2.3 Design Standards
The same functionality can be accomplished in many ways using the Rabbit. By publish-
ing design standards, or standard ways to accomplish common objectives, software and
hardware support become easier.
2.3.1 Programming Port
Rabbit Semiconductor publishes a specification for a standard programming port (see
Appendix A.1, “The Rabbit Programming Port,”) and provides a converter cable that may
be used to connect a PC serial port to the standard programming interface. The interface is
implemented using a 10-pin connector with two rows of pins on 2 mm centers. The port is
connected to Rabbit serial port A, to the startup mode pins on the Rabbit, to the Rabbit
reset pin, and to a programmable output pin that is used to signal the PC that attention is
needed. With proper precautions in design and software, it is possible to use serial port A
as both a programming port and as a user-defined serial port, although this will not be nec-
essary in most cases.
Rabbit Semiconductor supports the use of the standard programming port and the standard
programming cable as a diagnostic and setup port to diagnosis problems or set up systems
in the field.
2.3.2 Standard BIOS
Rabbit Semiconductor provides a standard BIOS for the Rabbit. The BIOS is a software
program that manages startup and shutdown, and provides basic services for software run-
ning on the Rabbit.
2.4 Dynamic C Support for the Rabbit
Dynamic C is Rabbit Semiconductor’s interactive C language development system.
Dynamic C runs on a PC under Windows 95/98/Me/XP or Windows NT. It provides a
combined compiler, editor and debugger. The usual method for debugging a target system
based on the Rabbit is to implement the 10-pin programming connector that connects to
the PC serial port via a standard converter cable. Dynamic C libraries contain highly per-
fected software to control the Rabbit. These includes drivers, utility and math routines and
the debugging BIOS for Dynamic C.
In addition, the internationally-known real-time operating system, uC/OS-II, has been
ported to the Rabbit and is available starting with Dynamic C Premier v. 6.50.
