Installation of Micropython .bin on a ESP8266

Before we can program and use a ESP8266 with python, we need to flash the firmware to MP - a Mirco Python environment especially designed for these microprocessors

We need to dowload the latest MP binary. At the time of writing:

wget https://micropython.org/resources/firmware/esp8266-1m-20220618-v1.19.1.bin

Then, we need to flash the software to the microcontroller. A script that helps us with this task is called esptool.py which can be downloaded from HERE:

esptool.py --port /dev/ttyUSB0 erase_flash
esptool.py --port /dev/ttyUSB0 --baud 460800 write_flash --flash_size=detect -fm dout 0 esp8266-1m-20220618-v1.19.1.bin 
    esptool.py v2.4.1
    Serial port /dev/ttyUSB0

We need urequests as well. This is no longer the stnadard in the mikropython default package:

https://raw.githubusercontent.com/micropython/micropython-lib/master/python-ecosys/urequests/urequests.py

Copy the files into the ESP with the help of ampy. Adafruit ampy that is. You can get it on arch linux / Manjaro distributions with

yay -S aur/adafruit-ampy

Now the files to be copied:

ampy -p /dev/ttyUSB0 put urequests.py
ampy -p /dev/ttyUSB0 put boot.py
ampy -p /dev/ttyUSB0 put main.py
ampy -p /dev/ttyUSB0 put inet.conf

Hopefully. Done.
