摘要
为了快速开发性价比高的基于USB接口的虚拟数据采集仪,采用了NI-VISA和CH372芯片的方案搭建一个通用的模板,并以一个温度信号的虚拟数据采集仪器的实例加以说明。实验表明该模板降低了USB通信的复杂度,缩短了开发周期。
In order to develop cost-effective and virtual data collection based on USB interface,this paper uses NI-VISA and CH372 chips to build a generic template and gives an example of virtual temperature acquisition instrument to explain how to use this template.Ex-periments show that using the template can reduce the complexity of USB communication and short the development cycle.
