#167498 - Bounce vital to think about Responding to: ???'s previous message |
But you do know what keyboard bounce is?
And you realize what happens with your code if you get a key press that is just long enough for one of your loops to see that something is pressed, but not long enough so all loops will see the press? The remaining pins in the port has zero values in the simulator? The remaining pins in the port has zero values in the real hardware? |
