| Abstract: | 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. |
