Learn how to install micropython on esp8266 board through Windows operating system in detail with screenshots

In this Tutorial we are going to now how to get started with MicroPython on ESP8266 boards by flashing and loading the MicroPython firmware on them. This tutorial is going to be in step by step process so that it would be easier for you you to understand and remember it for a long time. As ESP8266 as an inbuilt WiFi we can grab the advantages of it in communication. Before starting the tutorial let’s learn about what are the requirements below.

Requirements:

  • An ESP8266 board like nodemcu wemos D1 or any
  • A Windows PC With Python installed
  • Few software’s needed and their download links are provided below

Step1: Get started with Python installation

As the first step we need to install python to use the ESP tool which helps us to 2 flash and load MicroPython firmware on our ESP8266 board if your PC already has python installed skip this step. To download Python visit python.org and download the executable file for your operating system.

Add the path of the python in the path section of system variables in the environment variables  by default it is located at

Tip: If you dont know python path simply type the below code on command prompt

And also add the path of the pip to the environment variables found at

If you don’t know how to do that click on the below tutorial link.

After this to check whether everything is installed correctly open command prompt and type the below line of code to get the version of the python if installed.

so it displays the python version which you had installed. if it doesn’t display the version check the path and correct it.

Step2: Install esptool

To install esptool open command prompt and type the below command and make sure you need to connect to working internet to download the files.

Step3: Erase the flash of the ESP board

Before installing the MicroPython firmware on board we need to erase the complete flash memory on the board to get the clean installation.

Connect the ESP8266 board through the USB cable to the PC and run the following command to erase it

here replace the  “/dev/ttyUSB0″ with the port as we are using windows PC go to device manager and check the port of the board which looks as COMX.

Step4: Download the microPython firmware for ESP8266

Download the latest MicroPython firmware for your board through the following link  which is in .bin format.

Step5: Installing or flashing the Firmware on ESP8266

Now set the path of the command prompt to the path where firmware had downloaded. by default it will be saved in downloads folder so run the below command

To flash or install the firmware run the following command below

in the above code we need to change 3 values

  • port:  /dev/ttyUSB0  –>  COMX
  • baud: 460800 –> 115200   (default baudrate of ESP8266)
  • filename: name of the file you had downloaded

Example:

After typing  the above command hit enter to start flashing the MicroPython on the ESP8266, it takes few seconds and that’s it your development board is ready to run MicroPython.
