Application note
Migration and compatibility guidelines
for STM32W108xx microcontroller applications based on the HAL
Introduction
The purpose of this application note is to explain how to migrate an application based on the
STM32W108xx firmware library (HAL) to a standard STM32W108xx firmware standard
library FWLib.
To that aim, this document provides detailed information about the two libraries and
highlights the differences between them.
To benefit fully from the information in this application note, the user should be familiar with
the STM32W108xx microcontroller products. The STM32W108xx datasheets and the
STM32Wxxx Flash memory microcontrollers programming manual (PM0073) are available
from www.st.com.
However, detailed guidelines regarding the migration of bit and register naming used in the
HAL and in the StdPeriph_Lib are documented in a separate document. Please refer to
AN4142: STM32W108xx datasheet bit and register naming migration.
This application note applies to the products listed in Table 1.
