Hello, i have great problems in measuring an analog value and/or a counter. The frequency has to be 20 Hz!!! That means, i want to receive 20 times per second some analog values.
Attention! The values has to be sampled with exactly 20 Hz! Allways, under all conditions!
With a LabJack it works bad, because there is no triggering possible and i have to stream. So i receive a huge amount of data wich has to be scanned for the right value at the right time and my PC is nearly paralysed. The LabJack can't be triggered external.
My question is: is it possible to trigger (external 20 Hz signal) the arduino? Is it possible to send instructions to the arduino? Is the arduino able to execute the instructions during the 20 Hz stream?
Thanks for reading!
