Host Software
4-23 Functional Overview
4.4 Host Software
The DSK software includes several source-code files that manipulate the par-
allel printer port and perform the necessary functions to initialize and commu-
nicate with the ’C31. The commands in each of the source-code files are sum-
marized in the following subsections. The source files that are typically linked
include:
driver.cpp includes driver-level routines that control the host’s
parallel printer port interface.
target.cpp includes the low-level routines that manipulate the data
transmissions into packets that are recognized by the
’C31 communications kernel.
object.cpp uses the target- and driver-level routines to initialize
and download programs to the ’C31.
dsk_coff.cpp includes DSK and COFF file loader and utilities.
errormsg.cpp includes text strings associated with function returns.
symbols.cpp includes symbol table support routines.
helpmsg.cpp includes command-line help message.
The following subsections describe the routines contained in each of these
files.
DSK software also includes an assembler and a debugger. These are de-
scribed in Chapter 5,
Using the DSK Assembler, and Chapter 7, Using the DSK
Debugger.
