Next, the evaluation modules should be plugged in to the SmartRF0
5EB’s and to the SmartRF05BB’s.
A ZigBee sensor demo application is preprogrammed on the CC2530EM’s included in this kit. The
application consists of two different device types; collectors and sensors. 5 of the CC2530EM’s are
programmed as the sensor devic
e type. When running the out of the box demonstration the sensor
EM’s shall be connected to the BB’s. The two EM’s programmed as collector device shall be
connected to the EB’s.
When not using the out of the box demonstration (i.e. the preprogrammed appl
ication) e.g, for RF
evaluation or software development, all of the 7 EM’s can be used equally.
The purpose of the SmartRF05EB is to serve as a general I/O board for testing of the various
peripherals of the CC2530 microcontroller. The SmartRF05EB is also used for programming and
debugging of the CC2530, and has several useful peripheral devices like

5.4
Evaluate the CC2530 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 CC2530. The
application communicates with the
CC2530 via the USB controller
on the SmartRF05EB board. The USB controller uses the debug
interface of the CC2530 to execute commands and to read and write registers.
SmartRF Studio lets you explore the radio on the CC2530, 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 exp
ort function of radio register settings for software
developers.
Before proceeding, please download and install the latest version of SmartRF Studio from the web
[2]
.
By installing Studio, the USB drivers needed for proper interaction between the PC and the hardware
of the CC2530DK will also be installed.
In order to use the SmartRF Studio with CC2530, connect the CC2530EM to the SmartRF05EB. Next,
connect the Smar
tRF05EB 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

Developing your own software with the CC2530
To develop software and debug an application on the CC2530, it is recommended to use IAR
Embedded Workbench. It supports debugging of CC2530 through the SmartRF05EB, so no additional
hardware is required.
IAR EW8051 is bundled with all the required files
for CC2530 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 ZigBee 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 produ
ct. As the owner of a CC2530 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
.

RF Testing
NB! When running RF performance tests, it is rec
ommended 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
5.4
. As described in that chapter, SmartRF Studio can be used to set up
basic tests and tune RF registers accordingly.
Since the CC2530 evaluation board 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. 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

-
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
sign
al generator. Uncalibrated spectrum analyzers can display errors of several dBs.
6.1
TX Parameter Testing Basics
To investigate the TX performance of the CC2530, you can either use a Spectrum Analyzer or an RF
Power Meter.
Use the “Simple TX” test mode in S
martRF 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).

swru209
b
13
/
28
6.2
RX Parameter Testing Basics
To investigate the RX performance of the CC2530, 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
5.3
, can be used for simple sensitivity
measurements with the CC2530EM
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 s
ensitivity
limit of the system.
For more information regarding sensitivity measurements, refer to “Design Note 2
–
Practical
Sensitivity Testing”

CC2531 USB Dongle
The USB dongle that is included in the kit comes preprogrammed such that it can be used together
with the SmartRF Packet Sniffer
[4]
to capture packets going over the air. To use the dongle as a
sniffer, just install the Packet Sniffer PC application (available on the web
[4]
), plug in the USB dongle
and start capturing packets. The Packet Sniffer User Manual
[5]
has more information.
The USB dongle can also be used as
a general development board for USB and RF software. There
is a USB firmware library available from the TI web pages with an implementation of a complete USB
framework, including examples showing both HID and CDC ACM. There is a link to this library on the
CC2530 DK web pages
[14]
.

CC2531 USB Dongle connected to SmartRF05EB
The debug connector on the CC2531 USB Dongle matches the debug connector on the
SmartRF05EB
(and the CC Debugger). Note that, by default, the CC2531 dongle is not powered
through the debug connector, so an external power source must be used while programming. The
easiest solution is to connect it to a USB port on the PC. Alternatively, resistor
R2 can be mounted.
The table below shows the pin out of the debug connector.

SmartRF05 Battery Board
Figure

SmartRF05 Battery Board
The SmartRF05 Battery Board is a smaller and simpler board than the
SmartRF05EB. The Battery
Board can together with an EM be used as a standalone node.
Figure
9
shows the SmartRF05 Battery
Board. The Battery Board is powered with 2 AA
batteries placed in the battery connectors underneath
the board.
The peripherals that are available include 2 push buttons, a joystick with 5 directions and 4 LED’s of
different colours that can be controlled via the EM.
There are 2 switches on the SmartRF05 Battery Board:

The
Power
switch P6 used to switch the board’s power supply on/off.

The
EM selection
switch.
NB: The
EM selection switch
shall be placed in position
SoC/TRX
when using a SoC EM such as
CC2530EM or a transceiver EM is connected to the Battery Board.
The position MSP is used when the CCMSP
-
EM430F2618 board (not part of this kit) is connected. More
information about the
EM Selection switch
is found in section
10.3
.
The following sections give the pin out of the different connectors on the SmartRF05 Battery Board.
Refer to the schematics (in the appendic

Joystick
The joystick detects five positions (centre, up, down, left, right) and one event (pushed). The two
aggregated signals, JOY_MOVE and JOY_LEVEL, are used to detect a joystick event when
using a
SoC (e.g. the CC2530). JOY_MOVE is high whenever the joystick is moved away from the centre
position, including pushing. The other signal, JOY_LEVEL, is a voltage level signal that gives different
values depending on the current position of the jo
ystick. The table below shows these values. Note
that the voltage levels are relative to the voltage on the board.

Voltage on JOY_LEVEL for different joystick positions (T=25
°
C, Vdd=3.0V)
When the EM selection switch is in position MSP, there are 5 discrete signals in addition to
JOY_MOVE and JOY_LEVEL to be used to distinguish which direction the joystick was pressed.
These 5 discrete signals are not used with CC2530
-
only with the CCMSP
-
EM430F2618 board (not
part of this kit). The discrete signals are routed to the EM connectors. See section
10.2
for details.
10.2
EM connectors
The EM connectors P1 a
nd P2 are used to connect an EM to the Battery Board. The pin out for these
connectors is shown below.
Table
1
in section
7
gives information about how the signals of the EM
connectors are connected to the CC2530 on the EM board.
Note that some of the signals are shared, e.g.
IO_LED4_SOC/IO_BUTTON1. This means that the
signal is shared between IO’s on the board; in this case both LED 4 when in SoC mode and Button 1.
Pressing Button 1 will affect the state of LED 4. Similarly, if a SoC is toggling LED 4, it cannot read
from Butt
on 1 at the same time.

EM Selection Switch
The EM selection switch on SmartRF05BB controls a multiplexer on the board that allows either a
connected RF SoC EM or
an MSP430 add
-
on board to access all four LEDs on the evaluation board.
The limitation was caused by the particular pin
-
out on the RF evaluation modules that needed to be
backwards compatible with other boards and test equipment.

EM Selection Switch (P8)
The switch will both affect the operation of the LEDs and Button 1.
NB: The
EM Selection
switch shall be placed in position SoC/TRX when the CC2530EM is used with
SmartRF05BB.
