# Eeprom emulation 功能测试

## 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

## 板级设置

- 无需特殊设置

## 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

## 运行示例

当工程运行后，串口会打印以下信息：

```console
------------ 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
