Applicantion of standard peripherals library for STM32F10X microcontrollers

In order to predigest the Embedded Software's development process of microcontrollers base on Cortex-M,and enhance the software portability,this paper introduce the file structures,interrelation,function of CMSIS and standard peripherals library V3.5.The development process was introduced by STM32F103VET6 microcontrollers base on Cortex-M3,using IAR FOR ARM6.30.This paper explained how to configure port and interruption by a example,shorten development time,and improve code efficiency.
