5.2 Dynamic C Function Calls
5.2.1 Digital I/O
The RCM4300 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
to set all the Port E bits as inputs, or use
to set all the Port E bits as outputs.
When using the auxiliary I/O bus on the Rabbit 4000 chip, add the line
to the beginning of any programs using the auxiliary I/O bus.
The sample programs in the Dynamic C
examples.
5.2.2 Serial Communication Drivers
Library files included with Dynamic C provide a full range of serial communications sup-
port. The
PACKET.LIB
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 Rabbit Semiconductor’s Technical Note
TN213, Rabbit Serial Port Software.
