Class #422: Writing Windows CE Device Drivers, Principle to Practice

摘要

Device driver writers possess a special blend of software and hardware skills (among other things). They need to write highly structured and elegant code as well as debug down to the register level of the hardware. They have to do their tasks with less then optimal debug hardware. They often make do without JTAG or Ethernet debug tools and fix tough problems with just their wit and a GPIO line. If you have the tenacity to write device drivers read on. Writing device drivers for Windows CE is very similar to creating them on other operating systems. The operating system provides a handful of driver models that define the functions your driver must expose and their operation. What sets Windows CE apart is the rich set of driver frameworks that it provides. These allow driver writers to concentrate on the hardware specific bits while the framework handles the common tasks like queue management and interrupt routing.
