LCD Touch Controller (AD7879)
The WVGA/LCD EI3 Extender Board is equipped with an Analog
Devices resistive touch controller (AD7879). The AD7879 controller is
connected to the LCD touch screen via four pins (X+, X-, Y+, Y-). You
can access the controller via the SPI of the processor. The controller generates an interrupt request for the processor whenever the user touches the
LCD. The processor uses the SPI to read the appropriate registers on the
controller.
An interrupt signal from the AD7879 controller is connected to a GPIO
signal of the processor. The GPIO signal is configured via a software
switch. The SPI is used for communications between the controller and
processor; the SPI signals are configured via software as well. Refer to

WVGA/LCD EI3 Extender Board Manual
Using WVGA/LCD EI3 Extender Board
Expansion Interface III
The Expansion Interface III (EI3) allows an extender board to be used
across various hardware platforms that have the same expansion interface
connectors.
The EI3 implemented on the WVGA/LCD EI3 Extender Board contains
the PPI, SPI, TWI and GPIO ports. These signals are used for the peripherals on the extender. Signals that are not used on the extender are passed
through to two connectors on the bottom side of the board (P1 and P2)
and can be used for stacking another EI3 extender board. The connectors
contain a majority of the processor’s signals. For pinout information, go
to “WVGA/LCD EI3 Extender Board Schematic” on page B-1. The
mechanical dimensions of the expansion connectors can be obtained by
contacting “Technical Support”.
For more information about extender boards, visit the Analog Devices
Web site (www.analog.com).
Limits to current and interface speed must be taken into consideration
when using the EI3. Current for the EI3 can be sourced from the EZ-KIT
Lite/EZ-Board; therefore, the current should be limited to 200 mA for 5V
and 300 mA for the 3.3V planes. If more current is required, then a separate power connector and a regulator must be designed on the daughter
card. Additional circuitry can add extra loading to signals, decreasing their
maximum effective speed.
Devices does not support and is not responsible for the
 Analog
effects of additional circuitry.

Software-Controlled Switches
(SoftConfig)
On the WVGA/LCD EI3 Extender Board, all of the traditional mechanical switches and jumpers have been replaced by I2C software-controlled
switches. Refer to any SoftConfig*.c file found in the installation directory of CCES for an example of how to set up the SoftConfig features of
the product through software.
The SoftConfig section of this manual serves as a reference to any user
that intends to modify an existing software example. If software provided
by ADI is used, there should be little need to reference this section.
should be taken when changing SoftConfig settings not to
 Care
create a conflict between interfaces. The same GPIO signal and
SPICS should not be configured for more than one interface.
Overview of SoftConfig
In order to further clarify the use of electronic single FET switches and
multi-channel bus switches, an example of each is illustrated and compared to a traditional mechanical switching solution. This is a generic
example. After the generic discussion, there is a detailed explanation of the
SoftConfig interface specific to the extender board.
Figure 2-2 shows two individual FET switches (Pericom PI3A125CEX)
with reference designators UA and UB. Net names ENABLE_A and ENABLE_B
control UA and UB. In this example, the default FET switch enable settings
are controlled by resistors RA and RB which pull the enable pin 1 of UA and
UB to ground (low). In a real example, these enable signals are controlled
by the Microchip IO expander. The default pull-down resistors connects
the signals EXAMPLE_SIGNAL_A and EXAMPLE_SIGNAL_B and also connects
signals EXAMPLE_SIGNAL_C and EXAMPLE_SIGNAL_D. To disconnect
EXAMPLE_SIGNAL_A from EXAMPLE_SIGNAL_B, the Microchip IO expander is

Software-Controlled Switches (SoftConfig)
used to change ENABLE_A to a logic 1 through software that interfaces with
the Microchip. The same procedure for ENABLE_B disconnects
EXAMPLE_SIGNAL_C from EXAMPLE_SIGNAL_D.
Figure 2-2. Example of Individual FET Switches
Figure 2-3 shows the equivalent circuit to Figure 2-2 but utilizes mechanical switches that are in the same package. The default is shown by black
boxes located closer to the ON label of the switches. In order to disconnect
these switches, physically move the switch to the OFF position.

WVGA/LCD EI3 Extender Board Manual
WVGA/LCD EI3 Extender Board Hardware Reference
Figure 2-3. Example of Mechanical Switch Equivalent to Figure 2-2
Figure 2-4 shows a bus switch example, reference designator UC (Pericom
PI3LVD512ZHE), selecting between lettered functionality and numbered
functionality. The signals on the left side are multiplexed signals with
naming convention letter_number. The right side of the circuit shows the
signals separated into letter and number, with the number on the lower
group (eg. 0B1) and the letter on the upper group (eg. 0B2). The default
setting is controlled by the signal CONTROL_LETTER_NUMBER which is pulled
low. This selects the number signals on the right to be connected to the
multiplexed signals on the left by default. In this example, the Microchip
IO expander is not shown but controls the signal CONTROL_LETTER_NUMBER
and allows the user to change the selection through software.
Figure 2-5 shows the equivalent circuit to Figure 2-4 but utilizes mechanical switches. Notice the default for reference designators SWC and SWD is
illustrated by black boxes located closer to the ON label of the switches to
enable the number signals by default. Note the default setting for reference designators SWE and SWF is OFF. In order to connect the letters instead
of the numbers, the user physically changes all switches on SWC and SWD to
the OFF position and all switches on SWE and SEF to the ON position.

LCD SPI Chip Select
The LCD SPICS switch connects the chip select pin of the serial peripheral
interconnect interface (SPI) of the LCD to one of three SPI select pins of
the processor. U10 ports GPE3, GPE4, and GPE5 select the connection to the
appropriate SPICS signal via the U31 bus switch.
PPICLK_DIR Select
The PPICLK_DIR select switch determines whether the LCD clock is generated by an on-board oscillator or by the processor. By driving the
PPICLK_DIR signal (U10 port GPE7) high, the on-board oscillator is enabled
and driven to the LCD and processor via the U1 dual-supply bus transceiver. By driving the PPICLK_DIR signal low, the on-board oscillator is
disabled, and the clock from the processor is driven to the LCD via the U1
dual-supply bus transceiver.
LCD Mode Select
The LCD mode select switch determines whether the interface to the processor’s PPI is 16, 18, or 24 bits. In 16-bit mode, RGB565 is supported.
In 18-bit mode, RGB666 is supported. In 24-bit mode, RGB888 is supported. The LCD mode is selected by driving low the 24_BIT_LCD_MODE
(U10 port GPF5), 18_BIT_LCD_MODE (U10 port GPF6), or 16_BIT_LCD_MODE
(U10 port GPF7) signal. Driving one of these signals low enables the appropriate bus switch (U14–16).
AD7879 PENIRQ Signal
The AD7879 PENIRQ switch connects the interrupt signal of the AD7879
touch screen controller to one of eight GPIO pins of the processor. U10
ports GPA0–7 select the connection to the appropriate GPIO signal via the
U40 and U41 bus switches.
WVGA/LCD EI3 Extender Board Manual

Software-Controlled Switches (SoftConfig)
AD7879 SPI Chip Select
The AD7879 SPICS connects the chip select pin of the SPI of the AD7879
touch screen controller to one of three SPI select pins of the processor. U10
ports GPE0, GPE1, and GPE2 are used to select the connection to the appropriate SPICS signal via the U39 bus switch.
AD7147 Interrupt Signal
The AD7147 INT signal connects the interrupt signal of the AD7147
touch controller to one of eight GPIO pins of the processor. U10 ports
GPB0–7 select the connection to the appropriate GPIO signal via the U37
and U38 bus switches.
ADXL345 Interrupt Signals
The ADXL345 INT1 and INT2 connect the interrupt signals of the
ADXL345 accelerometer to one of eight GPIO pins of the processor. U10
ports GPC0–7 and GPD0–7 select the connection to the appropriate GPIO
signal via the U33–36 bus switch.
ADXL345 TWI/SPI Mode Select
The ADXL345 TWI/SPI mode select pin configures the interface connected to the ADXL345 accelerometer. When the accelerometer’s
interface is configured for SPI, the appropriate SPICS must also be
configured.
To configure the ADXL345 accelerometer for operating in SPI mode, the
~ADXL345_SPI_MODE signal ( U10 port GPF3) is driven low to enable the U45
bus switch.
To configure the ADXL345 accelerometer for operating in TWI mode,
the ~ADXL345_TWI_MODE signal (U10 port GPF4) is driven high to enable the
U44 TWI switch.
