Web-based code editor for WiFi + MicroPython enabled microcontrollers

Uses Cloud9 Ace editor for code editing

Has an integrated WebREPL console

Developed and tested on ESP32, but should work on other boards too

1. Flash a recent version (1.17+) of MicroPython to your Controller (https://micropython.org/download)
2. Copy contents of /weditor and lib/microWebSrv.py to the root of Controller's file system

$ cd micropython-web-editor
$ ampy --port /dev/ttyUSB0 put weditor /weditor
$ ampy --port /dev/ttyUSB0 put lib /lib

3. Setup WebREPL (optional) On your Controller run:

import webrepl_setup

4. Update boot.py

print("Activating network")
import network
wlan = network.WLAN(network.STA_IF)
wlan.active(True)
wlan.connect('YOUR_SSID', 'YOUR_PASS')

print("Starting webrepl")
import webrepl
webrepl.start()

print("Starting IDE web service")
import weditor.start

5. Reboot Controller
6. Open controller's IP in your browser (make sure to use https:// scheme - https not supported)
7. Have a nice day

For easier file system operations (mv, rm, mkdir, df, etc.) MicroPython shell - instructions on this page

This project would not be possible without these exceptional projects

Cloud9 Ace code editor

MicroWebSrv

MicroPython's WebREPL

And most importantly: MicroPython

• File saving does not work well with large files yet
• This editor was mostly written and debugged using itself
• esp8266 does not have enough RAM to run all required components (yet)
• When using the IDE, Internet connection is required because Ace is hosted on cdnjs (to reduce storage requirements); but it's possible to bundle required ace.js files on Controller's flash (raise an Issue and I'll explain how to do it)
