Fork of scoreLight_Advanced by Alvaro Cassinelli

hardwareIO/CRotaryEncoder.cpp@44:46e25fa1669b, 2014-03-31 (annotated)

Revision:
44:46e25fa1669b
Parent:
42:c4e9c1116af4 
This new version works pretty well, even if the following blob is not as nice as in elasticLoop_OSC. New: fraction rendering / first point wait solved (more regular rendering) / better delay calibration.
