用PIC单片机对EEPROM进行读写操作。

按单排按键“1”，程序从从8位拨动开关读入地址（范围0x00～0xFF），并从EEPROM读出该地址的值，地址与数据都显示在液晶屏上。

按单排按键“2”，程序从从8位拨动开关读入地址（保存，作为写入地址），液晶屏提示输入8位数据，此时拨动8位开关，再按一次按键“2”将拨动开关的状态（8位数据）写入之前保存的地址-PIC single-chip EEPROM with read and write operations on. By single-row button " 1" , the program from the DIP switch from the 8-bit read address (range of 0x00 ~ 0xFF), and EEPROM read out from the value of the address, address and data are displayed on the LCD screen. By single-row button " 2" , the program from the DIP switch from the 8-bit read address (saved as a write address), LCD screen prompted to enter 8-bit data, when the eight DIP switches, a button and then " 2 " The state of the DIP switch (8-bit data) into the address before the preservation of
