wow dude you rock !! ... worked like a charm... here are the changes if
anyone wants to know!
i implemented both suggestions but it seems like the beginBatch/endBatch
actually did the trick!
thanks again!
spi_ = ioio_.openSpiMaster(39, 4, 5, 6, SpiMaster.Rate.RATE_50K);
public void green(int start, int end) throws ConnectionLostException {
try {
for (int i = start; i < end; i++) {
color.clear();
color.r = (byte) 0;
color.g = (byte) 255;
color.b = (byte) 0;
setLed(i, color);
}
ioio_.beginBatch();
try {
spi_.writeReadAsync(0, buffer1_, buffer1_.length,
buffer1_.length, null, 0);
spi_.writeReadAsync(0, buffer2_, buffer2_.length,
buffer2_.length, null, 0);
Thread.sleep(50);
} finally {
ioio_.endBatch();
}
} catch (InterruptedException e1) {
}
}
