2.1 S32DS brief introduction

S32 Design Studio for ARM The development environment is mainly for the convenience of user development S32K1xx The birth of the , It also supports KEA series , But the supporting graphic tools Processor Expert Currently only supported S32K1xx series .

S32 Design Studio for ARM At present, there are four versions ,V1.3,V2.0,V2.2,V2018.R1. among V2018.R1 The version has the most patches , Supported by SDK There are also the most versions ,NXP Most of the official website S32K1xx Routines are also based on this version of the development environment . But for just touching S32K1 Little buddy , I still recommend V2.2 edition , Here's why ：

• V2.2 Version of the development environment integrates RTM 3.0.0 Version of SDK,2018.R1 The version needs to be patched （ time-consuming ） To use this SDK.
• V2.2 Version can be SDK Update to RTM3.0.3 edition , Repair the RTM3.0.0 Some of the versions bug.
• although S32 Design Studio for S32 Platform 3.x The platform is updated S32K1xx Of RTM 4.0.0 edition , But the graphical configuration tool is changed to Config Tools, There is no relevant introduction Processor Expert many , Novices are not recommended to use .
