I don't know exactly what you need so let me tell you what we did: > We made a very simple model that lets you communicate with your Arduino using a firmware like Firmata, or a simple firmware made by us (see the class comment of the class Arduino for code examples). We also made a very rudimentary C code generator to translate Smalltalk into C and we linked it to the avr-gcc/avrdude so now we can program the Arduino board without leaving Smalltalk, which is very cool. Unfortunately, the translator is still very limited (I think even more limited than Slang) but we are using it to translate the etoys scripts and it's good enough for our purposes. > > > I search more links about pic, electronics and gui with drag and drop to program this electronic's component for kids.

FWIW, making a graphical interface shouldn't be difficult at all but the Etoys interface is being used with kids and it's quite good IMHO. > > > But i don't know your project i use your link > sorry http://tecnodacta.com.ar/gira/projects/physical-etoys/ is my last tool > > > You'll find there the latest version of Physical Etoys, we are soon to release a new version with a lot of improvements.

We usually don't use Pharo to develop Physical Etoys because, you know, Etoys doesn't run in Pharo. However, I would like to ensure at least some of our project works in Pharo. If I can, I'll test it this week and maybe I'll write a ConfigurationOfArduino.

[Pharo-project] How to cook Mr Popatoe Process?
by StÃ©phane Ducasse Feb. 22, 2012

Feb. 22, 2012

Hi guys we have practically two solutions to cook a troll: - either I remove his email address from the list (2 min) a bit rude and unfriendly but this is a troll after all ;) - or we all create a nice rule: as Read I suggest you all to do 2 and keep you good energy for helping and not arguing endless with Mr Potatoe Process. Did you count the amount of time we all spent already on that? Have fun. Stef (I have my rule and I do not read such mail anymore).

[Pharo-project] Pharo VM
by Pavel Krivanek Feb. 22, 2012

Hi Stef, last year you mentioned that in January you want to brand our own VM. Is there any progress in this area? Will there be still two VMs (Cog and Stack)? Will we have own git repository? Cheers, -- Pavel

[Pharo-project] syntax error in StartupLoader script
by Ben Coman Feb. 22, 2012

Feb. 22, 2012

When using the following StartupLoader script StartupLoader default executeAtomicItems: { StartupAction name: 'Shared Package Cache' code: [ MCCacheRepository default directory setPathName: 'C:\Apps\Smalltalk\!Shared-Package-Cache'.]. }. I was getting a "syntax error in startup" that I could not identify (is it obvious to others?) This was due to the debugger not opening at the point of error since SmalltalkImage>>executeDeferredStartupActions catches the errors. So I hacked this as follows... deferredStartupActions do: [:each | [ each cull: resuming ] value. "btcdebug on: Halt do: [ :err| Smalltalk logError: '==== Startup Error: ', err description inContext: err signalerContext. errors add: err]"]. and then after a quit and restart the dialog "Syntax error: Unmatched string quote" appeared with... StartupLoader default executeAtomicItems: { StartupAction name: 'Shared Package Cache' code: [ MCCacheRepository default directory setPathName: _Unmatched string quote_ -> 'C:\Apps\Smalltalk\ So after removing "!" from the folder name the syntax error went away. So now a few questions... 1. Is there a simpler way to debug the startup scripts that I have missed? If not, can a StartupLoader>>test or similar be implemented which runs the same as at image start time but without the error catching in executeDeferredStartupActions, rather than needing to hack executeDeferredStartupActions as I did. 2. Is it reasonable to set a shared package cache in the startup like I have? Or are there some obvious problems with this that I don't see? I would like to avoid downloading all packages every time unzip a fresh image for testing. 3. Is the invalid "!" fixable (though of course I've worked around it)? I'll open any required bug entries. This was with Pharo-14333 / cogwin_r2522.zip / Windows 7. cheers, -ben

On my Nexus the Google Chrome browser *is* a WebGL app itself. Thereunder the V8 Javascript interpreter, which internally creates metaclasses e.t.c. The two core developers were Smalltalkers! :-) What can we expect from Google Chrome? Separation of Browser and JavaScript interpreter, the interpreter then resides on the server, sending OpenGL directly via websockets into the dumb OpenGL terminal. And Google Chrome interpreter also has some (new) programming languages under the hood, Smalltalk included. C++ interpreter already works.
