应用COG在降低基于单片机控制系统的人机交互成本同时,也使人机交互的编程复杂性加大,提出一种基于DSP驱动的可配置化COG界面显示控制方法;探讨了DSP驱动COG显示的意义及其实现原理,论述了方法中COG显示词汇信息库和页面信息库的可组态化组织方式,给出了父子页面和兄弟页面之间的切换原理,以两个信息库为基础,设计通用的驱动引擎来控制显示界面,实现人机交互的可配置化;最后以电动执行机构人机交互的实现为实例,进一步说明提出的可配置化COG显示控制方法的可行性和实用性。
Application of COG in control system based on single chip processor can reduce the cost of human-- machine interaction. However, the application also increases the complexity of the programs for human--machine interaction. In this paper, a control method for configurable COG LCM display based on the DSP was presented. The significance and implementation principle were discussed. And then the form of configurable organization in the control method was given to show the detail realization process. The switching method among father page, son pages and brother pages was presented. Based on the two information bases, a universal driven engine was designed to con trol the interface pages. At last, the implementation of human--machine interaction in electric actuator program was given as an illustration. The result shows the feasibility and applicability of the control method in COG display with DSP processor.
