基于VxWorks的智能多串口卡Simulink驱动模块开发

摘要

深入研究了S函数驱动模块的运行原理,给出了多串口卡驱动模块的具体开发过程.结合多串口卡的驱动模块实现,详细介绍了S模块的定义、实时环境下的条件编译和S函数各主要回调函数的功能,重点给出了S函数模块多实例复用的解决方案.通过定制RTW中的Tornado目标,介绍了生成VxWorks下多串口卡驱动模块的方法.%By research on the principle of S function driver model, the whole development process of simulink driver model is given. With the development of multiple channel serial card S function model, conditional compilation under real time environment and main callback functions are introduced. By customizing Tornado target in RTW, the method of generating intelligent serial card S function model under VxWorks is given.
