Re: [Pharo-users] Any hope for Smalltalk on Raspberry Pi?

[stepharo]

First hello and welcome to Pharo.

Second can you be clear about what you want to achieve?


I have Squeak on a RPi but I don't know how to access any USB 
peripherals or how to make primitives to do so. I want to use RPi for 
controlling a microcontroller and processing webcam video for my robot.

That would be really nice.

If I can't get that in Smalltalk can it be added

I do not know RPi
the system can be extended
- adding a vm pluging (check the new blue book on my web page 
to get an idea)
- doing an FFI call (now I do not know the status of the FFI on 
rasp)



or what language should I move to?

I was referred to
http://car.mines-douai.fr/category/software/pharos/
but I can't get it to work on RPi.

What are the exact problems you face?
Because this is a bit short.


A major focus of RPi is to teach electronics but without access to the 
peripherals, Smallltalk is not useful.  But some access is available 
in Scratch which is built on top of Squeak so why can't I get access 
to that code directly instead of going through the Scratch changes file?

I do not know. May be this is just one pluging missing.
Did you check Phratch?



Why can't I get Smalltalk goodies like I used to buy from Digitalk?

You see:
- the world got more complex we provide vm for OSX, iOS, Windows 
(different flavors), rasp, android, linux (different flavors),
- second so far Pharo is free. Now you can help either by offering 
some time or putting money for a bounty on the table
- third we are really busy making sure that Pharo 5.0 is on time 
and robust.
With all the VM work, there must be a way to hook up C++ code like 
OpenCV to do real time video contours and other image recognition 
algorithms.
Forget about C++ the binary is not standard. You have to wrap the C++ 
library into a C program and you could used (now it changed because

we do not use nativeboost anymore).


Dolphin has a somewhat easy way to add primitives.

Pharo too.

You should read the uFFI draft documentation. Check the mail if was sent 
recently.


If Squeak all in one contains package bundles only for Mac, why not 
include essentials for RPi?

libusb seems to be plain C, so it would make a nice use-case for uFFI

http://www.libusb.org

There was an attempt at making a binding last year:

Would you mind providing a link?

Thanks,
Alistair

P.S.  Does anyone know what happened to Glenn Krasner post ParcPlace?
One of the nicer people I've met in my life and I'd be interested to
know.  Thanks.

Thanks for your reply.  I had found that page, but Stepharo had
mentioned a "new" blue book, so assumed it was something else.

Thanks again,
