Ardublockly ESP8266/ESP32 Micropython Fork

This project is about

  1. Adding Micropython code generator to Ardublockly
  2. Adding Micropython WebREPL to Ardublockly
  3. Uploading generated micropython code to ESP8266/ESP32 over the air

Goal is to make a web based Blockly programming enviroment for programming of ESPs OTA, without installation of any additional software to a PC

Proof of consept

this project demonstrates uploading generated Micropython code to a ESP8266/ESP32

To get the demo working do as follows:

  1. Get an ESP8266/ESP32 board
  2. Flash it with the MicroPython firware using esptool.py https://docs.micropython.org/en/latest/esp8266/tutorial/intro.html
  3. open micropython terminal and setup webrepl by typing: import webrepl_setup
  4. follow instructions for setuping webrepl
  5. (Using uPyCraft IDE) Change internal boot.py file on the ESP8266/ESP32 as:

boot.py

import network
import webrepl
ap = network.WLAN(network.AP_IF)
ap.active(True)
webrepl.start()
  1. reboot ESP8266/ESP32
  2. connect your PC to a ESP_XXXXXX Access point
  3. open ardublockly/index.html
  4. press connect on the top of the page
  5. click on Micropython WebREPL console down left
  6. it should ask you for a password you choosed during the webrepl setup
  7. after connection build your blockly code as you like, or leave it at the blink sketch as is
  8. and for a upload click on the big orange button
  9. if is everything connected it should give you a message, that blocks.py was sent
  10. reboot the ESP and the sketch should run

Ardublockly

Ardublockly is a visual programming editor for Arduino. It is based on Google's Blockly, which has been forked to generate Arduino code.

The ArdublocklyServer Python package initialises a local server to be able to compile and load the Arduino code using the Arduino IDE.

This is all packaged in a self contained executable desktop application for Windows, Mac OS X, and Linux.

Features

  • Generates Arduino code with visual drag-and-drop blocks
  • Uploads the code to an Arduino Board
  • Useful "code block warnings"
  • Compatible with a wide range of official Arduino Boards
  • Works on Windows / Linux / Mac OS X

Ardublockly is still under development and a few features are not yet implemented. A to-do list can be found in the TODO.md file.

Currently tested under Windows with Python 2.7 and 3.4 and in Linux and MacOS X with Python 2.7.

Cloning the repository

Please note that there are submodules in the repository that need initialisation. So, to correctly clone the Ardublockly repository:

git clone https://github.com/carlosperate/ardublockly.git
cd ardublockly
git submodule update --init --recursive

Installing

The desktop application is available for Windows/Mac/Linux and runs as a stand-alone executable that can be downloaded from the Ardublockly repository releases page.

You will also need the Arduino IDE version 1.6.x or higher.

Development builds

You can also test UNSTABLE development builds automatically generated every time an update is added to the GitHub repository:

Linux build Windows build Mac OS X build
Linux Build Status Windows Build status Mac Build Status
Download Link Download Link Download Link

"Core version" (Python server only)

If you prefer, the core software can be used by running only the Python server, which loads the web interface on your local browser (Chrome recommended).

Full installation instructions for this version can be found in this Github repository Wiki.

The quick version: Clone this repository, initialise all submodules, and execute:

python start.py

This will work on Windows, Linux (including ARM) and Mac OS X, with Python >2.7 or >3.4

Running

  1. Install Ardublockly.
  2. Install the Arduino IDE version 1.6.x or higher (latest version is always recommended).
  3. Run Ardublockly as defined in your installation method.
  4. Configure Ardublockly to locate the Arduino IDE following these instructions.

Online Demos

A demo of the latest release of Ardublockly main interface can be found in the following two links (to load the code into an Arduino it requires the full Ardublockly application to be downloaded and run on your computer):
