| Abstract: | The characteristics of I2C bus and its peripheral devices are introduced. A measurementand control system for pressure which consists of the AT89C51 single-chip microcomputer as maincontroller, and the chip with interface of I2C bus as peripheral device are designed. The workingprinciple of the system, the function of the hardware are also discussed and the framework of thesoftware design is given. As a result, the precisely control for pressure in a large container is realized. |
