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


Note.png
TODO
Fritzing schematic of the blinking LED setup?


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 connected to an Arduino ; the Arduino itself being connected to several sensors/actuators.

Suggested sensors

Attached to the Modbus-capable Arduino

  • LED
  • light sensor
  • humidity sensor
  • temperature sensor

Other?

A LED matrix (managed through another arduino module?)

An LCD screen

Another idea: it can be interesting to allow light spot to be in front of the light sensor, so user can check if their light is on or off.

Bill of materials

Item Qty Total Cost (USD)
Raspberry Pi 1x 40.00
Arduino Uno 1x 30.00
Grove kit 1x 40.00
Micro USB cable 1x 3.95
4GB SD card 1x 7.95
USB 1A power supply 1x 5.95
USB A-B cable 1x 1.95
Wifi dongle (Netgear WNA1000M-100FRS)* 1x 20.00
TOTAL 150.00 USD
  • 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:
