如何在驱动程序函数XXX_Open中获取端口号？

问题描述

您好，

（Win CE 6.0 R3，VS 2005，Digi CC9M2443）

我写了一个驱动程序来创建一个PWM在一个portpin，工作正常。现在有更多的端口可以输出PWM并且我想用相同的驱动器控制它们并且具有固定的分配硬件PWM通道0< - >。 PWM1：，PWM通道1 - > PWM2：
等等。

要做到这一点，我想我需要知道驱动程序函数PWM_Open传递给CreateFile的端口名。 但是没有参数（??）

如何做？

感谢您的帮助

Hello,

(Win CE 6.0 R3, VS 2005, Digi CC9M2443)

I wrote a driver to create a PWM at a portpin, works fine. Now there are more portpins that can output a PWM and I want to control them with the same driver and have a fixed assignment hardware PWM channel 0 <-> PWM1:, PWM channel 1 <-> PWM2: and so on.

To do this I think I need to know in drivers function PWM_Open the portname that was passed to CreateFile.  But there is no parameter for this (??)

How to do it?

Thank you for any help

Martin
