ARM微控制器产品平台的换型及软硬件功能移植

Platform Changing of ARM Microcontroller and Function Transplantation of Hardware and Software

由于产品性能提升及产品中应用的原始ARM微控制器停产等多种因素,微控制器芯片通常需要升级或者换型。本文介绍了微控制器平台换型时需要考虑的要素及选型方案,并描述了AT91SAM7X256微控制器向STM32F407微控制器平台切换时的软硬件差异及实现过程。经实际产品验证,换型后的微控制器提高了数据通信频率及运算性能,降低了产品开发时间,并能够有效支持后续产品的迭代。

Due to a variety of factors such as product performance enhancement and the production of ARM microcontrollers used in products have been stopped,the microcontroller chips usually need to be upgraded or changed. In the article,the elements and selection schemes are introduced that need to be considered when changing the ARM microcontroller platform,and the hardware and software differences and the implementation process when the AT91 SAM7 X256 microcontroller is switched to the STM32 F407 microcontroller platform are described. Through the actual product verification,the changed microcontroller enhances the data communication frequency and computing performance,reduces product development time,and can effectively support the iteration of subsequent products.
