近年来，单片微型计算机以其强大的生命力飞速发展，在工业控制、智能仪器仪表、智能化设备和家用电器等领域得到了广泛的应用，因而引起了各行各业的极大关注，有着广阔的发展前景。论文设计的是一个单片机控制多功能信号发生器。其设计目的是使学生通过这一实践环节，增强单片机扩展接口设计及其实际应用能力。本系统的软件可运行于DOS及Windows系列操作系统平台。完成的主要功能设计有：单片机所需平稳电压的获得，8K字节固化程序存储能力，七段数码显示器，3×4的12位矩阵键盘，波形产生与电压变换功能，具有8位精度的D/A转换功能，时钟电路与复位电路以及完成相关的软件设计。本系统以8031单片机为核心，配置相应的外围接口电路，用汇编语言开发，组成的一个单片机控制多功能信号发生器。硬件电路设计包括三部分内容：一是电源部分设计；二是系统扩展，即单片机内部的功能单元（如ROM、I/O、定时/计数器、中断系统等）容量不能满足应用系统要求时，必须进行片外扩展，选择适当芯片，设计适当电路；三是系统配置，即按照功能要求配置外围设备，如键盘、D/A转换等。系统中的应用软件是根据系统的功能要求而设计的，可靠地实现了系统的各种功能要求。
In recent years, with its rapid growth as strong vitality, single-chiped micro computer has been widely used included but no limited in industrial control, smart instrumentation, intelligent equipment and household appliances, which causes great concern to all walks of life, which has broad prospects for development.
The design descrided in this thesis is a microprocessor controlled multi-function signal generator. It is aimed at enhancing students' capacity of design on a expansion of SCM and their practical application ability via practice courses.
The software of this system can run on DOS and family of Windows Operating Systems Platform.
The achievement of main functions:
Microprocessor voltage required for smooth access,
8 K bytes curing process storage capacity,
Seven sections of digital display,
3 × 4 of 12-bit Matrix keyboard,
Waveform generator and voltage transformation functions,
D / A converter functions with 8-bit Accuracy,
The clock circuit and reset circuit,
Other related software design.
The system is a microprocessor controlled multi-function signal generator, set SCM 8031 as the core, configuring the appropriate external interface circuit, developed by assembly language.
Hardware circuit includes three parts:
1, The design of power;
2, The system expansion, which is Off-chip expansion that must be performed to select an suitable chips and design an appropriate circuit while a capacity of the function of internal microcontroller units (such as ROM， I / O， timing / counter， interrupt system， etc.) can not meet the application requirements;
3, The system configuration. It's to allocate peripherals such as keyboards, D/A converter, ect. in accordance with the functional requirements.
The software in this system is designed according to the function of the system requirements to reliably achieve various functional requirements.
