#89874 - What have you written ? Responding to: ???'s previous message |
Code for one key is possibly extendable up to 8 keys, on one port - look for our threads on key-debouncing.
More than that, and you really ought to use a matrix of keys, and there are examples in the forum if you search. My current favourite 1-8 key method uses "vertical counters" to hold key states for debouncing. Steve |
