13 years ago --- Quote Start --- If your adc data is a constant (or so) then your accumulator (plus division by 256) will build up from zero gradually then settle at the constant value when sample 255 arrives from stage 255 i.e. it should be within msec not second. during this initial time there is subtraction from zero and so the summed up total divided by 2^8 will be less than constant until all 256 samples are added and divided by 2^8 to equal the constant. Thereafter any new sample arrival is added but last one subtracted leading to same constant. --- Quote End --- @kaz I don't see anything stupid in the simulation. No idea why I am getting this delay now.
