基于MSP430的便携式数据采集器及信号发生器

MSP430 based portable waveform acquisition and signal generator

为了实现便携式数据采集器和信号发生器,以及灵活的PC机控制、信号处理和显示结果的功能,采用MSP430F169作为主控芯片实现AD与DA转换,利用PDIUSBD12芯片大于10Mbps的传输率的优势,作为通信接口实现与PC机之间的数据传输,以实现信号波形产生和数据采集的收集。实验结果表明,利用低功耗的MSP430丰富的外围接口,不仅能够使用PC机的USB供电实现很好的波形的产生,而且能够将采集的信号波形通过PC机实现丰富的信号处理功能。

In order to achieve a portable data acquisition and signal generator with flexible PC control, signal processing and the function of display the results,this paper uses MSP430F169 as the master chip to make AD and DA conversion,PDIUSBD12 chip as a communication interface between PC data transfer with it＇ s more than 10Mbps data transfer rate, thus it can achieve waveforrn generation and data acquisition collection. The experimental results show that the use of low-power MSP430-rich peripheral interfaces, not only can use the PC＇ s USB powered to achieve good waveform generation, but also can send signal waveforms it gets to PC and achieves rich signal processing functions.
