This article mainly introduces the relevant knowledge of "how to quickly realize the family intelligent control platform by using the single-chip microcomputer". The editor shows you the operation process through the actual case, the operation method is simple and fast, and the practicability is strong. I hope this article "how to use single-chip microcomputer to quickly realize family intelligent control platform" can help you solve the problem.

Realization of web Server based on 0x01 single Chip Microcomputer

Several articles about using single-chip microcomputer to realize web server can also be found through baidu, but a more detailed implementation method has not been found. Here, there are two ideas that can be completed, one is wired lan module, such as w5500, this module itself has some functions of web service, which is relatively simple to use, but can only be accessed based on lan. The other is through stm32 and other single-chip computers, with the network module to complete. At present, the easiest way I can think of is to implement it in stm32+esp8266.

Based on the first method, I think it is greatly affected by the performance of the module, limited by the module, and has no sense of development. So consider the second method. In this method, someone uses arduino to do it, which is programmed based on c. In addition, consider using micropython, which can be implemented directly with python. Tpyboard V202 is still used here.

Realization of Home Intelligent Home Control platform by 0x02 Simulation

Because I didn't think about how complicated the experiment would be, I just wanted to simulate the effect, so in the whole process of the module, I chose the tpyboard v202 development board as the main control board and used a light-emitting diode to simulate a desk lamp (in reality, a relay can actually be used to control the power on and off of other devices), and a small DC motor plus a mini fan blade is used to represent the simulated fan. The whole implementation also uses a transistor (S9014 # NPN) to control the DC motor.

Construction and connection of 0x03 hardware

1. The use of light emitting diodes

Light-emitting diode is relatively easy to use, directly looking at its two "legs", the long one is the positive pole, and vice versa.

0x05 program download test

Using the MicroPython File Uploader tool, download the source code to v202.

Tool download address: http://tpyboard.com/download/tool/170.html

1. Connect v202 to the computer using the usb cable, open the device manager and view the loaded port. Mine is COM44.

"if the driver installation fails, you can download the driver for CH340 and install it manually.

Download address of CH340 driver: http://tpyboard.com/download/drive/163.html

2. Open MicroPython File Uploader to select a port, and click * * Open * *.
