Signal sampling and storage system based on MSP430 MCU

For the purpose of recording the vector sound field information which can be used in the subsequent research of vector sound field feature,system platform for signals sampling and storage is constructed with the micropower MSP430 microcontroller as a core.Controlled by MSP430 microcontroller,analog signals are sampled by AD7655 high-speed multi-channel analogue to digital converter(ADC).Quantified data is inputted into the large capacity CF flash memory via IDE ports according to fixed timing by MSP430 microcontroller.For the compatibility with PC,data in CF card are organized in standard FAT32 cluster DAT files.The data can be accessed by PC conveniently.This system has been used in the underwater acoustic equipment.
