这是一个读取ID卡的源代码，仅依靠8052的时钟读取125K频率的ID卡。-This is an ID card read the source code, only 8,052 on the clock read 125K frequency ID cards.

时钟芯片ds1302 程序 源程序按版本号放在文件夹中。里面有在Protues中仿真的DSN文件。 打开MPLAB的MCP文件进行编译 将DSN文件载入Protues中 将生成的HEX导入到Protues中的16F84A中　-> RUN-Clock chip DS1302 procedures in accordance with the version number on the source folder. Protues there are in the DSN file in the simulation. Open the MPLAB compiler of the MCP file DSN file loading will be generated by HEX will Protues into Protues in 16F84A in-

This version of the code is compatible only with the AT89C2051 due to the location of the data buffer and stack in RAM. The code may be modified to work with the AT89C1051 by relocating or resizing the buffer and stack to fit into the smaller amount of RAM available in the AT89C1051.
