; /*******************************************************************************
; 标题： EEPROM读写试验(按钮输入) *
; ********************************************************************************
; *
; 此例程学员更进一步地熟悉并掌握（存储芯片AT2402）的操作，有保存和读取操作 *
; 了解掌握I2C总线接口的工作原理及一般编程方法。 *
; *
; 跳线操作：P0（JP10）连 数码管（JP12） *
; P1（JP8 ）连 独立按键（JP5） *
; *
; 具体操作： 第1个按钮保存 第2个按钮读取 *
; 第3个按钮减减 第4个按钮加数 *
; *
; 希望学员认真体会消化此例程！ *
