The main issue is that what I want is an Xcode projet that is clean. This is doable, the current Xcode project in the source tree is crappy with locations not well defined etc. Fixable. But I need to know what to do first.
Hilaire told me to look here.
I've got an Arduino Uno. In fact, I did a number of ISA (! old) cards, and interfaces, like oscilloscope board, ... I can hook that back to the Arduino and then in turn make some Pharo classes (maybe with FFI - I know some people did stuff but not on OSX) to take the data in. The fun part would be the visualization of an iPad remotely.
I saw something in Ghent (I am from Belgium). I'll try to go.
Then in Lille, there is also something. I'll go as well.
Depends in fact on how well I recover from my current eye surgery. I am locked in my home/office for 4 weeks due to retinal detachment :-( - Things should be okay by then.
For the record, I am a civil engineer and am self employed since 2000.
