#171488 - Another idea...
Responding to: ???'s previous message
Hi Akhil,

first, there's no need to do this by the help of interrupts. You can also manage it by periodically polling the corresponding port lines.

More, I don't think, that multiple pressings of the "mode" button is a good idea. Operators tend to press the buttons too fast later, which will result in trouble.

Why not changing the mode by keeping the "mode" button pressed and simultaneously pressing the "up" and "down" buttons to select the "A", "B" or "C" first? You can have three LEDs then, one for "A", one for "B" and one for "C". Keeping the "mode" button pressed and pressing the "up" and "down" buttons makes one LED after the other turning on and by this showing you which of "A", "B" or "C" is selected.
