移植汉字显示程序，提示内存空间不够？

袁超

程序编译之后出现多条关于内存空间不够的报错，主芯片是STM32F103C8T6，MDK->Target里的默认设置IROM1 size: 0x10000, IRAM1 size: 0x5000
把IROM1/IRAM1 size分别改成0x40000/0x10000（显然与实际不符）后编译通过，请问不做这项改动的情况下有什么办法通过编译吗？

malloc.h这个文件里面的东西，你可以修改的

内存不够就是无法编译通过

实际芯片硬件资源就没有那么多，那改动编译够不能运行也没什么用，想办法优化代码，要么就换芯片

字库很大的，不要把字库链接到工程里面，动不动就好几M，上10M的。可以把字库下载到外部可寻址的FLASH中。

目前将MEM_MAX_SIZE设到10k可以用了，谢谢！就是不知道后面工程变大会不会还是不够
