Multifunctional controller

Abstract

The invention provides a multifunctional controller based on a single-chip microcomputer dsPIC33EP512MC806. The multifunctional controller is provided with 19 on-off inputs, 6 analog inputs, 5 counter inputs, 18 on-off outputs and 6 PWM outputs and provided with LINKPORTs, RS232 and 485 communication interfaces through which the multifunctional controller can communicate with an upper computer and can be in cascade connection with a lower computer. The multifunctional controller further has the advantages of chip protection, signal isolation, interference resistance, miniaturization, high reliability, low cost, simple software programming and rapid grasping. The multifunctional controller can be used for automatic smoke alarming of indoor space such as residents, hotels and offices, and can automatically control room temperature and give out anti-theft alarms and remotely and wirelessly control household appliances through a mobile phone. The multifunctional controller can further serve as an experimental platform for the single-chip microcomputer application technology in undergraduate teaching of institutions of higher learning, can be used for design and manufacture of a small application system, can be sold in an external member form, can be used for professional skill competitions, curriculum design, graduation design and the like, and can achieve control over multiple functions and research and development of scientific research projects.

Description

technical field [0001] The invention belongs to the technical field of single-chip microcomputer experimental teaching and single-chip microcomputer-based control, and relates to a multifunctional controller. Background technique [0002] At present, in the field of experimental teaching technology, as single-chip microcomputer teaching, it is generally based on MCS-51 single-chip microcomputer, AVR single-chip microcomputer or ARM single-chip microcomputer to develop a multi-functional controller. The experimental instruments of the MCS-51 series have been greatly developed, which makes the experimental system of the MCS-51 series in colleges and universities quite complete. However, with the continuous development of single-chip technology, the application field of MCS-51 series has been very limited. As a beginner's entry-level experimental study, it is not bad, but it is still lacking in the cultivation of innovative talents. The functions of MCS-51 single-chip microcom...

Problems solved by technology

However, with the continuous development of single-chip technology, the application field of MCS-51 series has been very limited. As a beginner's entry-level experimental study, it is okay, but it is still lacking in the cultivation of innovative talents.

MCS-51 single-chip microcomputer and AVR single-chip microcomputer have insufficient functions, and their resources are not enough in many occasions.

The ARM microcontroller development platform involves an operating system and complex software
