Peripheral migration
As shown in Table 2 on page 9, there are three categories of peripherals. The common
peripherals are supported with the dedicated firmware library without any modification,
except if the peripheral instance is no longer present, you can change the instance and of
course all the related features (clock configuration, pin configuration, interrupt/DMA
request).
The modified peripherals such as: FLASH, ADC, RCC, DMA, GPIO and RTC are different
from the F1 series ones and should be updated to take advantage of the enhancements and
the new features in F2 series.
All these modified peripherals in the F2 series are enhancements in performance and
features designed to meet new market requirements and to fix some limitations present in
the F1 series.
3.1
STM32 product cross-compatibility
The STM32 series embeds a set of peripherals which can be classed in three categories:
The first category is for the peripherals which are by definition common to all products.
Those peripherals are identical, so they have the same structure, registers and control
bits. There is no need to perform any firmware change to keep the same functionality at
the application level after migration. All the features and behavior remain the same.
The second category is for the peripherals which are shared by all products but have
only minor differences (in general to support new features), so migration from one
product to another is very easy and does not need any significant new development
effort.
The third category is for peripherals which have been considerably changed from one
product to another (new architecture, new features...). For this category of peripherals,
migration will require new development at application level.
Table 2 below gives a general overview of this classification:
