摘　　要：本文结合一实例介绍了微机大容量多功能I/O接口的设计和调试。其中包括微机外中断系统的硬件结构和软件配置,I/O接口系统结构设计,模拟量,数字量的输入输出等。该接口具有功能较强,容量大,成本低,适合国情等特点。A microcomputer interface with a large number of channels and multifunctions is reported here by explaining how to design and adjust it with a practical example. The hardware architecture and software construction of it's external interrupt systems are also included. Some other topics as system architecture design of I/O interface, the input and output of analog and digital parameters are also introduced. It has been confirmed that the I/O interface reported has many advanced characteristics as multi-function, a number of channels, lower in cost and suitable for chinese environments after more than one year practical operation in factory.
