摘要: 提出了一种简化嵌入式通用串行总线USB(Universal Serial Bus)接口应用程序设计的方法,其要点是在汇编编译器里增加处理“头文件”、“宏”和“代码生成器”的功能;以基于ET44M210微控制器的带USB接口的模拟信号采集器为应用实例,说明这一方法的优点和可行性.Abstract: A simplified method for USB(Universal Serial Bus) interface programming for embedded devices was proposed by adding some new functions (“head file”,“macro” and “code generator”) in the assemble compiler. A real application example “An analog signal logging unit based on ET44M210 with USB interface” was presented to illustrate the advantages and feasibility of this method.
