Design of USB interface for data recorder based on ARM
|
Abstract:
A kind of design and application for a 128MB memory data recorder based on LPC2214 of Philips was introduced,which could record the exchange data between the industrial control equipments and help the engineers to analyze the working state of the industrial control system.Practical application indicates the feasibility of this design scheme.Compared with the traditional data recorder,its 128MB memory make the recording time through RS-422 increase greatly.Instead of serial port,using USB interface can decrease the transmission time evidently.
