用CodeVision AVR编写的简单源代码，演示如何使用DS1307和Shamsi/Miladi数据，并在Proteus中进行模拟。

在数字电路的设计中，时序设计是一个系统性能的主要标志，在高层次设计方法中，对时序控制的抽象度也相应提高，因此在设计中较难把握，但在理解RTL电路时序模型的基础上，采用合理的设计方法在设计复杂数字系统是行之有效的，通过许多设计实例证明采用这种方式可以使电路的后仿真通过率大大提高，并且系统的工作频率可以达到一个较高水平-In digital circuit design, timing design is a main indicator of system performance in high-level design methods, control of timing was also a corresponding increase in the abstract, so more difficult to grasp in the design, but in understanding the RTL circuit timing model based on rational design methods used in the design of complex digital systems is a well-established through many design examples prove that this approach can make the circuit after the simulation significantly improve pass rates, and the system operating frequency can reach a high level

此代码将有助于开发基于lan91c111的以太网连接。此项目将包括tripele spped ether net，并用于快速从局域网传输数据

此代码在SDT2.51下调试通过，可以在我的板子ARM DEVELOP BOARD V1.0上面跑！经测试也适应于恒丰公司S344BOX等采公板设计的开发板。在其上电以后LED会闪烁一下，接着串口0会输出一些系统信息 可以通过串口终端与系统交互，可以测试320X240 STN LCD,包括图形显示函数，ascii字符显示函数。-this code under the SDT2.51 debugging through, I can blame the ARM DEVELOP BOARD V1.0 above Run! After tests also adapted to Prudential and other mining companies S344BOX public board design development board. In his last-- after about LED blinks, Serial 0 then the output will be some system information through serial terminal and system interaction, can test the 320 X240 STN LCD, including graphic display function, ascii character display function.

DS1302是一种高性能，低功耗带RAM的实时时钟芯片，具有闰年功能，最大有效年份可达2100年，运行本例程序时，当前时间会在LCD1602上显示
