例程使用串口调试，串口切换到P3.6和P3.7。
单片机工作频率22.1184MHz。波特率115200.

数据组织形式：
包头+校验和+数据
包头=FF 00 55 AA，校验和就是数据累加值，取低16位。

开机先弹出菜单：


接收←System on!
      1.Read||2.Write||3.Erase||4.Search pack||5.Restore pack
      6.Modify pack||7.Show EP_Data arry||8.Show ALL EEPROM DATA||?.Show menu



发送→8 先把当前EEPROM的数据显示一遍。
接收←刚刷机，EEPROM全空。

特别注意：
我发现  设置用户EEPROM大小不能小于2K，否则就出问题了。暂时不明原因。即便程序里面用512字节，但是设置的时候还是要设置2K以上，不知为什么。

如果要存入的数据凑巧和包头一样，这个还能正常处理吗？

自己优化一下，在数据包里面找到包头，后面校验包就肯定不通过，你再往回找一个包头，直到数据校验通过了就行了。

我有一个想法不知道是否可行。就是用每一个字节的最高位D7作为是否未使用的标志，剩余D0~D6共7位用来保存数据，只不过每个字节保存的数据不能超过127（0x7F），超过就要用两个或者多个字节来存储。存入之前数据要处理一下，读出也要处理。因为初始数据都是0xFF，最高位都是1，就是未使用的，保存过数据的字节最高位就变成0了，这样查找应该很方便。

这个要根据你的数据的特点来处理，只要自己处理好逻辑就行，需要考虑一个是占据的空间是否太大，二是搜索计算时间是否过长，三是如何判断数据有效

你这都是写定长数据，不定长我觉得还是得考虑上链表

要有较复杂需求就干脆上文件系统了，fat不香吗。
这种情况就是用最低的代价满足80-90%的需求。
