篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了EasyFlash 的使用感受相关的知识，希望对你有一定的参考价值。
我的硬件是W25Q32 + STM32F401CE
配置如下:
/* The minimum size of flash erasure. May be a flash sector size. */
#define EF_ERASE_MIN_SIZE 4096 /* @note you must define it for a value */
/* the flash write granularity, unit: bit
* only support 1(nor flash)/ 8(stm32f4)/ 32(stm32f1) */
#define EF_WRITE_GRAN 1 /* @note you must define it for a value */
/* backup area start address */
#define EF_START_ADDR (0) /* @note you must define it for a value */
/* ENV area size. It's at least one empty sector for GC. So it's definition must more then or equal 2 flash sector size. */
//ENV 区域大小。 GC 至少有一个空扇区。 所以它的定义必须大于或等于 2 个闪存扇区大小。
#define ENV_AREA_SIZE (5 * EF_ERASE_MIN_SIZE) /* @note you must define it for a value if you used ENV */
/* saved log area size */
#define LOG_AREA_SIZE (25 * EF_ERASE_MIN_SIZE) /* @note you must define it for a value if you used log */
/* print debug information of flash */
//#define PRINT_DEBUG
#define EF_ENV_USING_WL_MODE //启用擦写平衡功能
#define EF_ENV_USING_PFS_MODE //启用掉电恢复功能
#define EF_ENV_AUTO_UPDATE //启用自动增量功能首次开机的时候的日志
ENV start address is 0x00000000, size is 20480 bytes.

EasyFlash V4.1.99 is initialize success.
You can get the latest version on https://github.com/armink/EasyFlash .我的测试结构体是:
typedef struct {
char a;
short b;
int c;
float d;
double e;
} test_data_t;

ef_port_read() addr=0x0001, sector=0, size=1...有没有发现 sector0扇区读了很多次，我们是否可以这样优化代码：当连续读同一个扇区时候，就可以将该扇区整个读出来，放到cache中呢？
下面我们来试试开启cache后的开机：
