Analog Devices ADSP-21369 system manual Elvis Interface

ELVIS Interface

The SPI flash memory connects to the SPI port of the processor and designates:

•DPI pin 5 (DPI5) as a chip select

•DPI pin 3 (DPI3) as the SPI clock

•DPI pin 1 (DPI1) as the MOSI

•DPI pin 2 (DPI2) as the MISO.

By default, the DPI is setup for the SPI flash, and any required changes to the SPI flash can be made by modifying the DPI of the processor. An example program is included in the EZ-KIT Lite installation directory to demonstrate how to read and write to the SPI flash memory.

The asynchronous SRAM memory and the parallel flash memory connect to the asynchronous memory controller of the processor. Each of their respective memory banks can be independently programmed with differ- ent timing parameters. For more information on changing wait states to speed up or slow down the asynchronous controller and other setup infor- mation, refer to the ADSP-2136x SHARC Processor Hardware Reference for ADSP-21367/8/9 Processors. Example programs are included in the EZ-KIT Lite installation directory to demonstrate how to read and write to the SRAM or flash memory.

The ADSP-21369 EZ-KIT Lite board contains the National Instruments Educational Laboratory Virtual Instrumentation Suite interface. The interface features the DC voltage and current measurement modules, oscilloscope and bode analyzer modules, function generator, arbitrary waveform generator, and digital IO.
