Also, unless you care about the data coming back, I would use writeReadAsync() and put the entire frame push in a beginBatch() / endBatch() block. Sampling at the trailing vs. leading clock edge has to do with what your slave expects. > > About ANY function I put in the looper does not give my feedback to > android.
