, which is used as a bridge between the PC and the CC2543 and the CC2544
for programming the flash of these devices. It is also used for debugging the software running on the
CC2543 and CC2544.
The evaluation board can be powered from several different sources:
2 x 1.5V AA batteries (included in this kit)
USB (via the USB connector)
DC power (4 to 10 Volt) (not included in this kit)
External regulated power source (not included in this kit)
The power source can be selected using jumper P11 on the SmartRF05EB. The SmartRF05EB User’s
Guide [8] provides more details.
After assembling the hardware, you now have several options for working with the CC2543 and
CC2544:
Run the packet error rate (PER) test which is preprogrammed on the CC2543 and
CC2544. The PER test is a quick way to evaluate the range which can be achieved with the
radio. Chapter 5.2 will guide you through the PER test.
Evaluate and explore the RF capabilities of the CC2543 and CC2544 using SmartRF
Studio. Chapter 5.3 provides the details how to do so.
Developing software for the CC2543 and CC2544. Install IAR Embedded Workbench for
8051 and set up your first software project. Chapter 5.4 explains how.

5.2.1
Running the Preprogrammed PER Test on the CC2543EM and the CC2544Dongle
Introduction
The CC2543EM and CC2544Dongle come pre-programmed with a Packet Error Rate (PER) test
application. The PER number is the ratio between number of packets being lost and the total number
of packets being sent. The PER relates to the more traditional Bit Error Rate (BER) through the
formula
PER
1
(1
BER )
packet _ length
A PER value of 1% is normally used as the limit for determining the sensitivity threshold of the radio.
The sensitivity threshold is the lowest input signal strength at which the receiver can decode the signal
with a reasonable degree of correctness.
By using the PER test on the CC2543 and the CC2544, it is possible to perform practical range
testing. Place the transmitter at a fixed location and place the receiver at a given distance from the
transmitter. Then run the PER test to measure packet errors and monitor the signal strength. Read the
description below for an explanation how the PER and RSSI values are calculated. Repeat at different
distances to get an idea of the range that can be obtained.
To get an idea of the best performance of the device, the test should be performed outdoors on a
large field with no other RF sources to avoid fading, reflections, and uncontrolled interference.
Alternatively, the range test can be used to see what range is obtainable in the actual environment
where the RF system is going to be deployed. See document [11] for considerations and applicable
theory for performing open field range measurements.
The CC2543-CC2544DK Quick Start Guide (www.ti.com/lit/swru315) gives a detailed step-by-step
guide for running the PER test. We recommend following the steps in that guide.
Please note the following:
The most natural power source to use for range testing is batteries. There is a voltage
regulator on the SmartRF05EB that regulates the voltage to 3.3V on the board, regardless of
the voltage from the batteries.
Both boards have to be set up to operate on the same channel. The available channels are in
steps of 1 MHz from 2402 MHz up to 2480 MHz.
The PER value is calculated using the following formula:
PER
NumPackets Lost
NumPackets OK
NumPackets Errors
NumPackets Lost
NumPackets Errors
The software is looking at the sequence number of the received packet to determine how
many packets are lost since the last received packet. The PER value on the LCD shows the
number per 1000 to avoid time consuming floating point calculations on the controller. That is,
if the LCD shows a PER of 6 ‰, the PER value is 0.6%.
The RSSI value shown on the LCD is in dBm and represents a running average RSSI value
from the last 8 received packets. The RSSI value will never be the same for all packets even
though the boards are located at the same distance from each other. This is caused by
interfering signals, reflections, thermal noise etc.
The source code for the PER test, and an Intel HEX file ready to be programmed on the device is
available on the CC2543-CC2544DK web site [3].
8/31
swru318
5.2.2
Program Flow
The PER test has two modes of operation, MASTER mode and REMOTE mode. The CC2543 can run
both while the CC2544 can only run the MASTER mode. This is because the CC2544 is mounted on
the CC2544 USB Dongle board which has no graphical user interfaces (required for REMOTE mode
operation). When the CC2544Dongle is powered up it automatically enters MASTER mode and no
further action is required from the user. In this section the PER test will be explained for the
CC2543EM mounted on the SmartRF05EB.
To get a quick walkthrough on how to set up the PER test confer the “CC2543-CC2544DK Quick Start
Guide” [4]. A printed copy of this is included in the kit. The source code for the PER test can be
downloaded from the kit product page [5].
