GD32F407ZGT6硬件引脚可以完全替代STM32F407ZGT6吗?
以前项目的板子用的STM32F407ZGT6,现在要求主控芯片必须国产化,想直接替换成GD32F407ZGT6,不改变原先的外围电路,请问大佬们有尝试过的嘛,可以的话那就太省事了,我先给大家鞠个躬吧!!![img]https://bbs.21ic.com/static/image/smiley/comcom/3.gif[/img][img]https://bbs.21ic.com/static/image/smiley/comcom/3.gif[/img][img]https://bbs.21ic.com/static/image/smiley/comcom/3.gif[/img]

请问 STM32F407ZGT6 内存大小的问题
型号:[color=#f00000][b]STM32F407ZGT6[/b][/color], Heap_Size EQU 0x00000700 可以编译通过,Heap_Size EQU 0x00000800 就出错了?
