Missing something ... But What ????

[Acetronics2]

Jerson,

I just commented the rolling average line

Ivalue = (Ivalue*9 + Nvalue )/10			' Rolling average

replaced it by

Ivalue = Nvalue

... and it began to work fine @ first run !!!

that is somewhat incredible ...

6 month ago, I wrote a similar program displaying on a couple of 7 segments : everything was fine.
but I didn't use any average ...

I do not understand that because the value was initialized with the average calculated just before entering the display loop ...

Further tests look to show Nvalue = 0 @ first loop ( why ??? we are looping until a conversion result being available ... and it's ages the Pic ADC is stabilised ! ) : value is close to 9/10 Actual value, and then ... minimum value is generally under the minimum, and then not shown !

that's how it should work ... but not why !

I'll try to make further tests ...
