Applicati on of ARM I2C Bus Interface Module in Data Acquisition

Abstract : In the design of a new flow totalizing instrument with ARM S3C44B0X as the core processor, A /D converter chip ADS1110 has been extended by using I2C bus interface module provided by ARM itself thus the data acquisition system with high accuracy is composed. In accordance with the feature of high precise A/D conversion, the optmial periphery circuit is designed, and the process of the relative software design is given . By combining soft ware design and hardware circuit the modularization of designing data acquisition circuits is fulfilled, and the accuracy and reliability of the system are enhanced .
Keywords : ARM I2C bus Data acquisition Flowtotalizing instrument
