TPYBoard development board construction and Alibaba Cloud service sending data

   What I bring to you today is the experience of using a test project of the TPYBoard V202 development board. The test item is to send the underlying hardware data to the server, and the data includes the product name, the MAC address of the WF module, and the temperature and humidity data.

 

     What is MicroPython ?

    MicroPython is a Python that can run on a microcontroller, that is to say, you can use the Python script

This language develops microcontroller programs.

    MicroPython is open sourced under the MIT protocol, and the licensee has the right to copy, modify, distribute and sublicense

profit. Designed by theoretical physicist George Damien of the University of Cambridge. Similar to Arduino, but MicroPython

More powerful.

    MicroPython is based on ANSIC, the syntax is basically the same as Python3, and it has its own parser and compiler

, virtual machines and class libraries. Currently it supports 32-bit based ARM processors such as STM32F405. That is

It means that the ARM processor STM32F405 can run the Python language directly, and use the Python language to control the microcontroller.

 

What is TPYBoard ?

    TPYBoard is based on MicroPython under the MIT license and made by TurnipSmart.

This MicroPython development board is based on the STM32F405 microcontroller and transmits data through the USB interface. Should

The development board has 4 built-in LED lights and an acceleration sensor, which can work normally at voltages between 3V-10V.

    The TPYBoard development board allows users to easily control various peripherals of the microcontroller through Python code, such as

LEDs, etc., read pin voltages, play songs, network with other devices, etc.

    The TPYBoard development board supports the direct operation of Python 3.0 and above, supports the gravitational acceleration sensor,

Support hundreds of peripheral accessories, support SWD programming firmware. Zero foundation can also flexibly master single-chip technology!

 

I encountered many problems during use, including the Python3 version, and the python2 version

problem, the problem of flashing the firmware of the development board, and the problem of the MAC parsing algorithm. To solve these problems, the editor will soon

The group owner, I’m tired of asking my friends, and the editor is here to thank you, the official group owner, and that kind friend.

     Then I don't waste time and go straight to the topic:

Attach the displayed effect: this is the data returned by the development board.

 

This is the json data received by the server.
