Load and Edit Code: C/C++ Perspective
3.3.2
The codec code include file directives need to be modified to be used with Symphony Studio. First, right
click on each of the three include files (ada_equ.asm, ada_init.asm and ioequ.asm) in the Navigator View
and choose Rename. Change the extension of each of these three files from
contains two
Next, double click on the direct.asm file to open it in the editing window. At the top of the direct.asm file,
change the code from
The file extensions for the
directory is required because the Managed Make ASM scripts build the application in the Debug directory
(which is created if it does not already exist) within the project directory. The source files are located in
the project directory. In addition, the codec code does not use interrupts; therefore, the
vectors.asm
Finally, scroll down to the bottom of the direct.asm file and make the same changes for the

Example
Make sure you save any files that you modify. You can save files using the File > Save pull down menu
or by clicking on the Save button in the tool bar (which looks like a little diskette).

Now, you can build the project. Symphony Studio has two build choices, which depend on how the Build
Automatically option is set under the Project pull down menu. If this option is selected (check next to the
option), Symphony Studio builds the project every time a file within the project is modified and saved. If
this option is not selected (no check next to the option), Symphony Studio builds the project only when
instructed. If Build Automatically is not selected, you can direct Symphony Studio to build your project
by using the Project > Build All pull down menu, by clicking on the Build All button in the tool bar
(which looks like a little piece of paper with 1s and 0s on it) or, by right clicking on the project name in
the Navigator View and choosing Build Project. If the code was modified correctly, a few warnings may
appear in the Console window at the bottom of the Symphony Studio, but no errors.
