摘要
鉴于目前在控制、电信与电子仪器领域对各种频率信号源的需求,采用性价比较高的STM32F103RCT6芯片,通过按键控制高性能的DDS芯片AD9910产生各种频率的信号,并通过LCD12864实时显示。详细阐述了该系统的硬件与软件设计,并对其中的关键部分、注意事项和采用工具等进行具体说明。最后对设计出来的信号源实时显示系统进行验证,结果表明该系统工作稳定,可以满足工程需求。
In view of the current demand for various frequency signal sources in the fields of control, telecommunications and elec-tronic instrumentation, a high cost-effective STM32 F103 RCT6 control chip is used to generate various frequency signals through the button control of the high-performance DDS chip AD9910 and real-time display through the LCD12864. This article describes in detail the system hardware and software design, and the key part, precautions and the use of tools for specific instructions. Finally the designed system is verified, and the results show that the system is stable and can meet the engineering needs.
