8.1. Eeprom emulation 功能测试
8.1.1. 概述
EEPROM BASE示例对模拟eeprom的write、read、flush接口进行测试，主要包括以下测试内容：
写入
写入4笔数据
查看返回值是否正确
读取
读出写入的4笔数据
查看返回值是否正确
与写入数据进行比较
数据更新
更新前两笔的数据
查看更新情况
数据整理
整理所设置区域的数据，保留最新数据
8.1.2. 板级设置
无需特殊设置
8.1.3. 说明
一次写入的数据不要超过一个erase_size
需在user_config.h文件中设定EEPROM_MAX_VAR_CNT限制写入数据笔数的最大数量，默认为100笔
8.1.4. 运行示例
当工程运行后，串口会打印以下信息：
------------ flash->eeprom init ok -----------
start address: 0x80080000
sector count: 128
flash earse granularity: 4096
version: 0x4553
end address: 0x80100000
data write addr = 0x80080000, info write addr = 0x800fffe0, remain flash size = 0x7ffe0
valid count percent info count( 0 / 0 )

eeprom emulation demo
----------------------------------------
1 - Test eeprom write
2 - Test eeprom read
3 - Test eeprom update data
4 - Test eeprom flush whole area
5 - show area base info
Others - Show index menu
