5.2 Dynamic C Functions
5.2.1 Digital I/O
The RCM3000 was designed to interface with other systems, and so there are no drivers
written specifically for the I/O. The general Dynamic C read and write functions allow
you to customize the parallel I/O to meet your specific needs. For example, use
WrPortI(PEDDR, &PEDDRShadow, 0x00);
to set all the Port E bits as inputs, or use
WrPortI(PEDDR, &PEDDRShadow, 0xFF);
to set all the Port E bits as outputs.
When using the auxiliary I/O bus on the Rabbit 3000 chip, add the line
#define PORTA_AUX_IO
// required to enable auxiliary I/O bus
to the beginning of any programs using the auxiliary I/O bus.
The sample programs in the Dynamic C SAMPLES/RCM3000 folder provide further
examples.
5.2.2 Serial Communication Drivers
Library files included with Dynamic C provide a full range of serial communications sup-
port. The RS232.LIB library provides a set of circular-buffer-based serial functions. The
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 fin-
ished, allowing other functions to be performed between calls. For more information, see
the Dynamic C Function Reference Manual and Technical Note TN213, Rabbit Serial
Port Software .
5.2.3 TCP/IP Drivers
The TCP/IP drivers are located in the LIB\TCPIP folder. Complete information on these
libraries and the TCP/IP functions is provided in the Dynamic C TCP/IP User ’s Manual .
