New in FOC SDK 5.x

Features (Improvements vs 4.x) Benefits

STM32Cube based

• Usage of HAL and LL• Easy integration with other STM32Cube based

libraries

• Seamless support across whole STM32 family

Bridge between MC_workbench and

CubeMX

• Initialization of peripherals using Cube MX• Simplification of the project development flow

• Faster migration

Simplified FW architecture

• No more fully object oriented code

• Two distribution versions – no NDA

• Transparent debugging

• Easy access and customization

• Code size gain (-15% in average)

FOC SDK 5.x distribution policy

• Two packages of the SDK v5.x are available

• X-CUBE-MCSDK

• Full source code except specific algorithms (MTPA, CORDIC, flux weakening, rev up..)

• Accessible from ST.com with my.ST registration
