standoff on the bottom side of the board. Insert the plastic spacers between the bottom side of the EZ-KIT Lite/EZ-Board and to the top side of the extender.

3. Connect the EZ-KIT Lite/EZ-Board to a personal computer (PC) running CCES with the product BSP. Refer to the EZ-KIT Lite/EZ-Board manual for instructions.

LCDThe 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.



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 gen-erates 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 “AD7879 PENIRQ Signal” and “AD7879 SPI Chip Select” on page 2-14 for details.

For more information about the AD7879 touch controller, go to www.ana-log.com and search for AD7879.

An example program demonstrating capabilities of the touch controller is available by installing the product BSP.

Capacitive Touch Controller (AD7147)The WVGA/LCD EI3 Extender Board is equipped with an Analog

Devices CapTouch® programmable controller (AD7147) for applications implementing push buttons and scroll wheels. The four push button sen-sors and one scroll wheel are located on the top side of the extender’s printed circuit board (PCB).

The AD7147 controller generates an interrupt request for the processor whenever a user touches the push button or the scroll wheel. The two-wire interface (TWI) is used for communications between the controller and



Digital Accelerometer (ADXL345)


processor. The push buttons and scroll wheel are copper pads on the PCB. Touch the respective button or traverse around the wheel with a finger to enable sensor pads and generate an interrupt request. An interrupt signal from the controller is connected to a GPIO signal on the processor. The GPIO signal is configured via a software switch. Refer to “AD7147 Inter-rupt Signal” for more information.

For more information about the AD7147 capacitive touch controller, go to www.analog.com and search for AD7147.

An example program demonstrating capabilities of the touch controller is available by installing the product BSP.

Digital Accelerometer (ADXL345)The WVGA/LCD EI3 Extender Board is equipped with an Analog Devices 3-axis accelerometer (ADXL345) with high-resolution (13-bit) measurement at up to +/- 16g. Digital output data is formatted as 16-bit twos complement and accessible through SPI or TWI.

Two interrupt signals from the ADXL345 accelerometer are connected to two GPIO signal of the processor. The GPIO signals are configured via a software switch (see “ADXL345 Interrupt Signals”). The SPI port or the TWI port is used for communications between the controller and proces-sor; see “ADXL345 TWI/SPI Mode Select” for more information. The SPI signals are configured via software as described in “ADXL345 SPI Chip Select”. Refer to “WVGA/LCD EI3 Extender Board Schematic” on page B-1 for more information.

For more information about the ADXL345 accelerometer, go to www.ana-log.com and search for ADXl345.

An example program demonstrating capabilities of the accelerometer is available by installing the product BSP.






Expansion Interface IIIThe 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 periph-erals 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 sepa-rate 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.

Analog Devices does not support and is not responsible for the effects of additional circuitry.

WVGA/LCD EI3 Extender Board Hardware Reference

Software-Controlled Switches (SoftConfig)

On the WVGA/LCD EI3 Extender Board, all of the traditional mechani-cal switches and jumpers have been replaced by I2C software-controlled switches. Refer to any SoftConfig*.c file found in the installation direc-tory 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.

Care should be taken when changing SoftConfig settings not to create a conflict between interfaces. The same GPIO signal and SPICS should not be configured for more than one interface.

Overview of SoftConfigIn order to further clarify the use of electronic single FET switches and multi-channel bus switches, an example of each is illustrated and com-pared 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



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 2-3 shows the equivalent circuit to Figure 2-2 but utilizes mechan-ical 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.

Figure 2-2. Example of Individual FET Switches



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 mechan-ical 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 refer-ence 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.

Programming SoftConfig on the WVGA/LCD EI3 Extender Board

On the WVGA/LCD EI3 Extender Board, a single Xilinx XC2C256 com-plex programmable logic device (CPLD) controls individual and

Figure 2-5. Example of Mechanical Switch Equivalent to Figure 2-4



electronic bus switches via TWI. The device has the following program-ming characteristics:

• There are seven programmable GPIO registers.

• Each GPIO register controls eight signals (software switches).

• By default, the GPIO signals function as input signals; therefore, all electronic switches are in the OFF state.

The signals must be programmed as output signals to override their default values. The following table shows the register addresses and values that must be written to them to program the signals as out-put signals.

Each of the examples in the BSP includes source files that program the soft switches, even if the default settings are being used. The README for each example identifies only the signals that are being changed from their default values. The code that programs the soft switches is located in the SoftConfig_LCD.c file in each example.

Page 2 of “WVGA/LCD EI3 Extender Board Schematic” on page B-1 shows how the GPIO expander is connected to the board’s ICs.

U14–16 are 24-bit bus switches. The switches select how the LCD module is connected to the processor. You can select a 16-, 18-, or 24-bit interface.

U31–41 are 2-port bus switches. The switches select the GPIO signals to be used as interrupts and SPICS signals to connect to various IC on the extender.

The U44–45 switches select the interface to communicate with the acceler-ometer: SPI or TWI.

Table 2-1 through Table 2-6 show the output signals of the GPIO expander (U10) with a TWI address of 0100 111X, where X represents the read or write bit. The signals that control an individual FET have an entry

LCD SPI Chip SelectThe 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 SelectThe PPICLK_DIR select switch determines whether the LCD clock is gener-ated 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 trans-ceiver. 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 pro-cessor’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 sup-ported. 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 appro-priate bus switch (U14–16).

AD7879 PENIRQ SignalThe 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.

AD7879 SPI Chip SelectThe 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 appro-priate SPICS signal via the U39 bus switch.

AD7147 Interrupt SignalThe 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 SignalsThe 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 SelectThe ADXL345 TWI/SPI mode select pin configures the interface con-nected 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.



ADXL345 SPI Chip SelectThe ADXL345 SPICS pin connects the chip select pin of the SPI of the ADXL345 accelerometer to one of three SPI select pins of the processor. U10 ports GPF0, GPF1, and GPF2 select the connection to the appropriate SPICS signal via the U32 bus switch.

Connectors


ConnectorsThis section describes connector functionality and provides information about mating connectors. The connector locations are shown in Figure 2-6.

Figure 2-6. Connector Locations



Expansion Interface III (EI3) Connectors (J1–2)Two board-to-board connectors (J1 and J2) provide signals from the SPI, TWI, UART, SPORT, and GPIO interfaces of the processor. The con-nectors are located on the top side of the board. For more information, see “Expansion Interface III” on page 1-7.

Expansion Interface III (EI3) Connectors (P1–2)Two board-to-board connectors (P1 and P2) provide signals from the SPI, TWI, UART, SPORT, and GPIO interfaces of the processor. The con-nectors are located on the bottom side of the board and used when stacking another board under the extender board. For more information, see “Expansion Interface III” on page 1-7.

Power Connector (P4)

By design, the extender board derives its power from the EZ-KIT Lite/EZ-Board. If the EZ-KIT Lite/EZ-Board is not able to supply enough power to the extender, an external power supply can be connected to the extender via P4.
