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 introduced,and some sample codes for STM32F407 MCU are given.This paper can be a reference for similar software development projects.
