#158171 - instant doesn't exist Responding to: ???'s previous message |
There are no "immediate" actions possible. There are longer or shorter latencies involved. All from very short (the time to recharge capacitors on the inputs, the time to react to an interrupt, ...) to very long (the time to finish a previous action and be ready to sample the pin or request variable again, the time needed for debounce, ...)
If you are talking about a keyboard, then you normally need to debounce the input signals, since they will not stabilize instantly. For most purposes, it is enough to be able to handle 10-20 key presses/second which should give you an indication of how much time you have for performing debouncing, and how much time you have for performing trigged actions and be ready to check of new keys are pressed. |
