Design Of The Experimental System Based On IAP15F2K61S2 MCU

With the development of modern electronic technology, electronic devices are toward intelligent development, which led to the large number of applications of SCM technology in different areas, a variety of general and specialized SCM model is produced by many domestic and foreign manufacturers. There have been several widely acclaimed classic model in 30 years of microcontroller development, its structure design, has been guiding the development of SCM direction. Atmel designed of the 8051 series microcontroller is one of them. The model of SCM with its advanced design, superior performance, high reliable and high price, rapid spread of the market at home and abroad, and become the most popular models in the domestic and foreign technical field of single chip computer application in quite a long period of time, which has led to the development of single chip computer application technology course in engineering field. The experimental system of single chip computer with 8051 technology as the core is also entered into the engineering college. With the rapid development of single-chip technology, the traditional 51 series gradually fade out of the market, a variety of enhanced version of the microcontroller began to appear and apply in all walks of life. But at present most of the institutions of microcontroller development system is based on traditional 51 series, for example, AT89C51, AT89S51 etc which is not gradually synchronized with technology development and the market demand, so this will inevitably impact on personnel training, using new MCU design a development system becomes necessary.This design will take the macro crystal STC microcontroller IAP15F2K61S2 as the core design of a microcontroller experimental system. The experimental system is designed in a modular form, including the core board module,12C module, serial/ parallel ad module, keyboard module, communication module, static display dynamic module, display module, LCD display module and so on. The core board can choose 3.3V or 5V power supply. Each module has reserved interface, which can use the core board to finish the designated teaching task based on each other, and also can connect the target board independently.. According to the hardware module and teaching project module, the software modules are developed, including the control driver, AD/DA program, RS485 RS232/communication program, LCD display program, etc.This design should meet the requirements of the application of electronic specialty for MCU application technology, and will provide a platform for the teaching of the course of the college to meet the needs of the society and the professional needs of the hardware. The SCM experimental system using macro crystal IAP15F2K61S2 MCU of the IAP and ISP function of the microcontroller can have the function of professional simulator which can be directly observed every step of the procedure corresponding to the corresponding hardware condition, which can provid great help for teaching and training students. Each module of the design can be used as the core board, and it can be used as the function module in the intelligent control system and the intelligent electronic equipment. The main function of this design is to complete the teaching tasks of the single chip microcomputer application technology course and the training and use of the various training projects and various electronic competitions. It also has practical value and practical significance for the occasion such as scientific research projects in colleges.. This paper introduces the module structure, development process, design idea and related hardware structure and software design of the system in detail in this paper.
