TPYBoard development board construction and Alibaba Cloud service sending data [Copy link]

Today I will share with you my experience of using a test project on the TPYBoard V202 development board. The test project is to send hardware underlying data to the server, and the data includes product name, WF module MAC address, temperature and humidity data.

What isMicroPython? MicroPython is Python that can run on a microcontroller, that is, you can use the Python script language to develop microcontroller programs. MicroPython is open source in compliance with the MIT protocol, and the licensee has the right to copy, modify, distribute and re-authorize. It was designed by George Daming, a theoretical physicist at Cambridge University. It is similar to Arduino, but MicroPython is more powerful. MicroPython is based on ANSIC, and its syntax is basically the same as Python3. It has its own parser, compiler, virtual machine, and class library. Currently, it supports 32-bit ARM processors, such as STM32F405. That is to say, Python language can be run directly on ARM processor STM32F405, and Python language can be used to control the microcontroller. TPYBoard is a MicroPython development board made by TurnipSmart based on MicroPython under the MIT license. It is based on the STM32F405 microcontroller and uses the USB interface for data transmission. The TPYBoard development board has four built-in LED lights and an acceleration sensor, and can work normally with a voltage between 3V and 10V. The TPYBoard development board allows users to easily control various peripherals of the microcontroller through Python code, such as LEDs, read pin voltages, play songs, and connect to other devices.

TPYBoard development board supports direct running of Python 3.0 and above, supports gravity acceleration sensor,

supports hundreds of peripheral accessories, and supports SWD firmware burning. Zero foundation can also flexibly master single-chip microcomputer technology!

[font=微软雅黑,I encountered many problems during use, including the problem between Python3 version and Python2 version, the problem of flashing the development board firmware, and the problem of MAC parsing algorithm. To solve these problems, I almost annoyed the group owner and my friends. I would like to thank the official group owner and that kind friend.

Then I won’t waste time and get straight to the point:

This is my friend’s TPYBV202.

The code is as follows:
