Blackfin A-V EZ-Extender Manual 1-1 1 A-V EZ-EXTENDER INTERFACES This chapter provides a setup procedure for the Blackfin A-V EZ-Extender and EZ-KIT Lite (ADSP-BF533, ADSP-BF537, or ADSP-BF561). The chapter also describes each evaluation interface the extender supports. The information is presented in the following order. “A-V EZ-Extender Setup” on page 1-2 “Analog Audio Interface” on page 1-3 “Analog Video Interface” on page 1-4 “Camera Module Interfaces” on page 1-4 “Flat Panel Display Interface” on page 1-6 “Example Programs” on page 1-7
A-V EZ-Extender Setup 1-2 Blackfin A-V EZ-Extender Manual A-V EZ-Extender Setup It is very important to set up all components of the system containing the Blackfin A-V EZ-Extender, then apply power to the system. Power your system after these steps are completed: 1. Read the applicable design interface section in this chapter—the text provides an overview of the interface capabilities. 2. Read “System Architecture” on page 2-2 to understand the physical connections of the extender board. For more detailed information, refer to “A-V EZ-Extender Schematic” on page B-1. 3. Set the jumpers on the extender board. Use the block diagram in Figure 2-1 on page 2-3 in conjunction with “Jumpers” on page 2-7. 4. Set the switches and jumpers on the EZ-KIT Lite board. If not already, familiarize yourself with the documentation and schematic drawing of the EZ-KIT Lite (see “Related Documents”). Compare the expansion interface signals of the extender with the EZ-KIT Lite signals to ensure there is no contention. For example, it may be necessary to disable other devices connected to the parallel peripheral interface (PPI) of the processor, change the routing of the PPI clocks, and disable the push buttons. 5. Configure any other interfacing boards; for example, another EZ-Extender or a camera evaluation board.
Blackfin A-V EZ-Extender Manual 1-3 A-V EZ-Extender Interfaces Analog Audio Interface The Blackfin A-V EZ-Extender supports audio applications with the on-board AD1836A multichannel 96 kHz audio codec. The AD1836A codec is a high-performance single-chip device that provides three stereo digital-to-analog converters (outputs) and two stereo analog-to-digital converters (inputs), using Analog Devices patented multibit sigma-delta architecture. The board includes a serial peripheral interface (SPI) port, enabling the processor to adjust volume and other parameters. For a gen- eral overview of the audio interface connections, see Figure 2-1 on page 2-3; for details, see “A-V EZ-Extender Schematic” on page B-1. SPORT0 of the expansion interface connects to the serial port of the AD1836A codec. The processor is capable of transferring data to the audio codec in time-division multiplexed (TDM) mode or I 2S mode. In I2S mode, the codec can operate at a 96 kHz sample rate and allows two channels of output. In TDM mode, the codec can operate at a maximum of 48 kHz sample rate and allows simultaneous use of all input and output channels. To operate in I 2S mode, install the JP7.1/2 jumper. For more information, see “I2S Enable Jumper (JP7.1/2)” on page 2-13. Internal registers of the AD1836A audio codec can be programmed via the SPI port of the processor. (For information on how to program the config- uration registers, refer to the AD1836A data sheet.) The AD1836A codec reset comes from a flag pin located at PPI1_D11 of the expansion interface or from the reset signal on the EZ-KIT Lite. For information on how to configure the reset, see “AV_RESET Source Jumper (JP9.1/3/5)” on page 2-14. Before using the interface, follow the procedure in “A-V EZ-Extender Setup” on page 1-2. For more information about the codec, go to www.analog.com/AD1836A.
Analog Video Interface 1-4 Blackfin A-V EZ-Extender Manual Analog Video Interface The Blackfin A-V EZ-Extender supports video input and output applica- tions with an on-board video encoder and decoder. The ADV7179 video encoder provides up to three output channels of analog video, while the ADV7183B video decoder provides up to three input channels of analog video. Both the encoder and decoder connect to PPI0 of the expansion interface, while the encoder also can connect to PPI1 (if the processor has two PPI ports). For a general overview of the analog video interface con- nectors, see Figure 2-1 on page 2-3; for details, see “AV_RESET Source Jumper (JP9.1/3/5)” on page 2-14. To use ADV7179 and ADV7183B, set up all of the jumpers related to the PPI data signals, frame sync signals, and clock signal. To program the internal register of video devices, configure the 2-wire interface signals (see “TWI Source Selection Jumpers (JP3.3/5/7, JP3.4/6/8)” on page 2-8). Finally, determine the source of encoder or decoder reset, as described in “AV_RESET Source Jumper (JP9.1/3/5)” on page 2-14. Before using the interface, follow the procedure in “A-V EZ-Extender Setup” on page 1-2. For more information about ADV7179 and ADV7183B, go to www.analog.com/ADV7179 and www.analog.com/ADV7183B. Camera Module Interfaces The Blackfin A-V EZ-Extender has three right-angle connectors (J4, J6, and P4) with control signals necessary to interface with three camera eval- uation modules from different manufactures. For a general overview of the camera interface connections, see Figure 2-1 on page 2-3; for details, see “A-V EZ-Extender Schematic” on page B-1. Figure 1-1 shows the orienta- tion of the camera modules as each camera connects to the board.
