AN670 G ETTING S TARTED WITH THE S ILICON L ABS PRECISION32™ A PP BUILDER 1. Introduction Precision32™ AppBuilder is a software program that generates configuration code for MCU devices. The software dynamically generates configuration code for peripherals, clocks, and pins in user-definable modes, greatly simplifying the device initialization process. This application note overviews the AppBuilder software for the Silicon Labs 32-bit microcontrollers. Figure 1. Precision32 AppBuilder 2.

Creating a New Project 1. Start a new project by selecting New Project… from the File menu, or click the New Project… link on the Start Page. This will display a New Project window. Figure 2. Creating a New Project 2. In the New Project window, select the Family, Device, Revision, and SDK version. Each selection will reveal all other possible selections. a. The Revision selection is the MCU device revision. b. The SDK version determines the functions used by AppBuilder. This selection should match the SDK base path. 3. Name the project and select the location where the generated source will be exported. 4. Select the toolset (IDE) and compiler. 5. Select the Si
