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.�� If I can't get that in Smalltalk can it be added or what language should I move to?

I was referred to��

but I can't get it to work on RPi. ��

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? ��

Why can't I get Smalltalk goodies like I used to buy from Digitalk?�� 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.�� Dolphin has a somewhat easy way to add primitives.

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