Tutorial
EclipseCon 2013 Tutorial plan.
Tutorial material is hosted at https://github.com/SierraWireless/eclipsecon2013-m2m-tutorial How to get it:
- git clone
- download zip file:
https://github.com/SierraWireless/eclipsecon2013-m2m-tutorial/archive/master.zip
Once you've got the repo locally, you can browse tutorial material:
Especially:
- *slides*: index.html at the root of the repo
- *Code Solution*:
lab/mihini-tutorial-step3/
(That's an Koneki project, so can import it directly in your IDE)
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 to reproduce the tutorial
Installation of Lua Development Tools (all-in-one bundle)
M3DA Server
tcp://m2m.eclipse.org:44900
Run you own instance:
End user android application
Running Mihini on RaspberryPi
Compile and run Mihini manually
Available instructions here
- Copy (git clone?) the sources of Mihini on the Raspberry Pi
TODO
Provide a copy of the git repo on the USB stick???
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
Setting up the Arduino
Exact Demo arduino code is in -->
instalation of the Modbus stack --> https://github.com/kartben/mihini-greenhouse-demo/tree/master/SimpleModbusSlaveExample
Hardware
The main hardware will be a Raspberry Pi (running Mihini) connected to an Arduino ; the Arduino itself being connected to several sensors/actuators.
