You've probably noticed that when using the Analog to Digital converter, the numbers are NEVER stable. At best, the result will always be bouncing back and forth between two numbers.
While it's extremely annoying, there is a reason for it, and the number of times it bounces between those two numbers is actually indicating the values of more bits of resolution that are not included in the original 10-bit result.
This effect can be exploited to increase the effective number of bits in the result.
By taking a number of consecutive samples and averaging the results with a lower divisor, you can get up to 16-bit accuracy from that poor little 10-bit converter.

Re: Scanning encoder debounce on new scope
This can work just fine:
Ioannis Yesterday, 06:571. Set up a timer interrupt at 10ms. Or even at 1ms and after ten int's do step 2.
2. Every interrupt read the buttons into the arrays. You can use a low priority...
