2.4.1 Documentation
Several types of documentation are available on www.st.com. Table 3 provides a reminder
of the main technical documents with a short description of their contents.
Tip: The MCU Finder application can be useful for document access and
bookmarking in addition to its primary usage for identifying the
suitable STM32 product. The MCU Finder application is available for
use on PC, smartphone, and tablet. More information is available on
www.st.com.
Trick: When an Internet search engine is used to get access to STMicroelectronics
documents, it is advised to search with an explicit mention of STMicroelectonics
web site so that references to genuine documents are obtained. In the Google
