Abstract
A multi-channel general data acquisition system based on AT89S52 is introduced.The system can be used in data acquisition,data store,communication and demonstration.All of there use serial interface components.So it can reduce the wiring density and enhance the system reliability.The system hardware structure and real-time clock SD2001E are introduced in detail,and the software flow is given.
A significance statement is not available in the OpenAlex record.
A contribution statement is not available in the OpenAlex record.
Method details are not available in the OpenAlex metadata.
Findings are not separately available in the OpenAlex metadata.
Limitations are not available in the OpenAlex metadata.
Application details are not available in the OpenAlex metadata.
