MCS-96单片机A_D转换器应用-通过检测AD_RESULT（LO）中的S位来判定A/D转换是否完成。需要注意的是，当发出启动A/D转换命令后，AD_RESULT中的S位要经过8个状态周期后才能对其查询.-MCS-96 microcontroller A_D converter applications-through detection AD_RESULT (LO) the S to determine A/D converter whether completed. We need to be aware that when issued start A/D conversion orders, AD_RESULT the S-8 to go through cycle after the state of its inquiries.

The Windows Driver Model assumes that a hardware device can have several drivers, each of which contributes in some way to the successful management of the device. WDM accomplishes the layering of drivers by means of a stack of device objects. I discussed this concept in Chapter 2. Up until now, I’ve been talking exclusively about the function driver that manages the main functionality of a device. To round out this book, I’ll describe how you write a filter driver that resides above or below the function driver and modifies the behavior of the device in some way by filtering the I/O request packets (IRPs) that flow through it.
