Step 3: Creating a New STM32CubeMX Project

Workflow steps:

1. Click the "New Project" link. A "New Project" dialogue box will appear.

2. Select an MCU part number. The dialogue will automatically grey out the peripherals that are not available for the selected part.

   In writing this example an STM32F439 part was selected in a BGA package.

3. For each peripheral of interest, either check the box or enter the number of peripherals of that type to be used. It is not possible to check the boxes of peripherals that do not exist on the selected MCU part, or enter a number that exceeds the number of a peripheral actually available on the selected MCU part.

4. Once both the MCU part number and the peripherals of interest have been selected, click "Ok" to close the new project dialogue and see the main design window.
