i2c for synth modules
"ii" came into existence with the creation of teletype to take advantage of the unpopulated i2c header on the monome trilogy modules (white whale, meadowphysics, earthsea).
ii is a protocol layer and configuration which uses the i2c physical bus. (this is to say, ii is a subset of i2c.)
initial documentation by @scanner_darkly
a community created guide goes into further details of the current implementation.
as more modules are added to the ii ecosystem it's become clearer that we should establish a set of standards for the protocol. this will reduce code complexity and create some reusable patterns that will benefit the system.
the goal will be establish a "ii 1.0 standard" document here.