When the preloaded PER test is powered on the CC2543EM (mounted on the SmartRF05EB) the
user will be presented with a choice between the two modes of operation (MASTER and REMOTE).
The operations of these two modes are presented below.
5.2.2.1
MASTER Mode
When a device enters the MASTER mode it can be described as a MASTER device. When this mode
is started the program enters the function “master_beacon_mode” In this function the device is
configures the radio in a default state (Modulation: GFSK, Data rate: 250kbps, Frequency: 2402 MHz)
and starts transmitting a beacon packet every 10 ms. After every transmitted packet the MASTER
device listens for a acknowledgement packet containing configuration settings for a new PER test. If
this configuration packet is received, the MASTER device reads out the packet content and then
enters a new function called “master_per_test_mode”. In this function the radio is configured
according the settings given in the configuration packet. Then the radio starts transmitting the given
number of packets at a rate of 10 ms. For every sent packet the REMOTE device will send an empty
acknowledgement. If the MASTER device receives these acknowledgements the bottom line on the
LCD display will state the following status: “Remote: ONLINE”. If the MASTER device does not receive
these acknoledgmenets the bottom line will say: “Remote: OFFLINE”. After the MASTER device is
finished transmitting all the packets, it will go back to the function “master_beacon_mode” and send a
beacon packet every 10 ms.
5.2.2.2
REMOTE Mode
When a device enters the REMOTE mode it can be described as a REMOTE device. When this mode
is started the program query the user for a PER test configuration. It will ask the user to choose
frequency, modulation type, packet length, number of packets to be sent and LNA gain (Only for data
rates ≠ 2Mpbs). All of these options will be stored in an array called “ack_config”. The joystick (U1)
and button1 (S1) on the SmartRF05EB is used to change and select the different options for the test
configuration.
After the choices have been completed by the user, the program enters the function called
“remote_per_test_setup_mode”. In this function the REMOTE device configures the radio in a default
state (Modulation: GFSK, Data rate: 250kbps, Frequency: 2402 MHz) and starts to listen for “beacon
packets” from a MASTER device. If it receives a beacon packet, the REMOTE device will transmit an
acknowledgement containing the information previously stored in the “ack_config” array. It will repeat
this whole process for 100 ms. If it has not received a beacon packet and transmitted a
acknowledgement within 100 ms, the user is queried with the following message: “No Beacon Signal”.
The user can then chose to retry by pushing button1 on the SmartRF05EB or to set up a new test by
pushing the joystick (U1) up and then pressing button1(S1).
If a beacon packet was received and an acknowledgement was sent the program enters the function
called “remote_per_test_mode”. In this function the REMOTE device go in to a Rx state and
continuously updates the LCD on the SmartRF05EB with the packet error rate, the Received Signal
Strength Indication value (RSSI) and number of good packets received. When the test is finished the
user is presented with the final result. The user can then move the joystick down to access the second

swru318
result screen which contains the number of good packets received, number of packets with CRC error
received and the number of lost packets. If the user pushes button1 (S1) a choice between restarting
the same test again or to set up a new test is presented.
5.2.2.3
Flow Chart
In Figure 2 - Simplified Flow Chart for the CC254x PER Test a simplified flow chart describing the
PER test functionality is presented. Here the reader can see the program flow for the PER test running
on the CC2543EM mounted on a SmartRF05EB. Some minor details of the program are omitted.

swru318
5.2.3
Set Up the CC254x PER Test
The PER test can be set up between two CC2543EMs or one CC2543EM and a CC2544 USB
Dongle. The CC2544Dongle has no graphical user interface so it is limited to MASTER mode
operation. It is set to the MASTER mode by default when powered.
Make sure that only one MASTER device is running! The use of multiple MASTER devices will cause
the PER test to malfunction. This is because the REMOTE device will auto-acknowledge all beacon
signals from any MASTER device and multiple MASTER devices might then start transmitting
simultaneously. After a single MASTER device has been powered up, leave it on the desired test
location and continue setting up a REMOTE device.
