VIPER Technical Manual Getting started

Getting started

Depending on the development kit purchased, a Quickstart Manual is provided for

Windows CE, embedded Linux or VxWorks to enable users to set-up and start using the board. Please read the relevant manual and follow the steps defining the set-up of the board. Once you have completed this task you will have a working VIPER system and can start adding further peripherals enabling development to begin.

This section provides a guide to setting up and using of some of the features of the

VIPER. For more detailed information on any aspect of the board see Detailed hardware description , page 18 .

Using the VIPER

Using the CompactFLASH™ socket

The VIPER is fitted with a Type I/II CompactFLASH socket mounted on the topside of the board. The socket is connected to Slot 0 of the PXA255 PC card interface. It supports 3.3V Type I and II CompactFLASH cards for both memory and IO. The VIPER supports hot swap changeover of the cards and notification of card insertion.

RedBoot supports ATA type CompactFlash cards. Files can be read providing the card is formatted with an EXT2 file system. Eboot cannot boot from CompactFlash.

5V CompactFLASH is not supported.

The CompactFLASH card can only be inserted one way into the socket. The correct orientation is for the top of the card, i.e. with the normal printed side face down to the PCB.

Using the serial interfaces (RS232/422/485)

The five serial port interfaces on the VIPER are fully 16550 compatible. Connection to the serial ports is made via a 40-way boxed header. The pin assignment of this header has been arranged to enable 9-way IDC D-Sub plugs to be connected directly to the

cable. See the section PL4 – COMS ports , page 89 , for pin assignment and connector

details.

A suitable cable for COM1 is provided as part of the development kit. The D-Sub connector on this cable is compatible with the standard 9-way connector on a desktop computer.

VL COM4 (RS232) and COM5 (RS422/485) are not available on the standard

VIPER-Lite configuration. Eurotech Ltd can provide custom configurations

(subject to a minimum order quantity) for the VIPER-Lite populated with this

feature. Please contact our Sales team (see Appendix A – Contacting

Eurotech , page 101 ) to discuss your requirements.

Using the audio features

VL

There are four audio interfaces supported on the VIPER: amp out, line out, line in and microphone. The line in, line out and amp interfaces support stereo signals and the microphone provides a mono input. The amplified output is suitable for driving an 8 Ω load with a maximum power output of 250mW per channel. Connections are routed to

PL6 - see the sections Audio (page 56 ) and

PL6 – Audio connector (page 91 ) for

further details.

Using the USB host

VL

The standard USB connector is a 4-way socket, which provides power and data signals to the USB peripheral. The 10-way header PL7 has been designed to be compatible with PC expansion brackets that support two USB sockets. See the

sections USB host interface (page 60 ) and

PL7 – USB connector (page 91 ) for further

details.

Using the USB client

The VIPER board can be used as USB client and connected to a PC via a USB cable.

The USB cable should be plugged into PL17 header. See the sections USB client interface (page 61 ) and

PL17 – USB client connector (page 95 ) for further details.

Using the Ethernet interface

The SMSC LAN91C111 10/100BaseTX Ethernet controller is configured by the

RedBoot bootloader for embedded Linux or VxWorks, and by Eboot for Windows CE.

Connection is made via connector PL1. A second connector PL2 provides activity and

link status outputs for control LEDs. See the sections 10/100BaseTX Ethernet (page

62 ),

PL1 – 10/100BaseTX Ethernet connector (page 87 ) and PL2 – Ethernet status

LEDs connector (page 87 ) for further details.

The Ethernet port may be connected to an ETHER-BREAKOUT module to provide a

standard RJ45 port connector, see section Ethernet breakout board , page

62

for

further details.

VIPER Technical Manual Getting started

Using the PC/104 expansion bus

VL

PC/104 modules can be used with the VIPER to add extra functionality to the system.

This interface supports 8/16 bit ISA bus style peripherals.

Eurotech Ltd has a wide range of PC/104 modules, which are compatible with the

VIPER. These include modules for digital I/O, analogue I/O, motion control, CAN bus, serial interfaces, etc. Please contact the Eurotech Ltd sales team if a particular interface you require does not appear to be available as these modules are in

continuous development. Contact details are provided in Appendix A – Contacting

Eurotech , page 101 .

In order to use a PC/104 board with the VIPER it should be plugged into PL11 for 8-bit

cards and PL11/PL12 for 8/16-bit cards. See the sections PC/104 interface (page 67 )

and PL11 & PL12 – PC/104 connectors (page 94 ) for further details.

The ISA interface on the VIPER does not support DMA or shared interrupts. See the

section Interrupt assignments , page

30

, for details about PC/104 interrupt use.

The VIPER provides +5V to a PC/104 add-on board via the PL11 and PL12 connectors. If a PC/104 add-on board requires a +12V supply, then +12V must be supplied to the VIPER power connector PL16 pin 4. If –12V or –5V are required, these must be supplied directly to the PC/104 add-on board.

The VIPER is available with non-stack through connectors by special order. Contact

Eurotech Ltd (see Appendix A – Contacting Eurotech , page 101 , for more details.
