RabbitCore RCM2000

Getting Started 1
1. OVERVIEW
The RabbitCore RCM2000 series is an advanced line of mod-
ules that incorporates the powerful Rabbit 2000 microprocessor,
flash memory, and static RAM, all on a PCB not much larger
than the size of a business card.
The RCM2000 series modules are designed for use on a motherboard that supplies power
and interfaces with real-world I/O devices. Up to 40 pins of I/O and four serial ports are
available for system interfacing.
To accommodate a variety of user and production needs, the RCM2000 family includes
versions with varying amounts of onboard memory. All modules within the family are pin-
for-pin compatible and may be installed or swapped in a matter of minutes.
1.1 RCM2000 Series Description
There are three production models in the RCM2000 series. Their standard features are
summarized in Table 1.
The RCM2000 is the version that is included in the Development Kit.

1.3 Development Software
The RCM2000 series of modules uses the Dynamic C development environment for rapid
creation and debugging of runtime applications. Dynamic C provides a complete develop-
ment environment with integrated editor, compiler and source-level debugger. It interfaces
directly with the target system, eliminating the need for complex and unreliable in-circuit
emulators.
Dynamic C must be installed on a Windows workstation with at least one free serial
(COM) port for communication with the target system. See Chapter 3., “Installing
Dynamic C,” for complete information on installing Dynamic C.

1.4 How to Use This Manual
This Getting Started manual is intended to give users a quick but solid start with the
RCM2000 series modules. It does not contain detailed information on the module hard-
ware capabilities or the Dynamic C development environment. Most users will want more
detailed information on some or all of these topics in order to put the RCM2000 to effec-
tive use.
1.4.1 Additional Product Information
Detailed information about the RabbitCore RCM2100 series is provided in the Rabbit-
Core RCM2000 User’s Manual, which is available on the accompanying CD-ROM in
both HTML and Adobe PDF format.
Some advanced users may choose to skip the rest of this introductory manual and proceed
directly with the detailed hardware and software information in the User’s Manual.
TIP: We recommend that anyone not thoroughly familiar with Z-World controllers at
least read through the rest of this manual to gain the necessary familiarity to make use
of the more advanced information.
1.4.2 Additional Reference Information
In addition to the product-specific information contained in the RabbitCore RCM2000
User’s Manual, several higher level reference manuals are provided in HTML and PDF
form on the accompanying CD-ROM. Advanced users will find these references valuable
in developing systems based on the RCM2100 series modules:
•Dynamic C User’s Manual
•Rabbit 2000 Microprocessor User’s Manual

1.4.3 Using Online Documentation
We provide the bulk of our user and reference documentation in two electronic formats,
HTML and Adobe PDF. We do this for several reasons.
We believe that providing all users with our complete library of product and reference
manuals is a useful convenience. However, printed manuals are expensive to print, stock,
and ship. Rather than include and charge for manuals that every user may not want, or pro-
vide only product-specific manuals, we chose to provide our complete documentation and
reference library in electronic form with every Development Kit and with our Dynamic C
development environment.
Finding Online Documents
The online documentation is installed along with Dynamic C, and an icon for the docu-
mentation menu is placed on the workstation’s desktop. Double-click this icon to reach the
menu. If the icon is missing, create a new desktop icon that points to default.htm in the
docs folder, found in the Dynamic C installation folder.
The latest versions of all documents are always available for free, unregistered download
from our Web sites as well.
Printing Electronic Manuals
We recognize that many users prefer printed manuals for some uses. Users can easily print
all or parts of those manuals provided in electronic form. The following guidelines may be
helpful:
•Print from the Adobe PDF versions of the files, not the HTML versions.
NOTE: The most current version of Adobe Acrobat Reader can always be downloaded
from Adobe’s web site at http://www.adobe.com. We recommend that you use ver-
sion 4.0 or later.
•Print only the sections you will need to refer to often.
•Print manuals overnight, when appropriate, to keep from tying up shared resources dur-
ing the work day.
•If your printer supports duplex printing, print pages double-sided to save paper and
increase convenience.
NOTE: If you do not have a suitable printer or do not want to print the manual yourself,
most retail copy shops (e.g., Kinkos, AlphaGraphics, etc.) will print the manual from the
PDF file and bind it for a reasonable charge—about what we would have to charge for a
printed and bound manual.

2. HARDWARE SETUP
This chapter describes the RCM2000 hardware in more detail,
and explains how to set up the accompanying Prototyping
Board.
NOTE: This chapter (and this manual) assume that you have the RabbitCore RCM2000
Development Kit. If you purchased an RCM2000 series module by itself, you will have
to adapt the information in this chapter and elsewhere to your test and development
setup.
2.1 Development Kit Contents

2.2 Overview of the Prototyping Board
The Prototyping Board included in the Development Kit makes it easy to connect an
RCM2000 module to a power supply and a PC workstation for development. It also pro-
vides an array of basic I/O peripherals (switches and LEDs), as well as a prototyping area
for more advanced hardware development.
For the most basic level of evaluation and development, the Prototyping Board can be
used without modification.
As you progress to more sophisticated experimentation and hardware development, modi-
fications and additions can be made to the board without modifying or damaging the
RCM2000 itself.
The Prototyping Board is shown in Figure 2 below, with its main features identified.

2. Connect RCM2000 to PC
Connect the 10-pin connector of the programming cable labeled PROG to header J3 on the
RCM2000 module as shown in Figure 4 below. Be sure to orient the red edge of the cable
towards pin 1 of the connector. (Do not use the DIAG connector, which is used for a normal
serial connection.)
Figure 4. RCM2000 Power and Programming Connections
3. Power Supply Connections
Hook up the connector from the wall transformer to header J5 on the Prototyping Board as
shown above. The orientation of this connector is not important since the VIN (positive)
voltage is the middle pin, and GND is available on both ends of the three-pin header J5.
Plug in the wall transformer. The power LED on the Prototyping Board should light up.
The RCM2000 and the Prototyping Board are now ready to be used.
NOTE: A RESET button is provided on the Prototyping Board to allow a hardware reset.

