How to get Data from different loops saved in one single file

If you want to save data from different loops to one file, we hopefully can assume that all loops run at the same rate.


No unfortunately they do not. I just checked and my sensor runs at roughly 165Hz but from my 2 NI Measurement cards (with these i measure my voltage/current) i get a rate of 4Hz. Which is weird. Maybe it is best just trying to make 3 different files...


How do sensors and cards define a rate? Typically your program should be in control of timing (else it's "the tail wagging the dog"!). How important is their timing? Would it be sufficient to read the sensors at 4Hz?

How strict are the timing requirements?

 

How should the file entries look like? timestamp? type of sensor? etc.
