Getting Started with Micro Python for ESP8266

Sharing is caring!

Micro Python is nothing but a re-implementation of Python version 3 aimed at microcontrollers and embedded systems.
Installation of Python on Windows
Ensure that you have installed the latest version of Python 3.7.X on your computer. If not, follow the below instructions for Python 3.7.X installation.

  1. From the Python Downloads page: Download the installation file.

Installation of uPyCraft IDE

  1. Download uPyCraft IDE and install it from the link.
  1. A few seconds after downloading, you will see a similar file (uPyCraft_VX.exe) in your Downloads file.
  1. Double-click the downloaded file. A new window pops open with the uPyCraft IDE software.

Note: This is only for ESP8266. If you use different board then download as per your board specification.

Serial Port in IDE:

  1. Connect the NodeMCU through USB or ESP8266 to your system via CP2102.
  1. Go to Tools, followed by Serial, and choose your ESP8266 COM port.

  1. Note: If you could not see your COM port, it means that you don’t have a proper driver. ESP8266-NodeMCU board makes use of CP2102 driver to download CP2102 driver. You can download the CP2102 drivers from the silicon labs website.
  1. After installation, restart the uPyCraft IDE and now you should be able to see the COM port in the Tools menu.

Select board:
Go to Tools > Board. This tutorial is applicable only if you are using the ESP8266. So ensure that you choose the “ESP8266” option:

Just Choose the Following Option
Board – esp8266
Burn-addr - 0x0
Erase_flash– yes
COM – comport number
The primary choice is Users
Firmware: Choose “Users” and select the ESP8266 .bin file that was downloaded earlier.
After clicking the “Choose” button, go to your Downloads folder and choose the ESP8266.bin file.
Once all the settings are selected, hold the “BOOT/FLASH” button in your ESP8266 board.
While holding the “BOOT/FLASH“, click the “ok” button in the burn firmware window.

Once the “EraseFlash” process begins, the “BOOT/FLASH” button can be released. After a few seconds, the firmware flashes into your ESP8266 board.

Note: If the “EraseFlash” bar is not moving and you are seeing an error message that says “erase false“, it denotes that your ESP8266 was not in flashing mode. You have to repeat all the steps mentioned earlier and hold the “BOOT/FLASH” button once again to make certain that your ESP8266 is in flashing mode.
