从PCI板卡接收中断，然后以DMA的方式将板卡数据传至PC。 2.主要优点：内建DMA缓存，实时性好，中断发生140ns左右后数据即可上传，速率可到100MB/s。代码中有详细注释。该驱动已在Windows XP平台下通过测试。-Receive interrupts from the PCI card, then the DMA mode of data transmitted to the board PC. 2 main advantages: built-in DMA buffer, re

基于PDIUSBD12的驱动源代码 完全可用 接收过程: usbserial模块会在该设备打开时就启动一个urb在那等待设备端发数据过来, 收到数据后就push到上层tty设备的缓冲中去-Fully available based on the PDIUSBD12 the driver source code Receiving process: usbserial module when the device is turned on to start a urb go after t
