Hall sensor application example for S32K1xx

Dear Officer,

We are using 2 Hall sensor to measure the DC motor rotation direction and speed based on S32K118.

Do we have similar application source code for such application?

(We are not using Matlab model based design and 2 hall sensor is separated slightly so to have "lead" or "lag" in pulse detection to get the rotation direction.)

Thanks and best regards

He Wei

Hi,

I am not aware of such application using dual hall sensors.

You can find several solutions using single Hall sensors for position detection and speed detection, like
