1. Introduction
This document illustrates how to build Realtek low power Wi-Fi software under IAR SDK
environment.
2. How to get IAR
IAR provides an IDE environment for code building, downloading, and debugging. Please check
“IAR Embedded Workbench” on http://www.iar.com/, and trail version is available. It requires IAR
version greater than v7.20 which supports CMSIS-DAP.
3. Debugger Setting
This board supports both CMSIS-DAP debugger and J-Link.
3.2 CMSIS-DAP
Ameba Device Board 2V0 supports CMSIS-DAP debugger. It requires installing “serial to USB driver”
at first. Serial to USB driver can be found in tools\serial_to_usb\mbedWinSerial_16466.
Connect board to the PC with micro-USB cable.

UM0023
After installation, connect the board to PC, and then there should be mbed Serial Port shown in
Device Manager.
3.2 J-Link/JTAG
The board is configured as CMSIS-DAP mode. To use J-Link debugger, please follow the next
procedures.
Hardware Configuration
Weld JTAG and log UART connectors to HDK board and connect with pitch 2.54mm 2x5pins
connector. It is recommended to weld the connector on the bottom side.
p.s. J-Link is supported on RTL-AMEBA_DEV_3V0

2.54mm 2x5pins connector (or use Dupont Line)
IAR Setting
Change setting of IAR project from CMSIS-DAP to J-Link/J-Trace in
Project Options Debugger Setup Driver, and Selecting OK to finish and enjoy JTAG
debugging.

5. How to use sample code
There are several peripheral example code under folder “project\project_name_xxxx\
example_sources \”, you can copy & paste the example’s “inc” and “src” to project folder.
Ex. To use i2c example code, you can copy “src” and “inc” from
“project\project_name_xxxx\example_sources\i2c\”.
Ameba API follows mbed API. User can check mbed website for peripheral API.

6. Warning
6.1 Federal Communication Commission Interference Statement
This equipment has been tested and found to comply with the limits for a Class B digital
device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable
protection against harmful interference in a residential installation. This equipment generates,
uses and can radiate radio frequency energy and, if not installed and used in accordance with the
instructions, may cause harmful interference to radio communications. However, there is no
guarantee that interference will not occur in a particular installation. If this equipment does
cause harmful interference to radio or television reception, which can be determined by turning
the equipment off and on, the user is encouraged to try to correct the interference by one of the
following measures:
Reorient or relocate the receiving antenna.
Increase the separation between the equipment and receiver.
Connect the equipment into an outlet on a circuit different from that
to which the receiver is connected.
Consult the dealer or an experienced radio/TV technician for help.
This device complies with Part 15 of the FCC Rules. Operation is subject to the following two
conditions: (1) This device may not cause harmful interference, and (2) this device must accept any
interference received, including interference that may cause undesired operation.
FCC Caution: Any changes or modifications not expressly approved by the party responsible for
compliance could void the user's authority to operate this equipment.
IMPORTANT NOTE:
FCC Radiation Exposure Statement:
This equipment complies with FCC radiation exposure limits set forth for an uncontrolled
environment. This equipment should be installed and operated with minimum distance 20cm
between the radiator & your body.
IEEE 802.11b or 802.11g operation of this product in the U.S.A. is firmware-limited to channels 1
through 13.
This device and its antenna(s) must not be co-located with any other transmitters except in
accordance with FCC multi-transmitter product procedures.
Refering to the multi-transmitter policy, multiple-transmitter(s) and module(s) can be operated
simultaneously without C2PC.
This module is intended for OEM integrator. The OEM integrator is responsible for the compliance
to all the rules that apply to the product into which this certified RF module is integrated.
Additional testing and certification may be necessary when multiple modules are used.
USERS MANUAL OF THE END PRODUCT:
2015-07-21

In the users manual of the end product, the end user has to be informed to keep at least 20cm
separation with the antenna while this end product is installed and operated. The end user has to
be informed that the FCC radio-frequency exposure guidelines for an uncontrolled environment
can be satisfied. The end user has to also be informed that any changes or modifications not
expressly approved by the manufacturer could void the user's authority to operate this equipment.
If the size of the end product is smaller than 8x10cm, then additional FCC part 15.19 statement is
required to be available in the users manual: This device complies with Part 15 of FCC rules.
Operation is subject to the following two conditions: (1) this device may not cause harmful
interference and (2) this device must accept any interference received, including interference that
