Topic: Position from encoders? Need help, will compensate! (Read 807 times) previous topic - next topic


Hi all,

I am a mechanical engineer and designer, but have no skills in programming what so ever...

For my next project i need to calculate relative positions based on the output from 6 rotary encoders, and preferably plot them on a computer.

Yes, I am talking about a CMM arm, and if you know what that is, then you`ll probably want one to  :P

I am able to sort the mechanics and most of the elecctronics myself, but I`m totally at loss with the coding...

Need help, will pay, within reasonable amounts that is...

Best regards

If it`s worth doing, it`s worth doing right!


In a former life I used to be a toolmaker, so yes CMM is familiar to me.

I can "probably" help you with your coding requirments if you would like to expand on them a bit more.

Cheers Pete.

"calculate relative positions based on the output from 6 rotary encoders, and preferably plot them on a computer."

Are these just  relative  pulse producing encoders or true position encoders indicating absolute position by output?
I have a  stable real time  ( interrupt driven) A and B output optical encoder ( relative position)  code and willing to share.

If you want real time interrupt driven application beware that Arduino can do two interrupt inputs "out from the box",
and more interrupts with minor software additions. But I am  not sure if 6 interrupts ( 12 inputs ) would work.
But it would probably work without interrupts, depending on your requirement.
