| 摘 要： | 以往的并口数据采集都是基于EPP模式,提出一种ECP模式下并口数据采集系统的实现方法,利用WinDriver生成Windows XP操作系统下的中断驱动程序,通过控制扩展控制寄存器(ECR)来实现Centronics协议下字节方式的并口数据采集功能.经对消防主机并口实时打印信息的采集证明系统可靠,此方法比EPP模式下实现简便.

| Abstract: | The parallel port's data acquisition always adopt EPP mode.A new method with parallel port's ECP mode was designed.The interruption service was produced by the WinDriver.By set the ECP's Extended Control Register(ECR),the byte mode parallel port can acquire 8bit data with the Centronics's protocol.The method was verified by acquiring the fire alarm system's print information.It is robust and simple. |
