摘要
数据的采集与处理广泛的应用在自动化领域中,由于应用的场合不同,对数据采集与处理所要求的精度也不相同。考虑到测量精度要求,详细的阐述了以MSP430F149为主控芯片的系统软硬件的研究、设计和实现,介绍了如何采用压控振荡器LM331与控制器MSP430F149内部Timer模块构成ADC,即线性放电法(威尔金逊法)ADC。
Collection of data and processing apply in the automatic field, yet with the diverse occasional so is the precision varies. Given that request of detecting precision, the detailed description rest on the research ,designing and realization based on systematic software＇s research, designing and realization centered on MSP430F149 and introduced how to adopt pressuring oscillator LM331 and controller MSP430F149 Timer to construct ADC, i. e. , liner discharging（Wilkinson ） ADC.
