Sorry for responding late. In case it matters, the IOIO is potentially
capable of up to 9 single-precision PulseInput, where every pair of single
precision can form a double precision.
For simplicity, I chose to expose this as 3 single + 3 double, but that's
strictly an arbitrary software decision.
The code that does that is here:
https://github.com/ytai/ioio/blob/master/software/IOIOLibCore/src/main/java/ioio/lib/impl/Board.java#L152
The part that says new int[] {0, 2, 4}, new int[] { 6, 7, 8 },
Says "use modules 0+1, 2+3, 4+5 as double precision and 6, 7, 8 as single
precision. You can change this to whatever other combination you want
(remember that double precision always need to use an even index and would
use up the next index too, and that in total you have 0 through 8).
There's currently no API to make that change, you're need to modify
IOIOLibCore as explained.
