Long / short press button...but reading ADC

[fratello]

Thanks again for support !
Unfortunately I can not solved this ... because "For accurate reading of ADC I use bubble-sort algoritm, how it's presented on this forum."
No matter what I tried ; it's available ONLY short press.
Regards !

What if you start a timer?

DT's routines could tell you how long a button is pressed.

Thanks !
I thought about this ... Should I use this ?
I don't think I have "space" ...

[richard]

can you explain what you are trying to achieve ?
do you in fact have multiple buttons each with a different R4 ?
did you try my second example ? is it even relevant if not what needs to happen differently ?

at this stage I still can't see how an array sorting routine is in any way useful for detecting button presses long or short .
why not post the code for what have you tried

dt_elapsed will not run on a12f675

Fratello,

I would suggest downloading and looking at the original for 18F PICs here:

Tried hard to solve this problem, using a timer ... but without succes .
Any advice will be very appreciated !

Why do you insist on sorting the ADC readings? What problem is that trying to solve?

I'd get rid of the "bubble sort" and try starting with Richard's code.
