摘　　要：由于STM32F407的SRAM地址不连续,造成动态内存分配存在问题,不能利用全部的片内192 KB SRAM资源。因此,本文介绍了使用多块不连续内存空间实现堆的软件方法,以及在STM32F407单片机上的软件实例。该方法可作为类似的单片机软件开发项目的参考。Because the SRAM address of STM32f407 is discontinuous,there is a problem in dynamic memory allocation,and all on-chip 192 KB SRAM resources cannot be used.Therefore the software method on implementing heap in non-continuous memory space is intro-duced,and some sample codes for STM32F407 MCU are given.This paper can be a reference for similar software development projects.
