Mozzi versus rotary encoder

[Robin Parmar]

I am new to Mozzi and am trying to get it to work with a small library I use to handle rotary encoders. I am using an Arduino Uno and reverted to Arduino IDE 1.0.5-r2 after reading that might help compatibility. Basic Mozzi example sketches work fine. Pots and other sensors too.

My library MozziEncoder.cpp is based on Matthias Hertel's code, but I have modified it to support the push button feature of my encoders. Thus each encoder utilises a digital input pin (for the switch) as well as two analogue pins (for the encoder). In the library I have replaced millis() with mozziMicros(). The only Arduino functions in use are digitalRead() and pinMode().

I get no values out of the encoder at all. It is as though digitalRead() is broken.

Does anyone have a clue from this minimal account? My only alternative would be to post the entire library.

Hi Robin,

digitalRead() should work OK with Mozzi, it's in one of the examples>Mozzi>03.sensors>Piezo_Switch_Pitch.  Does your library rely on polling or waiting/counting cycles for a pin to change?  It's possible to work around it in Mozzi, if that's the problem.... though it might actually mean working around in your library to make it work in Mozzi.... let me know if that's barking up the wrong tree.

did you get it fixed?

if not, post the library!
