A mini block with two buttons and a hub unit.
-
Good afternoon. I am from Russia and I apologize for my English. I have ATOM3S. I connected it to the ATOMIC ABC(SKU:A130) port. I connected the I/OUT HUB(SKU:U041-B) to the red port(I2c). And I connect the thumbnail double buttons to the hub (SKU:U025). I learned how to poll them and get the status of the button. But only THE BLUE BUTTONS. And I can't let go of the red button. I can't see her condition and I don't have a polling unit. How do I do this?
