LCD
The WVGA/LCD EI3 Extender Board is shipped with a NEC 4.1 inch
WVGA (800 x 480) liquid crystal display (LCD) with backlight. All of the
LCD data, touch screen pins, and power pins connect to the display via a
single connector (P5). The 24-bit display connects to the processer via the
processor’s parallel peripheral interface (PPI).
The extender can be configured for 16-bit mode (RGB 565), 18-bit mode
(RGB 666), or 24-bit mode (RGB 888) operation. The configuration is
performed via a software switch (see “LCD Mode Select” on page 2-13)
and “WVGA/LCD EI3 Extender Board Schematic” on page B-1).
The display also uses the serial peripheral interface (SPI) of the processor
for register configurations.
The clock signal used for the LCD can be connected to the on-board
oscillator or generated from the processor (see “PPICLK_DIR Select” on
page 2-13 for more information).
The LCD backlight circuit is controlled via a GPIO signal on the AD7879
touch screen controller.
For more information about the LCD, go to the NEC Web site.
An example program demonstrating capabilities of the LCD is available by
installing the WVGA/LCD EI3 Extender Board BSP.
