if you are able to manage with pic, you may write your sw to measure the signal directly with the pic! , i’ll do this!
i’vent problem with buffer priority, perhaps there are a trigger event before?
which t/div do you have used? have tried with higher t/div? if possible capture first the whole signal with an highest t/div , and after inspect a little portion with a lower t/div
how you recognize that not all signal is recorded?
may you post some picture about the signal?
i’ve managed for investigate on a IR signal, first i’ve captured the whole signal, located the data burst, and the pause, after, i’ve inspected the data with a lower t/div, at single bit level , and finally, ’ i’ve lowered again the t/div for evalute the single Ton/Toff of the IR carrier, and measured it, to know that my ir is a 56 Khz carrier
