Product Overview
The WVGA/LCD EI3 Extender Board is a separately sold daughter board
that plugs onto the IE3 of an EZ-KIT Lite/EZ-Board evaluation system.
The extender board aids the design and prototyping phases of embedded
processor-targeted applications.
The board extends the capabilities of the evaluation system by providing a
connection between the parallel peripheral interface (PPI) of the processor
and on-board 4.1 inch liquid crystal display (LCD). The serial peripheral
interface (SPI) and two-wire interface (TWI) of the processor are used to
communicate with the LCD, AD7879 touch screen controller, AD7147
capacitive touch controller, and ADXL345 digital accelerometer on the
extender.
