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
