(DSP is the core of the Digital revolution, no matter
in the application of breadth or depth is still at an
unprecedented rate of forward development.
Digital signal processing is to use computer or
special treatment equipment, in digital form on
signal is analyzed, collection, synthesis, transform,
filtering and estimation, compression, identification
processing, in order to extract useful information
and effective transmission and applications.
This paper provides UART for a solution to
communication between DSP and PC. The serial communication
between DSP and personal computer can be realized by using UART CMOS chip of Texas
Instruments Inc., which can avoid writing the complicated software routine for the McBSP
of DSP, and has the advantages of simple programming high transmission capability, good
reliability and real time capability. In this paper, we introduce briefly a kind of UART
COMS chip TL16C550 and provide the hardware circuit
between TL16C550 and TMS320VC5402 and the way
how to program it.
