7. Projects

A Precision32 project contains files, build options, and project settings. Projects generally exist as a directory

containing sub-directories and files. The project structure seen in the IDE is replicated physically on the disk.

However, a project may also contain linked files or directories which are just pointers to files or folders outside of

the project directory.

7.1. Project Structure

The projects generated by the Silicon Labs AppBuilder and the SDK follow a recommended project structure.

These projects have three categories of source files:

1. The my* files and any user generated files are located in a src subdirectory under the project directory.

AppBuilder will generate my* files if they do not exist, but will not modify existing copies. This ensures that

user updates to my* files are safe when re-exporting a project from AppBuilder.

2. Generated (g*) files are located in src\generated. These files contain all the automatically generated

AppBuilder code. These files will always be overwritten when a project is re-exported, and any user

changes to these files will be lost.

3. The si32 SDK firmware package consisting of the HAL, code examples, and si32Library is located in a

linked folder at C:\SiLabs\32bit\si32-x.y by default, where x is the major version and y is the minor

version.

Each project is compiled against a version of the HAL or si32Library.

7.1.1. Setting the Silicon Labs SDK Path

The Silicon Labs HAL revision is selected using the drop-down menu in the Precision32 IDE footer shown in

Figure 3.

Figure 3. Selecting the Silicon Labs SDK Path

A warning is displayed if the IDE cannot find the previously-selected path.

For projects that do not use the Silicon Labs SDK, this drop-down menu can be toggled on or off by clicking on
