Why migrate from HAL to StdPeriph_Lib?

The scope of these defines is:

•

Interrupt IRQ channel definition inside the stm32w108xx.h file

•

Vector table, one startup file per product

•

Peripheral memory mapping and physical register address definition

•

Product configuration: external quartz (HSE) value, etc.

•

System configuration functions

•

Features with different/incompatible implementations across the family

These defines do not apply to peripheral drivers. These drivers always support the

features of the family superset.
