hello ,
i progammed a code for time measuremnts with a light barrier, where the endtime is displayed on a WIFI linked android smartphone.
For the time-measurement of start - and endtime i use the function millis() from the wiringpi library.
My Question is : How accurately is my measurement ?( I display the time in seconds with 3 decimal places.)
Does the function millis() of the library wiringpi Pi really use the Raspberr pi3 1,2 GHz clock signal ?
What is the frequency of the interrupt thats behind the function millis() in this case ?
Does millis() work for the raspberry pi 3 in other way because of the 1,2GHz Clock as it works for arduino unoR3 for instance with 16Mhz Clock ??
I would be very happy if someone could explain this to me .
