Getting Started with Scratch and PiFace Digital

Getting started with Scratch and PiFace

 

Scratch is a great graphical way of programming and can be set up so that it can read the inputs and control the outputs of PiFace.

 

This document contains the steps which must be followed to allow Scratch to talk to PiFace. If you download a premade image, then you don’t need to follow these steps as it has been made for you. However, if you want to use your own image then you will need to go through the following steps (detailed in the document). Note that this should only need to be done once, and is not needed each time you run Scratch.

 

These instructions are based on the steps detailed here: http://wiki.scratch.mit.edu/wiki/Mesh

  • Thank you for this comprehensive documentation. I followed it and it worked like a charm.

     

    At least, unless I tried to push it and used more than 5 output lines in scratch. Once I exceeded five output lines, my little scratch program was not able to get any of the attached LED's to life. I checked various blogs and forums, and there seems to be a limit which is known within the community.

    Unfortunately, this reduces the usability of the scratch interface for piface substantially. My son wanted to program two traffic lights - which is not possible.

     

    Any help available? Am I missing something important? If not, is anybody already working on that? How can I help (not being a hardware programmer myself)?
