基于Proteus和Keil接口的虚拟波形发生器仿真

Simulation of Virtual Function Generator Based on the Interface Between Proteus and Keil

单片机的开发需要良好的软件环境支持,但目前对外围设备的仿真仍然是仿真软件的一个薄弱环节。基于Proteus强大的微处理器仿真功能和丰富的元件仿真模型,运用Keil作为软件调试界面,提出了新的虚拟波形发生器的仿真方法。虚拟波形发生器使用常用的AT89S52芯片作为微处理器,加上外围电路设计,通过VSM虚拟示波器,可以逼真地观察信号波形。这种基于Proteus和Keil软件接口的仿真方法在虚拟仪器的教学演示和实际设计等方面具有很大的辅助作用。

The development of single chip microcomputers needs favorable software sustainment. Nowadays the simulation of the peripheral equipment is still a link of the simulation software. Based on the powerful function of simulation on the MCV and series of simulation models for devices in Protues, using Keil as the software debugging interface, a new way was provided to simulate the virtual function generator. The virtual function generator was established by using one commonly-used chip named AT89S52 as MCU, and together with some other devices, by using virtual oscilloscope, signal waveform can be observed realistically. This simulation method based on the interface between the software Proteus and Keil is very helpful to demonstrate the virtual instrument in classroom and practical design of circuit.
