Hi
It's important to have the feedback from the force sensor as fast as possible to allow the system to responce immediately. By the time, the sampling rate have to be high to avoid of lost counting from tha hall sensor.
So I guess the magnet is mounted on a rotating shaft - well how fast is this shaft rotating? 1-2 kHz is rather fast. I have seen 2-stroke motors for RC model airplanes rotate at this speed, but it's a rare speed with substantial shaft mass.
Do you need to export the force sensor and hall count in real time to matlab simulink or do you need to export at a certain event like: The force is above a critical value?
