基于MSP430单片机的抛物线映射混沌电路实现
资料介绍
在对抛物线映射混沌方程的分叉图、数值仿真分析的基础上,提出了仅用MSP430F169单片机实现混沌时域波形的方法.为了使方程能够在单片机上实施相同的定点迭代运算迭代过程,通过设定单片机的控制寄存器、数模转换器,采用比例扩张变换和移位的方法编写C程序,编译后下载到单片机中,将单片机的P6.6引脚连接到示波器探头观测到硬件实现的混沌信号与MATLAB数值仿真的结果完全一致,充分说明本设计的可行性,其为实现基于在MSP430F169单片机的保密通信提供了参考.
The paper analyzes the bifurcation diagram and MATLAB simulation of parabolic-mapping chaotic equation,and then puts forward a method to realize the chaotic time- domain waveform by only using MSP430F169 MCU. The same fixed-point iteration with parabolic- mapping chaotic equation on MCU can be realized by setting the control registers and digital analog converter,and adopting proportional expansion method to design C program,which should be downloaded after compiling and fixed into the microcontroller. The chaotic signals of hardware implementation can be observed when the MCU P6. 6 pin is connected to the oscilloscope probe. The result is totally the same as that of MATLAB numerical simulation,which fully illu...
