5.2.3 Serial Communication Drivers
Library files included with Dynamic C provide a full range of serial communications sup-
port. The LIB\Rabbit3000\RS232.LIB library provides a set of circular-buffer-based
serial functions. The LIB\Rabbit3000\PACKET.LIB library provides packet-based
serial functions where packets can be delimited by the 9th bit, by transmission gaps, or
with user-defined special characters. Both libraries provide blocking functions, which do
not return until they are finished transmitting or receiving, and nonblocking functions,
which must be called repeatedly until they are finished, allowing other functions to be per-
formed between calls. For more information, see the Dynamic C Function Reference
Manual and Technical Note TN213, Rabbit Serial Port Software.
5.2.4 TCP/IP Drivers
The TCP/IP drivers are located in the LIB\Rabbit3000\TCPIP folder. Complete informa-
tion on these libraries and the TCP/IP functions is provided in the Dynamic C TCP/IP
User’s Manual.
5.2.5 NAND Flash Drivers
The Dynamic C LIB\Rabbit3000\NANDFlash\NFLASH.LIB library is used to interface
to NAND flash memory devices on the RCM3900. The function calls were written specif-
ically to work with industry-standard flash devices with a 528-byte page program and
16896-byte block erase size. The NAND flash function calls are designed to be closely
cross-compatible with the newer serial flash function calls found in the LIB\Rabbit3000\
SFLASH.LIB
library. These function calls use an nf_device structure as a handle for a
specific NAND flash device. This allows multiple NAND flash devices to be used by an
application.
More information on these function calls is available in the Dynamic C Function Refer-
ence Manual.
The NAND flash is ideally suited to store files with a directory structure. The Dynamic C
FAT file system module provides support for a file system for use in a Rabbit-based
system. The supporting documentation for the Dynamic C FAT File System and the sample
programs in the SAMPLES\FileSystem\FAT folder illustrate the use of the Dynamic C
FAT file system.
