在S3C2410A上实现MDB/ICP协议

Realization of MDB/ICP Based On S3C2410A

为了让ARM处理器芯片S3C2410A支持MDB/ICP协议,使功能强大的嵌入式处理器成为VMC设备来提升自动售货机的软件系统功能,采用逆推的思维方式,构造不同MDB总线数据,设置S3C2410A UART不同的接收模式。根据软件试验结果,利用S3C2410A芯片设计的bug,得到了一种让S3C2410A完美支持MDB协议的巧妙方法,具有较高的实际应用价值。

In order to make ARM chip S3C2410A support MDB/ICP, the more powerful embedded processor be used as a VMC equipment to promote the vending machine software system, backwards way of thinking is used. Experiments are carried out with different MDB data and different receive modes of S3C2410A UART. According to software test results, a perfect way to make S3C2410A support MDB/ICP is designed using S3C2410A bugs, showing high value in practical applications.
