1 USING WVGA/LCD EI3 EXTENDER BOARD This chapter provides the setup procedure for the WVGA/LCD EI3 Extender Board and evaluation board and describes the interfaces the extender supports. The information is presented in the following order.
Package Contents Package Contents Your WVGA/LCD EI3 Extender Board package contains the following items. • WVGA/LCD EI3 extender board • A bag containing hardware for securing the extender board onto the EZ-KIT Lite/EZ-Board • Release notes containing information about the product download Contact the vendor where you purchased your extender board or contact Analog Devices, Inc. if any item is missing.
Using WVGA/LCD EI3 Extender Board System Requirements Verify that your PC has these minimum requirements for the CCES installation: • 2 GHz single-core processor • 1 GB RAM • 8 GB available disk space • One open USB port A faster disk drive decreases the build time, especially for a large amount of source files. Extender Board Installation Follow these instructions to ensure correct operation of the product hardware and software. 1. Attach the extender board to the EZ-KIT Lite/EZ-Board.
LCD 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. 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.
Using WVGA/LCD EI3 Extender Board 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.
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 Interrupt Signal” for more information. For more information about the AD7147 capacitive touch controller, go to www.
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.
Board Design Database Studio. Once installed, the example programs can be found in the \WVGA_LCD_EI3_Extender_Board-RelX.X.X\WVGA_LCD_EI3 directory where X.X.X denotes the support package release number. Board Design Database A .zip file containing all of the electronic information required for the design, layout, fabrication and assembly of the product is available for download from the Analog Devices board design database at: http://www.analog.
2 WVGA/LCD EI3 EXTENDER BOARD HARDWARE REFERENCE This chapter describes the hardware design of the WVGA/LCD EI3 Extender Board. The following topics are covered. • “System Architecture” on page 2-2 Describes the board’s configuration and explains how the board components interface with the processor. • “Software-Controlled Switches (SoftConfig)” on page 2-3 List and describe signals routed through the software-controlled switches. • “Connectors” on page 2-16 Describes the on-board connectors.
System Architecture System Architecture A block diagram of the WVGA/LCD EI3 Extender Board is shown in Figure 2-1. EPPI SPI GPIO TWI Back Light Bus Transceiver 3.
WVGA/LCD EI3 Extender Board Hardware Reference 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.
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.
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.

Software-Controlled Switches (SoftConfig) electronic bus switches via TWI. The device has the following programming characteristics: • There are seven programmable GPIO registers. GPIO Register Register Address GPIOA 0x03 GPIOB 0x05 GPIOC 0x07 GPIOD 0x09 GPIOE 0x0b GPIOF 0x0d GPIOG 0x0f • 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.
WVGA/LCD EI3 Extender Board Hardware Reference IODIR Register IODIR Register Address Value to be Written to Program Signals as Outputs IODIRF 0x0c 0 IODIRG 0x0e 0 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.
