What is the smallest amount of time duration that the timer object measure in pd? Specifically, can it measure values in microseconds?

@Polygraphovich I don't know this topic much, but from memory this is the external that allows the smallest time interval:

https://git.iem.at/pd/iemlib
--------------- t3 - time-tagged-trigger ---------------------
----------- a time-tag is prepended to each message -----------
----- so these objects allow a sample-accurate access to ------
---------- the signal-objects t3_sig~ and t3_line~ ------------
t3_bpe time tagged trigger break point envelope
t3_delay time tagged trigger delay
t3_metro time tagged trigger metronom
t3_timer time tagged trigger timer

Cheers~

@Polygraphovich also, as you can set the timer interval in samples......... http://puredata.info/docs/manuals/pd/x2.htm
from chapter 2.4.4 onwards......

Thanks guys,

I tried using the t3_timer object and I think I might be getting somewhere. My overall aim is to measure the amount of time that a trigger pin is on, connected to an ultrasonic sensor through firmata and an arduino board. I was trying to compute this by sending a t b b from the trigger to the two inlets of a timer object. I don't think I can do the same with the t3_timer object though.
@whale-av, thanks for the lead. I think I better read up about block size if I need to deal with small time intervals.

The [timer] object can measure any duration that can be expressed within the precision of a single-precision floating point number.
