51 microcontroller development environment construction method

Preface

From aerospace to children's toys, everything with a little bit of intelligence is inseparable from the presence of microcontrollers... At the beginning of this article, we learn the relevant knowledge of microcontrollers. We use the microcontroller developed by Puzhong Technology A7 development board, this development board is equipped with two chips, STC89C52 or STC89C516. This microcontroller belongs to the 8051 series and STC8 series of microcontrollers. As an entry-level microcontroller, the 51 microcontroller is not only widely used in teaching experiments, but also very useful in practical projects. widely.

1. Basic knowledge

1. What is a microcontroller?

The microcontroller is a single-chip microcomputer, which is composed of a central processing unit (CPU), data memory RAM, program memory ROM, input/output devices (keyboard, display screen, etc.) integrated into one chip.

2. What can a microcontroller do?

The function of the microcontroller is well explained at the beginning of the preface. Anything with a touch of intelligence is inseparable from the microcontroller. Especially now that the Internet of Things is developing in full swing, the microcontroller has ushered in a new spring. Currently, smart microcontrollers are inseparable. Instruments and smart small appliances are mostly connected to the Internet of Things platform through 51 microcontroller + wireless module, and then the smart devices can be monitored through the front end.

3. Why should we learn microcontroller?

After learning the microcontroller, you can make some interesting small creations by yourself, improve your hands-on ability and practical ability, and participate in electronic competitions, which is very helpful for college students to find jobs after graduation, and they may accidentally change the world.

4. Introduction to development board
