Regulatory Compliance The Blackfin Landscape LCD EZ-Extender is designed to be used solely in a laboratory environment. The board is not intended for use as a con- sumer end product or as a portion of a consumer end product. The board is an open system design which does not include a shielded enclosure and therefore may cause interference to other electrical devices in close prox- imity. This board should not be used in or near any medical equipment or RF devices. The Blackfin Landscape LCD EZ-Extender is currently being processed for certification that it complies with the essential requirements of the European EMC directive 89/336/EEC amended by 93/68/EEC and therefore carries the “CE” mark. The Blackfin Landscape LCD EZ-Extender contains ESD (electrostatic dis- charge) sensitive devices. Electrostatic charges readily accumulate on the human body and equipment and can discharge without detection. Perma- nent damage may occur on devices subjected to high-energy discharges. Proper ESD precautions are recommended to avoid performance degrada- tion or loss of functionality. Store unused extender boards in the protective shipping package.

Blackfin Landscape LCD EZ-Extender Manual ix PREFACE Thank you for purchasing the Blackfin® Landscape LCD EZ-Extender®, Analog Devices, Inc. extender board to the EZ-KIT Lite®/EZ-Board® evaluation system for the ADSP-BF526, ADSP-BF537, ADSP-BF538, and ADSP-BF548 Blackfin processors. Blackfin processors are embedded processors that support a Media Instruction Set Computing (MISC) architecture. This architecture is the natural merging of RISC, media functions, and digital signal processing characteristics towards delivering signal processing performance in a microprocessor-like environment. EZ-KIT Lites and Landscape LCD EZ-Extenders are designed to be used in conjunction with the CrossCore ® Embedded Studio (CCES) and Visu- alDSP++® software development environments. The development environment facilitates advanced application code development and debug, such as: Create, compile, assemble, and link application programs written in C++, C, and Landscape LCD EZ-Extender assembly Load, run, step, halt, and set breakpoints in application programs Read and write data and program memory Read and write core and peripheral registers Plot memory To learn more about Analog Devices development software, go to http://www.analog.com/processors/tools.
Product Overview x Blackfin Landscape LCD EZ-Extender Manual Product Overview The Blackfin Landscape LCD EZ-Extender is a separately sold daughter board that plugs onto the expansion interface II of the ADSP-BF526 EZ-Board. The extender also plugs into the parallel peripheral interface (PPI) connector of the ADSP-BF537, ADSP-BF538, or ADSP-BF548 EZ-KIT Lite evaluation system. The extender board aids the design and prototyping phases of the ADSP-BF526, ADSP-BF537, ADSP-BF538, or ADSP-BF548 processor targeted applications. Please visit www.analog.com/EX2-LLCD for additional information, includ- ing CCES support. The board extends the capabilities of the evaluation system by providing a connection between the PPI of the Blackfin processor and the on-board 3.5 in. LCD display. The serial peripheral interconnect (SPI) port and TWI interface of the Blackfin processor are used to communicate to the LCD display, AD7879 touch screen controller, AD7147 capacitive touch controller, and the 2 KB serial ROM of the extender. The following is a list of the Blackfin Landscape LCD EZ-Extender interfaces. LCD display with touch capabilities: Sharp LQ035Q1DH02 3.5 in. LCD with resistive touch 320 (horizontal) x 240 (vertical) landscape 1.8V to 3.6V I/O operation LCD backlight LCD touch controller: Analog Devices AD7879 touchscreen controller 1.8V to 3.3V I/O operation
