  In recent years， single-chip micro-computer with its strong vitality of rapid development in industrial control， smart instrumentation， intelligent equipment and household appliances， and other fields has been widely used and therefore aroused great concern to all walks of life， with wide Development prospects. Papers design is a microprocessor controlled multi-function signal generator. The design objective is to enable students through this practice， enhance the expansion of SCM and its practical application interface design capacity. The system software can run on DOS and Windows family of operating systems platform. Complete the design of the main functions: microprocessor voltage required for smooth access， 8 K bytes curing process storage capacity， Qiduan digital display， 3 × 4 of 12 matrix keyboard， waveform generator and voltage transformation functions， with eight Accuracy of D / A converter functions， and reset the clock circuit circuit and the completion of related software design. SCM 8031 to the present system as the core， configure the appropriate external interface circuit， with assembly language development， consisting of a microprocessor controlled multi-function signal generator. Hardware circuit design includes three parts: First， the power of the design of the system is expanded， that is the function of internal microcontroller units (such as ROM， I / O， timing / counter， interrupt system， etc.) capacity can not meet the application requirements The need for expansion outside the film， select the appropriate chips， the design of appropriate circuit; Third， the system configuration， that is， in accordance with the functional requirements of targeted peripherals such as keyboards， D / A converter， and so on. System of software is based on the function of the system requirements and design， to achieve a reliable system of functional requirements.
