一、前言在学习、开发单片机系统时,常常需要硬件仿真设备,用于加快学习和开发的进度,但此类设备对单片机数量、种类和固定外围电路有所限制,并且价格较贵。而联合运用仿真软件Proteus和单片机开发软件环境Keil uVision构建单片机虚拟实验室,在没有硬件实物的环境下虚拟建立了一个硬 I. Preface When learning and developing SCM system, hardware simulation equipment is often needed to speed up the learning and development progress. However, such devices have limitations on the number, types and fixed peripheral circuits of SCM, and are more expensive. The joint use of simulation software Proteus and SCM software development environment Keil uVision microcontroller to build a virtual laboratory in the absence of physical hardware environment to establish a virtual virtual
