oh also spi is fixed. "spi_ = ioio_.openSpiMaster(new DigitalInput.Spec(4,
Mode.PULL_UP), new DigitalOutput.Spec(5),
new DigitalOutput.Spec(3),
new DigitalOutput.Spec[] { new DigitalOutput.Spec(2) },
new SpiMaster.Config(Rate.RATE_1M, false, true));" worked better than
"spi_ = ioio_.openSpiMaster(4, 5, 3, 2, SpiMaster.Rate.RATE_1M);" in our
situation.
The latter produced double information.
