LCD12864显示实时时钟例程可运行

DS1302是美国DALLAS公司推出的一种高性能、低功耗的实时时钟芯片，附加31字节静态RAM，采用SPI三线接口与CPU进行同步通信，并可采用突发方式一次传送多个字节的时钟信号和RAM数据。

实时时钟可提供秒、分、时、日、星期、月和年，一个月小与31天时可以自动调整，且具有闰年补偿功能。

可以显示8×4行16×16点阵的汉字. 也可完成图形显示.低电压低功耗是其又一显著特点。

由该模块构成的液晶显示方案与同类型的图形点阵液晶显示模块相比，不论硬件电路结构或显示程序都要简洁得多，且该模块的价格也略低于相同点阵的图形液晶模块。

基本特性:l 低电源电压（VDD:++）l 显示分辨率:128×64点l 内置汉字字库，提供8192个16×16点阵汉字(简繁体可选)l 内置 128个16×8点阵字符l 2MHZ时钟频率、半透、正显STN显示方式： ll 驱动方式：1/32DUTY，1/5BIASl 视角方向：6点l 背光方式：侧部高亮白色LED，功耗仅为普通LED的1/5—1/10l 通讯方式：串行、并口可选l 内置DC-DC转换电路，无需外加负压l 无需片选信号，简化软件设计l 工作温度: 0℃ - +55℃ ,存储温度: -20℃ - +60℃模块接口说明*注释1：如在实际应用中仅使用串口通讯模式，可将PSB接固定低电平，也可以将模块上的J8和“GND”用焊锡短接。
