EEPROM读写程序: 先向EEPROM写入一幅图片数据

/****************************************************************
       实验名称：EEPROM读写演示程序
	       
		   晶振：内部   8M
	   接线方法：
	        1.PC0,PC1分别接EEPROM的SCL，SDA
			2.PA0-PA4分别接128*64显示屏的CS,SID,CLK,PSB,背光.
	  使用说明：
	        先向EEPROM写入一幅图片数据，然后从EEPROM中读取，并
			在128*64显示屏显示出来。
