IIC总线的四路舵机控制系统研究

摘要

介绍了一种基于IIC总线的四路人工控制舵机系统,系统采用周期内多次采样法,由单片机产生控制舵机的PWM信号,通过人工旋转电位器控制舵机转角,最后进行了Protues软件仿真和现场测试实验,实验结果表明,系统抗干扰强,能很好地满足设计要求.%Four steering servo control system based on IIC bus is researched in this paper. This system adopts method of multiple sampling in one period to generate PWM. The angle of servo is controlled by rotating potentionmeter. Finally,Proteus simulation and experiment is done. The result shows that the system has a reliable structure and can meet design request.
