摘要
本文提出了一种基于USB总线传输协议的数据采集系统的设计方法。该系统应用CH372USB控制器与SPCE061A单片机完成设备与主机的通信。文中介绍了数据采集系统的总体设计思想及层次结构,并介绍了固件程序,设备功能驱动程序和应用程序的设计方法。该系统应用CH372内置固件模式屏蔽了相关USB协议,并使用SPCE061A自带的模数转换器对数据进行转换控制,使得硬件电路十分简单,可以广泛的应用与对各种数据的采集。
This article proposes a method to design a data acquisition system which is based on USB bus. The system applies the CH372 and theSPCE061A to complete the communication between the PC and the device. The paper introduces the idea and hiberarchy of the system .And also recommends the design of firmware ,device driver and application program.The system applies the CH372＇s internal mode to shield the protocol of USB , and uses the A/D of the SPCE061A to diverse the data .So the whole circuit is very simple and can be applied to many data acquisition system.
