• Lolin32 board

This repository contains for the ESP32:

• library's
• stubs
• unit tests for libs and asyncio
• application (neopixelklok)

I used to work with the esp8266, but was not satisfied with the stability of the platform (file system corruption etc).

Currently I focus on the esp32 development, as this is a very promising platform. Hopefully the porting of micropython to the esp32 platform will proceed.

As development tools I use ubuntu 16.04, minicom and Sublime Text3 and krusader for ftp file transfer. Sorry no windows support!

1. install plugin ftpsync in Sublime Text3.

When configured correctly Sublime Text3 will upload the file to the board on each save.

The root of the target file system should contain the file ftpsync.settings. See file lolin32/ftpsync.settings

2. assumed here is that the target board has a copy of all files in lolin32/.

After resetting of the target device, main.py will:

• connect to an AP (wifi.connect2ap())

• Within a try except block an unit test or an app is started

• In case of an exception (or pressing ctrl-C) the ftpserver is started

• In Sublime Text3 use plugin ftpsync

• in the root of the lolin32 tree place file ftpsync.settings

• When saving a file in sublime, the file is automatically uploaded to the board.

• pressing ctrl-D or do a hard reset for the next cycle

For rapid development I use a linux host machine for development. Ubuntu 16.04 to be precice. Sorry, but the instructions given here are only for linux, not for Windows!

readme:

for example:

cd 
mkdir bin
# add next line to .bashrc:
export PATH=$PATH:~/bin
# Add the micropython executable to ~/bin 

• Create file ~/.config/sublime-text3/Packages/User/micropython.sublime-build

with content:

{
    "cmd": ["/home/anton/bin/micropython", "$file"],
    "file_regex": "^[ ]*File \"(...*?)\", line ([0-9]*)",
    "selector": "py",
    "env":{"MICROPYPATH":"/data1/workspace/micropython/esp32/lolin32/stub:/data1/workspace/micropython/esp32/lolin32lib"}
}

Replace the path's with the actual paths as used by you.

Already done: see lolin32/stubs!

Note that the sublime-build for micropython will add the stub first on the micropython PATH

A fresh board, just flashed with micropython, but with a blank file system.

How to get files on the board?

See esplorer for this.

As soon as the board is connected to the wlan, and the ftpserver is running: copy with krusader all files in lolin32/ to the target file system

In minicom disable the hardware handshake, otherwise ctrl-C or ctrl-D will not work:

• within minicom press ctrl-A z (minicom command summary)
• O (configuration)
• Serial port setup
• D (Hardware Flow Control: no)
• G (Software Flow Control: no)
• Save setup as dft in configuration