The test can be set up and started remotely through the REMOTE device. If the user needs to restart
the test at any time while a test is running, simply press “Button 1” (S1) on the SmartRF05EB. While
the button is pressed the test is halted on the REMOTE device while the MASTER device continues
normal operation. When the button is released the REMOTE device remotely restarts the test for both
MASTER and REMOTE. If the user wants to set up a new test while a test is running, simply push the
joystick like a button. The REMOTE device will remotely make the MASTER abort the current test and
make it go back to beacon mode. At the REMOTE device the user will be queried for the configuration
for a new test. This happens when the joystick is pressed, there is no functionality linked to the release
of the joystick button.
5.3
Evaluate the CC2543 and CC2544 Radio using SmartRF Studio
SmartRF Studio is a PC application developed for configuration and evaluation of many of the RF-IC
products from Texas Instruments, including the CC2543 and CC2544. The application communicates
with the CC2543 and CC2544 via the USB controller (the CC2511) on the SmartRF05EB board. The
USB controller uses the debug interface of the CC2543/44 to execute commands and to read and
write registers. Refer to Figure 8 - CC2544 USB Dongle connected to SmartRF05EB for a picture
showing how to connect the CC2544Dongle to the SmartRF05EB.
SmartRF Studio lets you explore the radio on the CC2543/44, as it gives you full overview and access
to the radio registers. The tool has a control interface for running basic radio performance tests from
the PC. SmartRF Studio also offers a flexible code export function of radio register settings for
software developers.
Before proceeding, please download and install the latest version of SmartRF Studio from the web [9].
By installing Studio, the USB drivers needed for proper interaction between the PC and the hardware
of the CC2543-CC2544DK will also be installed.
In order to use the SmartRF Studio with CC2543 and CC2544, connect the CC2543EM or
CC2544Dongle to the SmartRF05EB. Next, connect the SmartRF05EB board to the PC via one of the
USB cables included in the kit. If you have installed SmartRF Studio, select automatic installation of
driver in the device wizard that appears. The device wizard will only pop up when you turn on the
SmartRF05EB and only once for each board. Allow Windows to complete the driver installation before
proceeding.
With the board connected to the PC, you can start SmartRF Studio. The following window should
appear:

output power.
Export device register values in a user modifiable format by clicking the “Code export” button
in the Register view panel (on the left side).
The SmartRF Studio User Manual has more details.
5.4
Setting up the Software Development Environment
To develop software and debug an application on the CC2543 or CC2544, it is recommended to use
IAR Embedded Workbench. It supports debugging of CC2543 and CC2544 through the
SmartRF05EB, so no additional hardware is required.
IAR EW8051 is bundled with all the required files for CC2543 and CC2544 to start development:
Register definition header file
Linker command file
Driver and device description file needed for debugging and programming
Note that other compilers and linkers can be used, but these tools may have limited debugging
capabilities.
An evaluation version of IAR Embedded Workbench is included in the Development Kit. To install the
software, insert the CD and follow the instructions. You will be asked to register on IAR’s web site to
get a license key for the product. As the owner of a CC2543-CC2544 Development Kit, you are
entitled to a 60 day evaluation period. The evaluation version in the kit automatically gives you 30
days. Please contact your local IAR sales representative for the additional 30-days evaluation period.
For a list of sales offices and distributors in your country, please see this site:
http://www.iar.com/contact.
Appendix A in this document will guide you through the steps of setting up your own project from
scratch.

RF Testing
NB! When running RF performance tests, it is recommended to disable all other peripherals on the
SmartRF05EB in order to avoid unwanted noise on the on-board voltage. In particular, make sure the
RS232 level converter/line driver is disabled.
RF testing can be performed by using SmartRF Studio together with the Development Kit. The basic
set-up is described in section 5.3. As described in that chapter, SmartRF Studio can be used to set up
basic tests and tune RF registers accordingly.
Since the CC2543 evaluation module is equipped with an SMA connector, both radiated (via antenna)
and conducted (via cable) tests can be performed, and it is easy to hook the EM up to RF
measurement equipment. For the CC2544Dongle it is only possible with radiated tests as this device
has an on board PCB antenna. The RF equipment may be connected in two different ways.
To measure radiated performance, connect an appropriate antenna to the spectrum analyzer
or power meter and an antenna on the EM board.
To measure conducted performance, connect a 50 Ohm coaxial cable directly from the EM to
the RF equipment.

