这个heap，只有在FATFS使用长文件名，并且这个配置为3的时候采才使用
[C] 纯文本查看 复制代码 #define _USE_LFN 0
#define _MAX_LFN 255
/* The _USE_LFN option switches the LFN feature.
/
/ 0: Disable LFN feature. _MAX_LFN has no effect.
/ 1: Enable LFN with static working buffer on the BSS. Always NOT thread-safe.
/ 2: Enable LFN with dynamic working buffer on the STACK.
/ 3: Enable LFN with dynamic working buffer on the HEAP.
/
/ When enable the LFN feature, Unicode handling functions (option/unicode.c) must
/ be added to the project. The LFN working buffer occupies (_MAX_LFN + 1) * 2 bytes.
/ When use stack for the working buffer, take care on stack overflow. When use heap
/ memory for the working buffer, memory management functions, ff_memalloc() and
/ ff_memfree(), must be added to the project. */ |
