Introduction - If you have any usage issues, please Google them yourself
First of all, introduce a number of device drivers on the background information, general norms and terminology. Then, we have to discuss device driver API, and one by one to explain API contains a function. We also discussed the buffer zone, the device driver through the buffer zone, handle calls and data applications. Thereafter, we will discuss the device driver with the various data flow methods, is actually a device driver handle data in the buffer process. Finally, we will use the December 2005 release of an updated version of VisualDSP toolset to UART device driver as an example, the presentation device driver on the many concepts.