Figure 5 - RF Test Set-Up with a Spectrum analyzer
By using good-quality RF cabling, the loss in the cabling should be negligible. However make sure that
the spectrum analyzer is calibrated. If possible, check it against a calibrated instrument such as an RF
signal generator. Un-calibrated spectrum analyzers can display errors of several dBs.
For more information regarding RF testing, refer to “Application Note 103 -- Basic RF Testing of
CCxxxx Devices” [12].
6.1
TX Parameter Testing Basics
To investigate the TX performance of the CC2543 and the CC2544, you can either use a Spectrum
Analyzer or an RF Power Meter. Use the “Continuous TX” test mode in SmartRF Studio to set up the
device to transmit a signal at the desired frequency. Both a modulated or unmodulated carrier signal
can be generated.
Use the RF Power Meter to observe the output power or the spectrum analyzer to observe the
spectrum and to measure the error vector magnitude (EVM).
14/31
swru318
6.2
RX Parameter Testing Basics
To investigate the RX performance of the CC2543 or CC2544, you can use a signal generator or
“Packet TX” in SmartRF Studio (with another EB+EM) to generate the packets to receive. The receiver
can be configured by using the “Packet RX” test feature in SmartRF Studio.
By adding a jammer (a third node that generates either noise on the same channel or a strong signal
on an adjacent channel) it is also possible to measure co-channel rejection and selectivity/blocking
performance.
The PER test application, that was described in section 5.2, can be used for simple sensitivity
measurements with the CC2543EM and/or with your own prototype hardware. In this case, connect
the unit you want to test to a known good transmitter with coaxial cables and attenuators. Add more
attenuators until the PER value is 1%. The signal strength at the receiver side is then the sensitivity
limit of the system.
For more information regarding sensitivity measurements, refer to “Design Note 2 – Practical
Sensitivity Testing” [10].

10 Frequently Asked Questions
Q1
When connecting the SmartRF05EB to my PC via USB, the dialog window below appears.
Why? What should I do?
A1
The SmartRF05EB will be recognized as a USB device by the operating system, and it will ask
the user to provide information about which USB driver that should be associated with the
device.
If you have installed SmartRF Studio, just follow the instructions and select “Automatic
installation”. Windows should find the required driver automatically. The drivers are included in
the SmartRF Studio installation.
Q2
SmartRF05EB with the CC2543EM or CC2544Dongle is not detected by IAR/SmartRF
Studio. Why?
It might be that the USB driver installation failed. The most common reasons are either Windows
not finding the driver or the user ignoring the “Found New Hardware Wizard”.
First of all, make sure you have installed SmartRF Studio, which includes the appropriate drivers
for the evaluation board. The drivers for the evaluation board are normally located in the
directory C:\Program Files (x86)\Texas Instruments\SmartRF Tools\Drivers, where C:\Program
Files (x86)\Texas Instruments\SmartRF Tools\ is the default root installation directory for
SmartRF Studio. The path may be different if you have chosen a different installation directory
for SmartRF Studio.
Next, make sure you follow the steps in the hardware wizard. It is necessary to follow the steps
for driver installation for each new board that is connected to the PC. If the automatic driver
installation (as described in A1 above) fails, please select manual installation of drivers. When
prompted by the wizard, select “Browse my computer for driver software”. You will see the
following window.
20/31
swru318
If the above fails, select “Let me pick from a list of device drivers on my computer.” A new
window will open, asking for a location of where drivers can be found. Locate the SmartRF05EB
file and select that driver for installation.
Finally, verify that the device is associated with the correct driver by opening the Device
Manager on you PC. When the EB is connected, the “Cebal controlled devices” list contains
“SmartRF05EB”.
If the board is listed as an unknown device or associated with another driver, right click the
device in the Device Manager and select Uninstall. After uninstalling, unplug the board from the
PC and plug it in again. The “Found New Hardware Wizard” should re-appear. Follow the steps
as outlined in the beginning of this section.
21/31
swru318
Q3
How do I measure the current consumption of the CC2543?
A3
The easiest way to measure current consumption of the chip in various modes is to connect the
EM directly to the SmartRF05EB and disconnect everything on the board that consumes power
by removing all jumpers. The jumper on header P13 should not be removed. Connect the
ampere meter between the two terminals on P15. On P10, the jumper for the EM_RESET signal
(connector 35-36) should be mounted. On P1, no jumpers are required, but in order to control
the SoC from a debugger, mount a jumper between 19-20 (DBG_DD) and 21-22 (DBG_DD).
