rotary encoder. up down object


    Mar 18 2008 | 11:46 pm
    hello all, im using an arduino with a rotary encoder into max, basically ive got digits going up one way and down the other. is there an object that can recognize the up and down movements? i think ive seen one but wasn't too sure..
    cheers

      You could cobble a solution together using either counter, accum, or IncDec (and probably several more that I'm forgetting. They each have the plusses and minuses.
      IncDec is the easy answer, but something based on counter might give you a more flexible solution.

      is there not an object that can recognize if the number value is going up or down?

      You could easily make an abstraction using [expr] or separate comparison operators (i.e. , =, etc.) to compare the value of the current input with the value of the previous input.

      Detecting whether a number is going up or down is trivial, but I don't think that that's really what you want.
      What is the arduino actually delivering? Some sort of delta based on number of clicks of the encoder? Is it a positive number if CW, and a negative number if CCW?

      actually it turns out im having some troubles in the arduino code, has anyone got one of these working in max?

      I've been using an arduino board with max happily, my current project involves controlling 4 servo motors through a max patch. I also did a project involving sending 6 integers to max from the analogue inputs on the arduino.
      I would guess that you should get as much as you can right at the arduino side of things before trying to tackle it in max. Maybe you could have two variables in the arduino code, for comparing the current and previous inputs from the optical encoder, and sending the difference to max, so -1 would indicate a negative direction and 1 a positive direction, and larger numbers may indicate some sort of force/speed.
      Do you have any specific questions pertaining to the arduino code?
