We need to download the firmware for our board, I'll use the esp8266 board as an example, but this circuit will work with all micropython enabled boards. We open the browser and go to the site micropython.org/download, here we look for the firmware for the desired board. Note that there are three versions for the esp8266 here that differ in flash memory. Select the current version and download.
To install the firmware, we need a special utility, we download it as a command
pip install esptool Next, enter the command to clear the board's memory
esptool.py --port /dev/ttyUSB0 erase_flashBut if you get an error, then enter the following command.
sudo chmod a+rw /dev/ttyUSB0Enter the command to flash the board. Check the port, the port speed should be 460800, if there are errors, then reduce the speed to 115200. And be sure to specify the path to the firmware file. We send the command and the board is reflashed.
esptool.py --port /dev/ttyUSB0 --baud 460800 write_flash --flash_size=detect 0 /your_path/esp8266-1m-20220618-v1.19.1.binDownload the editor, in which we select the port of our board and use the code from GitHub
pip3 install thonnyor
bash <(curl -s https://thonny.org/installer-for-linux)or
sudo apt install python3-tk thonny [On Debian/Ubuntu]
sudo dnf install thonny [On CentOS/RHEL & Fedora]For Windows or Mac
Open the program and first of all in the settings change python to micropython!
