Development of Communication & Storage System for NIR Spectrometer Based on ARM-Linux

Based on SD memory card, the communication & storage system of the embedded portable spectrometer was designed, so the spectrometer can save data and change the analysis model files. In the system, SD card was used to store data files, and the communication function was designed by using serial port to send the file and command and receive the file. So the system can be used to accomplish uploading data files and downloading the analysis model file. Experiments show that the hardware, the ARM-layer program and the PC-layer program of the system can realize the functions of communication and storage.
