My code for ADC button handling, it works, but can it be slimmed down?

[CuriousOne]

Thanks!
My main concern is number of variables needed...

[richard]

code snippets do not provide any where near the required info to provide a meaningful answer, not even one var definition is even provided

for a meaningful answer
1 how often is routine called
2 is it called on a regular timed basis
3 how responsive does it need to be

the minimum key data necessary would be a count to detect a debounced press a bit to indicate a new press detected and a bit to indicate
the press has been acknowledged and acted on provided the right conditions exist

[CuriousOne]

1. At least 10 times per second.
2. Yes
3. As responsive as any other device, where user presses key and expects immediate feedback.

[richard]

1. At least 10 times per second
if right>100

so button has to held for ten seconds till you get a response ?

As responsive as any other device

not in my book, i doubt the thing is working after 300mS

2. Yes

like how regular how often really

[CuriousOne]

No.
I mean keyboard is polled at least 10 times per second.
This is general interactive device control, with direct feedback
like your TV remote.