Make sure the RS232 Enable switch is in the “disable” position.
Use SmartRF Studio to set the radio in different modes (RX, TX, etc.), or download an
application on the CC2543 setting the device in the preferred state.
Q4
Can I use another compiler than IAR to develop software for CC2543/44?
A4
Yes, there are several tools available that can be used for CC2543 and CC2544. Any 8051
compiler (e.g. Keil, GCC, and SDCC) can, in theory, be used. Note that these tools may have
limited debugging support for CC2543 and CC2544.

Appendix A
Setting up the Software Environment
This appendix will guide you through the initial steps of setting up a complete software development
environment with IAR Embedded Workbench for 8051. Version 8.10 (and newer) of the tool supports
CC2543 and CC2544 out-of-the-box. In this example we will explain how to set up a project for the
CC2543. The same procedure can be used for the CC2544 by simply replacing all references to
“CC2543” with “CC2544”.
A.1 Create the project
After installing IAR EW8051, start the application. Then select the “Create New Project” under the
Project option.
Select Empty project and click OK. You will now be asked to save the project. Select an appropriate
name for the project and save it. The dialog window will close and the project will be listed in the
“workspace” panel at the left side of the IDE.
24/31
swru318
A.2 Project Options
Right click the project to set up the project options.
A.3 Select Device
In the dialog window that appears, the first thing that is required is to select the device for which the
project is built. Click on the button next to the device field.
25/31
swru318
A new window will appear that allows you to browse through the device configuration files to choose
an appropriate device. Select the CC2543F32 file from the <ew8051_install_dir>\8051\devices\Texas
Instruments folder. This .i51 device description file contains basic information about the chip.
Back in the General Options view, you will see that CC2543 is now the selected device. “CPU core”
should be set to Plain.
A.4 Select Code and Data Model
Next, select code model. Use “Near”.
The default data model for the Near code model is Small. The data model determines how the
compiler & linker use the memory of the 8051 for storage of variables. With the small data model,
variables are typically stored in the DATA memory space. For the large data model, variables are
stored in XDATA. The CC254x User Guide and IAR 8051 C/C++ Compiler Reference Guide have
more information about the various memory spaces. The important thing to remember is that the 8051
core uses different instructions to access the various memory spaces. Access to DATA is, in general,
much quicker than accessing XDATA, but there is normally much more XDATA available than DATA.
For this example, we use Near code model and large data model. The stack can be placed in XDATA.
After setting up the above option, you should have the following settings:
26/31
swru318
A.5 Configure the Linker
Next, you will need to instruct the IDE what linker command file to use. The linker command file
contains information the linker uses in order to place code and variables in ram and flash. Thus, the
linker file must match the flash and ram size of device you are working with. Normally, the linker file
should be tailor-made to an application for optimum performance, but the default command file will
work with most applications.
Use the default configuration file.
27/31
swru318
A.6 Configure the Debugger
Finally, in the debugger section, chose “Texas Instruments” for the Driver.
All the other project options can be left as is and you can close the Project Options dialog by clicking
OK.
28/31
swru318
A.7 Write Software
At this point, the project is configured and you can write your first lines of code. We will show a small
blinking LED example.
In the project, create a new file that you save as blinky.c. Type the following code:
#include <ioCC2543.h>
int main(void)
{
int i;
// Set P1.0 of CC2543 as output
P1DIR |= 0x01;
// Toggle P1.0
for(;;)
{
P1_0 ^= 1;
for(i = 0; i < 10000; i++)
{
asm("NOP");
}
}
}
The code will toggle P1.0 quickly.
Add the file to the project by right clicking the project and selecting Add “blinky.c”.
You are now ready to compile and download the code to the target!
29/31
swru318
A.8 Compile and Debug
Select “Project  Make” from the menu (or press F7) to build the project. The IDE will now compile,
assemble and link the files in the project to generate an executable that can be downloaded to the
target. A message window at the bottom of the screen should show the progress and indicate that the
project was built successfully.
Next, download the application to the target by selecting “Project  Debug” from the menu (or press
Ctrl+D). The application will now be downloaded to the target and you can start stepping through the
code from main.
A.9 Done!
Congratulations! You have just made your first CC2543 software project in IAR.
