摘要
信号发生器又称信号源或振荡器,在生产实践和科技领域中有着广泛的应用。该文在了解8086CPU芯片的基础上,应用8086的接口芯片设计一个信号发生器,根据外接16位编码,利用8253的方波发生器的频率改变信号发生器的频率,用LED发光管显示其设定的闪烁的频率,使用逻辑开关进行频率的改变。
The signal generator also known as the signal source or oscillator,in the production practice and science and technology has a broad application.In this paper,in understanding 8086CPU chip,based on the 8086 application interface chip design a signal generator,according to an external 16-bit code,use of the square wave generator 8253 changes in the frequency of the frequency of the signal generator,with LED LED display the set given the frequency of flashing,and then use the logical switch frequency changes.
