The embedded data acquisition storage systems based on S3C2410

A data acquisition system with core of S3c2410, embedded a Linux operating system, can be used in the near-infrared spectrumeter to acquisite spectral data. The system included interfaces of A/D data acquisition interface which based on AD7715, the USB storage module, the module of keyboard for inputting the time of sampling and the other external interfaces. Function of system was assembled by system initialization, the adjustment of interval data collection, sample collection, data storage and so on. Experimental results showed that the sampling time could be changed by keyboard, the collection data also could be stored in U-disk, and the systematic errors were less than 0.2%.
