Chapter 8: Developing Your Application
4. Remove
the
DSPpro Utility Disk
from the floppy drive of the host PC and insert the
DSPpro
Boot Disk
. Make sure it has your application program copied onto it.
5. Reset the controller using the reset button or by toggling power to the controller. The
DSPpro will then attempt to connect to the REMSVR application running on the host
computer.
6. Upon successful connection, the DSPpro controller will attach to the REMSVR program
running on the host computer and download DOS from the
DSPpro Boot Disk
in the host
computer’s floppy drive. The output on the screen of the host should look similar to the
following:

4. When you see the A:\> prompt, you are ready to execute your program. Enter its name at the
prompt and press <RETURN>.
5. Your program should execute on the DSPpro, and you will see the console output (if any) on
the monitor of your host computer.
6. To exit REMSVR, type Alt-X. Your program will continue to run on the DSPpro
uninterrupted until it terminates.
8.2.4 Configure DOS startup files
The
DSPpro Boot Disk
can contain standard DOS configuration files to provide additional
functionality to your application. These files,
AUTOEXEC.BAT
and
CONFIG.SYS
, can be
used to set system variables, and to control the loading of your application. For example, you
could have the DSPpro automatically execute your application (or series of applications) upon
boot.
Because the DSPpro runs MS-DOS 6.22, you must be sure to follow the appropriate syntax for
your AUTOEXEC.BAT and CONFIG.SYS files. This syntax is described in detail in the
Microsoft publication
Microsoft MS-DOS Concise User’s Guide
. To order a copy of this
publication, contact the Microsoft Sales Information Center at (800) 426-9400.
8.3 Committing your application to flash memory
Once you have completed developing and debugging your application, you are ready to copy the
contents of the boot disk to flash memory on the DSPpro. After loading the program to flash
memory, the DSPpro controller can execute it completely independent of the host.
