Hi Jason, Ytai, 2 years later...
@Jason, did you find a solution at your problem ? Cause I'me currently doing exactly the same stuff with ioio and sharp and I get exactly what you described... I'm a bit confusing with the data sheet of sharp sensor. I don't know if it meaning milliseconds...microseconds.. And how to do it just with a IOIO board without any arduino. @Ytai, without an arduino, you meant it's impossible to do this with ioio cause it's too slow ? Thanks. Lo.
