Really good job.

Answer to Netham45:
The stuff that took so long to type was: 'while 1 do led("I") sleep(1) led("<3") sleep(1) led("Omnimaga") sleep(3) end'.
Its not the most easy thing to do while filming the whole thing, and typing with one hand

Holy cow!
Amazing, Jim!

In case anyone wants it, you can find the Lua and the C (for the arduino) source code here: http://bwns.be/jim/arduino-ti.zip

Arduino takes Processing as code

Not C? Or can it also take C? I'm pretty sure it's Processing though.

Well, its Processing, but I think its valid C anyway :p

It's Processing then, and save it as .pde, not as .c

This is a bit off topic, but if you can control external hardware, can you also control external files on the calculator?

Jim Bauwens · « **Reply #23 on:** July 28, 2011, 01:05:48 pm »

If you mean files on the local calculator, you can access libraries with Lua.
If you mean something like an sdcard, no, because we can't get yet hardware input .
There is though a chance that you can connect an sdcard to the dock, but more research has to be done on it.

I meant can you get data from other lua files on the local calculator (i.e. level data, high scores, etc.)?

I know I'm a bit late, but wow. That video is epic.

Not really, the data has to be in the same .tns file, and then get retrieved with var.recall, which grabs a Maths activity variable and puts in in a Lua variable

Jim Bauwens · « **Reply #28 on:** July 30, 2011, 01:19:40 am »

Adriweb, you can also use math.eval to execute a function in a library document (not in the current tns file) and return stuff saved there.

Adriweb · « **Reply #29 on:** July 30, 2011, 01:29:01 am »

yep, but I think that if you have a lot of calculations to do, importing the variables in Lua then do all your calculations within lua (and then var.store() the final result) is much faster than doing all the calculations in a math.eval() call, as it's calling the math 'server' (as they call it) everytime ...

EDIT : but I think it's fine if you have only a few calculations to make
