Tutorial

EclipseCon 2013 Tutorial plan.

Goals

Show Mihini

• show key APIs such as logging, sched, airvantage, devicetree, (sms?)...
• show how it's easy to do I/O manipulation and wireless communication

Koneki for Mihini

• show how Lua is easy to edit thanks to LDT tooling
• show EE and remote development for Mihini

FUN!!!!!!

Key steps

Installation of Lua Development Tools

Download Lua Development Tools product (or get it from an USB stick provided to the participants), install the Remote Lua Development feature.

TODO
Retrieve and put LDT archives on USB stick

TODO
Put LDT p2 repo on the USB stick too

Hello World

• Write a first simple Lua application ("Hello World").
• Get familiar with the notion of Execution Environment, learn how to use Lua.
• Launch the application using the embedded JNLua VM
• Learn how to use the debugger

Installation of Mihini

Participants will compile and install Mihini on the Raspberry Pi based on the instructions available here

Compile Mihini source code

• Copy (git clone?) the sources of Mihini on the Raspberry Pi

TODO
Provide a copy of the git repo on the USB stick???

• Compile Mihini (and its Lua VM)
• Brief presentation of the defaultconfig ; tweak the few settings that will simplify development

First Mihini launch

• Start Mihini on the target
• Open a telnet connection on port 2000 to play with the agent's shell
  • a = 1
  • print(a)
  •  :agent.config.get('shell')

Hello World REMOTE

• Configure a new Remote System corresponding to the Raspberry Pi inside LDT
• Launch the previously written Hello World using a remote launch conf
• Do a remote debug

Setting up the Arduino

• First step will be to setup the arduino with a blinking LED

TODO
Prepare Arduino IDE archives (mac, linux, win) for the USB stick

TODO
Fritzing schematic of the blinking LED setup?

• Next is the instalation of the Modbus stack --> https://github.com/kartben/mihini-greenhouse-demo/tree/master/SimpleModbusSlaveExample

Remote run/debug

Log hello on the module.

Wireless code

Upload first data on internet using MQTT and AirVantage

Install application

Show how to install an application using mihini (and airVantage)

Hardware

The main hardware will be a Raspberry Pi (running Mihini) connected to an Arduino ; the Arduino itself being connected to several sensors/actuators.

Bill of materials

• this might not be the best option for the US market (sounds look it is way more expensive than in Europe?)

Ordering everything from Adafruit would be:

• Raspberry Pi: https://www.adafruit.com/products/998 - 39.95USD
• Starter pack for Arduino: https://www.adafruit.com/products/68 - 65.00USD
• Sensors (the ones provided in the budget pack)
• SD card: https://www.adafruit.com/products/102 - 7.95USD
• Power supply: https://www.adafruit.com/products/501 - 5.95USD
• USB A-Micro: https://www.adafruit.com/products/592 - 3.95USD
• USB A-B (the one provided in the budget pack)
• WiFi dongle: https://www.adafruit.com/products/814 - 11.95USD
• TOTAL: 135USD
