Make Controller, mchelper 2.0 and /serial/ Issues

I’ve been attempting to hook up a serial GPS device to my Make Controller and read in data using OSC commands from mchelper prior to interfacing it with AS3 (as an aside, it’s really nice to be able to do this with the new version of mchelper). While I’ve been able to write to the serial port successfully using both /serial/char and /serial/block, reading from it always yields some sort of disaster.

Starting Over with the Make Controller + AS3 - Part 1

MakingThings just released a bunch of software updates involved with Flash and the Make Controller that nullifies a lot of my previous work with AS3 and flosc. While some of the components still seem a bit buggy, they represent some major improvements. The best news to come out of this round of releases is that the flosc socket server can now be ditched (sorry, Ben Chun) in favor of connecting to the Make Controller using a new version of mchelper. Additionally it is now possible, from Flash, to connect to a board using either USB or Ethernet. As a result, I’m starting my series over to take these latest developments into account.

AS3 + Make Controller Important Update (AKA Not Part 5)

As those of you that have been reading along with the series might extrapolate, this post is supposed to be Part 5. However, given some things that I’ve discovered in the Fwiidom AS3 implementation as well as some issues in the MakingThings AS2 classes, which I then ported to AS3 and in the process propogated those bugs, this is now an update on some progress made with some collaboration and refactoring.

Getting Started with AS3 and the Make Controller - Part 4

Doing Something “Useful” With Sensor Input

In Parts 1-3, we spent some time examining the basics of the Make Controller, OSC and how it works with (or in some cases doesn’t work) ActionScript 3. Now, we can start to do some things that might actually be construed as being useful for a project. To start, let’s get the hardware set up by hooking up a light sensor to analogin0. With that done, we can write some code to use the input from the light sensor as it detects ambient light levels to control the opacity of a sprite on the stage of our SWF.

Getting Started with AS3 and the Make Controller - Part 3

Please be sure to read Part 2, and download the classes from that example otherwise the following example will not work as expected.

This article will cover how to read OSC messages that are sent from the Make Controller into FLOSC and then into Flash using the modified FWiidom classes. Before getting started, this is where I have to point out that the manner in which the Flash Player receives the XML converted from OSC is by polling FLOSC, which is far from ideal. Polling is an inefficient and wasteful way of checking to see if any state has changed on the controller. This, however, is the way that OSC works - by querying the connected device to determine if the state of any inputs has changed. I’m not sure if this characteristic applies to the Make Controller in general, if for example, using other protocols over USB, but I have a feeling that it doesn’t. I’ll have to look at some of the code written for the controller in other languages and also read up on OSC to determine if this is the case. In any case, we’re stuck with polling in ActionScript.

Getting Started with AS3 and the Make Controller - Part 2

In attempting to wire up a slide potentiometer to the Make Controller and poll for its values using AS3, which was supposed to be Part 2 of this series of articles, I ran into a significant problem. (To understand what exactly I was trying to do, check out Getting Started with AS3 and the Make Controller - Part 3 - Determining Input Values.) After coding up my example for the article in AS3, I expected that when publishing the .SWF, everything would be working, right? No, of course not. That would be far too easy. After checking and double-checking my code thinking that I probably just did something stupid while working on it late at night, I was stumped. I slept on it and still couldn’t figure it out. After much frustration, I opted to revert back to AS2 to see if maybe there was an issue with the potentiometer and re-wrote the example using AS2 and the MakingThings AS2 classes and it worked a treat.

Getting Started with AS3 and the Make Controller - Part 1

A couple months back I picked up a Make Controller from Making Things to do some experimentation with Flash Media Server and physical computing. I’m just now getting around to writing up my experiences about getting set up with the Make Controller. While the tutorial on the Making Things site was great for getting started using AS2 with their .mxp extension, it didn’t offer up anything on how to get started with what I really wanted to do, which was a project that would benefit from the performance of AS3 and Flash Player 9, so I had to take matters into my own hands.
