Self-learning infrared remote controller based on single chip microcomputer
Abstract: In today's society, the development of science and technology increasing people's standard of living is increasingly improved, in order to reduce the workload of people, so a range of household appliances, electronic device of the artificial control requirements is also more and more high, in this kind of situation, design a kind of integration of relatively high control system is inevitable. MCU integration too high, it has small volume, light quality, price cheap, less consumption such prominent characteristics, especially less consumption, and can make the power supply, small volume, light quality.
This design detailed introduces the hardware and software design method of learning remote control, and gives the specific each unit circuit design, programming and program flow chart. In the hardware design, selection of AT89S52 microcomputer as the core component models, and give peripheral circuit module such as infrared receiver module, infrared emission modules and external control module component design implementation. This learning infra-red remote adopts minimize application pattern design, simple circuit. So it can successfully learn a variety of infrared remote control device, and through the encoding 40 kHz carrier sent to learn memory signals. Realized to various infrared remote control of study, So as to realize the remote control for learning.
