PREFACE Thank you for purchasing the Bluetooth EZ-Extender®, Analog Devices, Inc. daughter board to a Blackfin evaluation system with the new expansion interface II (such as the ADSP-BF518F EZ-Board™) or the older STAMP interface (such as the ADSP-BF537 EZ-KIT Lite®). Blackfin processors are embedded processors that support a Media Instruction Set Computing (MISC) architecture.
Product Overview Product Overview The Bluetooth EZ-Extender is a separately sold daughter board that plugs onto an EZ-KIT Lite supporting the STAMP interface or an EZ-Board/EZ-Kit Lite supporting the expansion interface II connector. The extender board isolates the low-level configuration and communication tasks of integrating Bluetooth and radio frequency (RF) wireless technologies in your Blackfin board designs.
Preface All of the power necessary to operate the extender is derived from the mating EZ-KIT Lite/EZ-Board. Before using any of the interfaces, follow the setup procedure in “Bluetooth EZ-Extender Setup” on page 1-4. Purpose of This Manual The Bluetooth EZ-Extender Manual describes operation and configuration of the extender board components. A schematic and a bill of materials are provided for reference.

1 USING BLUETOOTH EZ-EXTENDER This chapter describes the Bluetooth EZ-Extender’s package contents, configuration, installation procedure, and interfaces. The information is presented in the following order. • “Package Contents” on page 1-2 Describes the product’s package contents. • “Bluetooth EZ-Extender Default Configuration” on page 1-3 Describes the board’s default configuration. • “Bluetooth EZ-Extender Setup” on page 1-4 Provides the board’s setup procedure.
• “Expansion Interface” on page 1-6 Describes the board’s expansion interface. • “Example Programs” on page 1-6 Describes the example programs installed with the board’s software. For more information about the mating Blackfin processor, see documents referred to as “Related Documents”. Package Contents Your Bluetooth EZ-Extender package contains one item: the Bluetooth EZ-Extender board.
Bluetooth EZ-Extender Default Configuration The EZ-Extender system contains ESD (electrostatic discharge) sensitive devices. Electrostatic charges readily accumulate on the human body and equipment and can discharge without detection. Permanent damage may occur on devices subjected to high-energy discharges. Proper ESD precautions are recommended to avoid performance degradation or loss of functionality. Store unused EZ-Extender boards in the protective shipping package.
Figure 1-1 shows the default jumper and switch settings, connector locations, and LED used in installation. Confirm that your board is in the default configuration before using the board. Bluetooth EZ-Extender Setup It is important to set up all components of the system containing the Bluetooth EZ-Extender and then apply power to the system. Power on your system after the Bluetooth EZ-Extender has been connected to the EZ-Board or EZ-KIT Lite.
Bluetooth Module The Bluegiga WT12 module is a next-generation, class 2, Bluetooth 2.0 plus EDR module. The WT12 is a highly integrated and sophisticated Bluetooth module, containing all of the necessary elements from Bluetooth radio antenna to a fully implemented protocol stack. Therefore, the WT12 module provides an ideal solution for developers who want to integrate Bluetooth wireless technology into their design with limited knowledge of Bluetooth and RF technologies.
Expansion Interface Expansion interface connectors on top of the Bluetooth EZ-Extender allow other EZ-Extenders to be mounted on top of the Bluetooth EZ-Extender. The UART interface is not brought up to the expansion interface because the interface is used by the WT12 Bluetooth module. All other signals are passed up to the expansion interface from the mating EZ-KIT Lite or EZ-Board through the Bluetooth EZ-Extender.
2 BLUETOOTH EZ-EXTENDER HARDWARE REFERENCE This chapter describes the hardware design of the Bluetooth EZ-Extender. The following topics are covered. • “System Architecture” on page 2-2 Describes the daughter board’s configuration and explains how the board components interface with the processor and EZ-Board. • “Configuration Switch” on page 2-3 Shows the location and describes the board’s configuration switch. • “Jumpers” on page 2-5 Shows the location and describes the board’s jumpers.
System Architecture System Architecture A block diagram of the Bluetooth EZ-Extender is shown in Figure 2-1. Figure 2-1. Bluetooth EZ-Extender Block Diagram The block diagram illustrates how the UART, SPORT, and USB ports are interfaced the Bluetooth module and processor on a mating EZ-KIT Lite/EZ-Board. The block diagram is a high-level diagram and does not show the voltage translation circuitry or the clock buffers. The schematic pages are available in “Bluetooth EZ-Extender Schematic” on page B-1.
Bluetooth EZ-Extender Hardware Reference The board contains a Bluegiga WT12 class 2, a Bluetooth 2.0, and EDR module, described in “Bluetooth Module” on page 1-5. The EZ-Extender is equipped with an I2C serial flash memory chip for data storage and configuration. Configuration Switch This section describes the board’s configuration switch (SW1). The switch location is shown in Figure 2-2. Figure 2-2.
Configuration Switch Positions 7 and 8 of the configuration switch enable or disable UART flow control. Other switch positions are intended for internal Analog Devices test purposes only and not supported. By default, SW1 is all OFF. The switch settings are shown in Table 2-1. Table 2-1. Configuration Switch (SW1) 2-4 SW1 Position UART Flow Control Off UART Flow Control On SW1.1 OFF OFF SW1.2 OFF OFF SW1.3 OFF OFF SW1.4 OFF OFF SW1.5 OFF OFF SW1.6 OFF OFF SW1.7 OFF ON SW1.
Bluetooth EZ-Extender Hardware Reference Jumpers This section describes functionality of the configuration jumpers. Figure 2-3 shows the jumper locations. Figure 2-3.
Jumpers TWI Flash Address Configuration Jumper (JP1) The TWI flash address configuration jumper (JP1) controls the base address of the configuration flash memory. When multiple EZ-Extenders are stacked on top of each other, it may be necessary to change the JP1 setting to avoid any conflict with the configuration flash memory on another EZ-Extender. The default is no jumper installed.
Bluetooth EZ-Extender Hardware Reference Power LED This section describes the power LED (LED1). When LED1 is lit up, it indicates that the board is powered. Figure 2-4 shows the LED location. Figure 2-4.
Connectors Connectors This section describes connector functionality and provides information about mating connectors. The connector locations are shown in Figure 2-5. Dashed lines indicate connectors on the bottom side of the board. Figure 2-5.
Bluetooth EZ-Extender Hardware Reference STAMP UART Connector (J1) The STAMP UART connector (J1) allows the Bluetooth EZ-Extender to be plugged onto an EZ-KIT Lite development board supporting a STAMP interface. The J1 connector is located on the bottom side of the board. For availability and pricing of the connectors, contact Samtec. Refer to “Expansion Interface” on page 1-6 or more information. Part Description Manufacturer Part Number 10-position 0.
Connectors Expansion Interface II Connector (J5) The board-to-board connector (J5) provides signals for the PPI, TWI interfaces and GPIO signals of the mating EZ-Board.
