驱动程序的结构,应用程序经过系统调用，进入核心层，内核要控制硬件需要通过驱动程序实现，驱动程序相当于内核与硬件之间的“系统调用”。-Driver structure, the application through system calls, into the core layer, the kernel need to control the hardware driver implementation is equivalent to the kernel and hardware driv

本书集中精力于Linux 设备驱动本身，理解 Linux 内核模块、Linux 设 备驱动的结构、Linux 设备驱动中的并发控制等内容-Book to focus on the Linux device driver understanding of the Linux kernel module, concurrency control structure of the Linux device drivers, Linux device driver

这个是永磁无刷直流电机的本体结构和控制电路的联合仿真，既可以设计电机的结构，又可以搭电机的控制系统。-This is the body structure of the permanent magnet brushless DC motor and control circuit co-simulation, both the structure of the motor can be designed, they can take control of the motor system.