2.4 Where Do I Go From Here?
We recommend that you proceed to the next chapter and install Dynamic C (if you do not
already have it installed), then run the first sample program to verify that the RCM2000
and the Prototyping Board are set up and functioning correctly.
If everything appears to be working, we recommend the following sequence of action:
1. Run all of the sample programs described in Chapter 4 to get a basic familiarity with
Dynamic C and the RCM2000’s capabilities.
2. For further development, refer to the RabbitCore RCM2000 User’s Manual for details
of the module’s hardware and software components.
A documentation icon should have been installed on your workstation’s desktop; click
on it to reach the documentation menu. You can create a new desktop icon that points to
default.htm in the docs folder in the Dynamic C installation folder.
3. For advanced development topics, refer to the Dynamic C User’s Manual, also in the
online documentation set.
2.4.1 Technical Support
NOTE: If you purchased your RCM2000 through a distributor or through a Z-World or
Rabbit Semiconductor partner, contact the distributor or partner first for technical support.
If there are any problems at this point:
•Check the Z-World/Rabbit Semiconductor Technical Bulletin Board at
www.zworld.com/support/bb/.
•Use the Technical Support e-mail form at www.zworld.com/support/support_submit.html.

3. INSTALLING DYNAMIC C
To develop and debug programs for the RCM2000 series (and
for all other Z-World and Rabbit Semiconductor hardware), you
must install and use Dynamic C. This chapter takes you through
the installation of Dynamic C, and then provides a tour of its
major features with respect to the RCM2000 series.
3.1 An Overview of Dynamic C
Dynamic C integrates the following development functions into one program:
•Editing
•Compiling
•Linking
•Loading
•Debugging
In fact, compiling, linking and loading are one function. Dynamic C does not use an In-
Circuit Emulator; programs being developed are downloaded to and executed from the
“target” system via an enhanced serial-port connection. Program development and debug-
ging take place seamlessly across this connection, greatly speeding system development.
Other features of Dynamic C include:
•Dynamic C has an easy-to-use built-in text editor. Programs can be executed and
debugged interactively at the source-code or machine-code level. Pull-down menus and
keyboard shortcuts for most commands make Dynamic C easy to use.
•Dynamic C also supports assembly language programming. It is not necessary to leave
C or the development system to write assembly language code. C and assembly lan-
guage may be mixed together.
•Debugging under Dynamic C includes the ability to use printf commands, watch
expressions, breakpoints and other advanced debugging features. Watch expressions
can be used to compute C expressions involving the target’s program variables or func-
tions. Watch expressions can be evaluated while stopped at a breakpoint or while the
target is running its program.

14 RabbitCore RCM2000
•Dynamic C provides extensions to the C language (such as shared and protected vari-
ables, costatements and cofunctions) that support real-world embedded system devel-
opment. Interrupt service routines may be written in C. Dynamic C supports
cooperative and preemptive multi-tasking.
•Dynamic C comes with many function libraries, all in source code. These libraries sup-
port real-time programming, machine level I/O, and provide standard string and math
functions.
•Dynamic C compiles directly to memory. Functions and libraries are compiled and
linked and downloaded on-the-fly. On a fast PC, Dynamic C can load 30,000 bytes of
code in 5 seconds at a baud rate of 115,200 bps.
3.2 System Requirements
To install and run Dynamic C, your system must be running one of the following operating
systems:
•Windows 95
•Windows 98
•Windows NT
•Windows Me
•Windows 2000
3.2.1 Hardware Requirements
The PC on which you install Dynamic C for development of RCM2000-based systems
should have the following hardware:
•A Pentium or later microprocessor
•32 MB of RAM
•At least 40 MB of free hard drive space
•At least one free COM (serial) port for communication with the target systems
•A CD-ROM drive (for software installation)

Getting Started 15
3.3 Installing Dynamic C
Insert the Dynamic C CD-ROM in the drive on your PC. If autorun is enabled, the CD
installation will begin automatically.
If autorun is disabled or the installation otherwise does not start, use the Windows
Start > Run menu or Windows Disk Explorer to launch SETUP.EXE from the root folder
of the CD-ROM.
The installation program will guide you through the installation process. Most steps of the
process are self-explanatory and not covered in this section. Selected steps that may be
confusing to some users are outlined below. (Some of the installation utility screens may
vary slightly from those shown.)
3.3.1 Program & Documentation File Location
Dynamic C’s application, library and documentation files can be installed in any conve-
nient location on your workstation’s hard drives.
The default location, as shown in the example above, is in a folder named for the version
of Dynamic C, placed in the root folder of the C: drive. If this location is not suitable, enter
a different root path before clicking Next >. Files are placed in the specified folder, so do
not set this location to a drive’s root directory.

16 RabbitCore RCM2000
3.3.2 Installation Type
Dynamic C has two components that can be installed together or separately. One compo-
nent is Dynamic C itself, with the development environment, support files and libraries.
The other component is the documentation library in HTML and PDF formats, which may
be left uninstalled to save hard drive space or installed elsewhere (on a separate or net-
work drive, for example).
The installation type is selected in the installation menu shown above. The options are:
•Typical Installation — Both Dynamic C and the documentation library will be installed
in the specified folder (default).
•Compact Installation — Only Dynamic C will be installed.
•Custom Installation — You will be allowed to choose which components are installed. This
choice is useful to install or reinstall just the documentation.
