AutoIT & Phidgets, Robotics with AutoIT (How To)

[JustinMeyer]

I am planning on building a "How To - AutoIT & Phidgets" and am looking for direction on how to document it.

Phidgets are "Products for USB Sensing and Control" that can be utilized with AutoIT. They allow physical

interface, functions and events / input and output through COM in the case of AutoIT. Check out the

Phidgets page for more information, and go to Trossen Robotics if you are going to buy (Cheaper and Faster).

The image is a link to the video right after I was able to get

AutoIT and the 1063 Bipolar stepper controllers talking. I

am building a 3-Axis CNC mill.

I Know AutoIT and Phidgets are not the ideal way to go when

building a mill... its a learning experience.

Quick piece together of code used in video above.

Sorry its one blob, it keeps coming out like that.

So where should I start a thread or threads, examples or questions, as it will be both and more.

I have a few different Phidgets and will be progressing the capabilities and limitations with the

help of the forum.
