[SOLVED] Direction of Motor Rotation from 3 Hall outputs.

[technochrat]

Hello All,

I have a problem.I need to find the direction of rotation of 5 motors from their Hall sensor outputs (3 outputs each).

I understand that Comparing the pattern on the sensor outputs will give its direction,ie each direction will give a repeatable sequence.
I think this can be done with the help of a simple microcontroller like a PIC16.
Please correct me if I am wrong.

Basically I will have a minimum of 15 inputs and possibly 5 outputs (1 for each motor).So that the logic level determines the direction of rotation.
What are the possible ways of implementing this?
Microcontrollers,CPLDS?

Well,i guess i will have to go with the Microcontoller option.

Will be using the CCP modules on PIC MCUs for speed measurement.
Havent decided how to implement the direction part yet.
