2 Getting Started
2.1 Evaluation Systems
Bitsy boards are shipped as evaluation systems designed to get the developer up and running
quickly.
To use the system, simply plug power supply into the mini DIN-8 receptacle on the system.
If the screen does not display anything after five to ten seconds, check the Frequently Asked
Questions, below. Most operating systems cold boot within twenty seconds.
An evaluation system consists of the following:
• Bitsy single-board computer
• Bitsy Compact Flash Connector Board
• Flat panel display and cable
• Backlight inverter and cable
• Touch screen and cable
• 120VAC power supply
• Plexiglas mounting
• Developer's Cable Kit including
• Serial Port DB9 adapter (ADS cable #610111-80001)
• DB9F/F null modem cable
• Operating system of your choice
• User's Guide (this document and operating system guide)
• Information about how to access ADS technical resources for the operating system you
have chosen.
Make sure you have received all the components before you begin your development.
2.2 Frequently Asked Questions
The following are some of the most commonly asked questions for evaluation systems:
Q: When I turn on power, my screen is white and nothing comes up on it.
A: Check the connector seating. The flat panel connector may have come loose in shipping.
Press it firmly into the panel and reapply power to your system.
Q: Do I have to turn off the system before I insert a PCMCIA or compact flash card?
A: No. The Bitsy supports hot-swapping of PCMCIA and compact flash cards. Consult the
operating system documentation for details.
Q: Do I need to observe any ESD precautions when working with the system?
A: Yes. If possible, work on a grounded anti-static mat. At a minimum, touch an electrically
grounded object before handling the board or touching any components on the board.
Q: What do I need to start developing my application for the system?
A: You will need a flash ATA card (8MB or larger) and the cables supplied with your system to
interface your development station to the system. For further direction, consult the ADS guide for
the installed operating system.

Bitsy User’s Manual
Page 6 ADS document # 110111-1003A
Q: Who can I call if I need help developing my application?
A: ADS provides technical support to get your development system running. For customers who
establish a business relationship with ADS, we provide support to develop applications and
drivers.
Q: Is there online support?
A: Yes. Information about the Bitsy hardware (such as this manual) is available on the ADS
product page. ADS has operating-system-specific sites to support its customers. You should have
received information about ADS's developers' web site for the operating system you have selected.
Q: Can I upgrade the version of the operating system?
A: Yes. ADS provides regular operating system updates on its developers' web site. For
operating systems not maintained by ADS, contact the operating system vendor.
Q: I would like to interface to a different display panel. How can I do this?
A: ADS may have already interfaced to the panel you are interested in. Consult ADS for
availability. ADS can interface to just about any panel you provide.
2.3 Organization of this Manual
The manual organizes information in three key sections:
Introduction Provides an overview of the functionality and organization of the Bitsy.
Hardware Reference Describes the configuration settings and connector pinouts for all
systems of the Bitsy.
System Integration Provides key information about power management, tips for system
integration and electrical and mechanical interface specifications.
To locate the information you need, try the following:
1. Browse the Table of Contents. Section titles include connector designators and their
function.
2. Follow cross-references between sections.
3. View and search this manual in PDF format
2.4 For Further Information...
ADS maintains a web site exclusively for its developers. The site includes downloads,
troubleshooting guides, operating system updates and the "ADS Knowledge Base", a
comprehensive document with dozens of questions answered about developing applications for
ADS products. Instructions on how to access the site are shipped with every evaluation system.

ADS document # 110111-1003A Page 7
3 Hardware Reference
This section gives an overview of the hardware features of the Bitsy. This overview includes a
description of the switches, jumper settings, connectors and connector pinouts.
3.1 Locating "Pin 1"
Many connectors and headers have a visible number on the board that indicates pin 1. If that pin
is not clearly marked, there are two other ways to locate pin 1:
1. The easiest method is to look at the underside of the board. The square pad is pin 1.
2. You can determine pin 1 from the mechanical drawing provided in section 4.2.
3.2 Switches
3.2.1 S1: DIP Switch
S1 is a four-position DIP switch. It connects to the system/interrupt controller. The settings of
some individual switches can be read from the SA1111 I/O, others are available for off board use.
Some operating systems on the Bitsy reserve these switches for their use. Consult the operating
system manual for details.
3.3 ADSmartIOTM
ADSmartIOTM is a second RISC microcontroller on the Bitsy. This device provides additional I/O
functionality for specialized tasks. Your application software can configure the standard
ADSmartIOTM firmware for a variety of functions, including digital I/O, PWM, A/D, keypad and
PS/2 keyboard operation.
3.4 Onboard LEDs
The Bitsy has one onboard LED mapped as follows:
Signal GPIO line Part Designator Color
LED0 20 D3 Green
3.5 Jumper Settings
Jumpers on the Bitsy select a variety of operational options. All use 2mm shorting blocks (shunts)
to select settings. Make sure power is turned off to the Bitsy when changing the position of a
shunt.
3.5.1 JP1, JP2: VEE Contrast Voltage Control
Type: 2-post header, 2mm
These jumpers are used when configuring the VEE voltage between a positive output and a
negative output.
JP1,2 Jumper setting Voltage Selected
1-2 Negative VEE
2-3 Positive VEE

Bitsy User’s Manual
Page 8 ADS document # 110111-1003A
3.5.2 JP3: Flat Panel Voltage Select
This jumper selects the supply voltage for the flat panel.
Jumper setting Voltage Selected
1-2 3.3 V
2-3 5.0 V
WARNING! Make sure you have selected the correct voltage before connecting the panel. Flat
panels are notoriously sensitive to--and are often irreparably damaged by--incorrect voltages.
3.5.3 JP4: Flat Panel Data Voltage Select
Type: 3-post header, 2mm
This jumper selects the voltage of the data signals for the flat panel display.
Important: These jumpers are set at the factory and cannot be changed by the user. Damage to the
panel drivers may occur if this jumper setting is changed.
Hint: Some 5V panels will run correctly with 3.3V data.
Jumper setting Voltage Selected
1-2 3.3 V
2-3 5.0 V
3.5.4 J7: Flat Panel VEE Select
Type: 4-post header, 2mm
This jumper selects the VEE voltage for the flat panel. Note that VEE is installed only as an
option and is not installed on all Bitsy boards.
Jumper setting Voltage Selected
none none
1-3, 2-4 Positive VEE
1-2, 3-4 Negative VEE
WARNING! Make sure you have selected the correct voltage before connecting the panel. Flat
panels are sensitive to--and are often irreparably damaged by--incorrect voltages.
3.6 Connector Pinouts
The following tables describe connector pinouts and the type of connector. At least one pin of
every connector is labeled on the Bitsy. Double-row headers on the board are
all numbered as shown in the figure to the right.
For information about the location of the connectors on the Bitsy, refer to

3.6.2 J2: PCMCIA
Production option: Mating ejector Amp #146019-1
The 68-pin PCMCIA socket conforms to the PCMCIA standard for 3.3V and 5V Type II cards. It
will supply up to 500 mA of 5V current. The socket is normally de-energized; the operating
system is responsible for turning on the socket when a card is inserted and turning it off when the
card is removed.
Ejector hardware is available for applications that require regular insertion and removal of
PCMCIA cards.
