讨论：视频驱动开发（7146）与一般的PCI驱动开发有何不同？

通常你用另一个显示器,连接到你的目标板上(若你的目标板是AGP,则你的主机用PCI,etc),你先将它当作一个普通的PCI来做,做完了再写那个GDI驱动程序了.

我看不懂！;--(
我现在有一块7146+7113的PCI video capture，
能送一份纯粹的（无其他封装）ddk2k（wdm）的通用的pci驱动程序源码
以及测试的应用程序，（如获得7146配置信息，对gpio端口读写等等）
THANK YOU PREVIOUSLY！

pci桥用的是什么？
你这样的程序和一般的pci驱动驱动没什么区别

saa7146本身就有pci桥

我发给你了，接收吧，给分吧：）

请问如何写*.inf 文件以安装你的通用pci driver？

然后吧所有pci42.sys改成你编译后的文件名

这要分成两部分来做,你先做第一部分了.
然后再做第二个部分,我不明白你的应用,因此没办法给更多的解释.

能给我发一封吗？谢谢！！！

看这个INF，自己尝试着修改
