在NiosII的开发过程中,硬件抽象层提供多种一般模式类设备,使得开发者可以高效的在系统中添加并使用这些设备。然而对不属于一般模式类的新设备的使用将不能按照原有的设计方法进行系统开发。为此,需要根据NiosII内部总线规范提供一个设备驱动,并按照SOPCBuilder要求集成到硬件抽象层中。通过设计并集成非字符型液晶显示模块得出结论:任何非一般模式类设备均可加载到NiosII系统中并能正常工作。
In the development of NiosII, hardware abstraction layer provides a variety of general mode class devices, so that developers can efficiently add and use these devices in the system. However, the use of new equipment that does not belong to the generic pattern class will not be systematically developed in accordance with the original design method. To do this, a device driver needs to be provided in accordance with the NiosII internal bus specification and integrated into the hardware abstraction layer as required by SOPCBuilder. By designing and integrating non-character LCMs, it is concluded that any non-generic mode device can be loaded into the Nios II system and work properly.
