Rabbit Dynamic C Code Examples (Freeware)
| 3des.zip | Phil Karn's DES and 3DES routines ported to Dynamic C for the Rabbit. A demo program processes the NIST DES test vectors and times them. Here is the program output. |
|
A simple program demonstrating using uC/OS-II and TCP/IP together. It creates a target that can be pinged. |
|
|
UDP send and receive example program. |
|
|
This timer library uses 32 bit timestamps to create down timers and up timers. An arbitrary number of timers can be easily maintained. A demo program demonstrates using the timers. Version 1.13. |
|
|
The MEMINFO library
contains a routine that prints the Rabbit memory
configuration. The logical and physical addresses of the
memory segments and the memory quadrant settings are
displayed. |
Rabbit 2000 Memory Map
The Rabbit 2000 processor has an elaborate memory organization that allows a microcontroller core with a 64k address space to access 1 Meg of memory. The memory interfaces and particulars of the Dynamic C compiler also shape the memory map of a Rabbit system.
It is useful to have a memory map for the Rabbit to understand the chip operation and to find unused sections of memory to store data. A memory map also helps plan the tricky task of running code in RAM during flash reprogramming.
This document describes the memory map of a RCM2100 module with the default memory organization of a Dynamic C 7.21 program.
Rabbit 2000
Memory Map (Version 1.02, 11 Mar 2003)
This document will be improved as new information is discovered. Some items presently missing is the location and format of the user blocks and system ID blocks in flash memory and information on some interrupt vectors. If you have any information or suggestions to enhance this document, please send them to info@cardlabs.com
