Turn-key PCB assembly services in prototype quantities or low-volume to mid-volume production runs

Do we need FPGA to count coil windings?

We believe such task can be made by any tiny microcontroller. But if there is a lazy FPGA board lying around then put it to work. And here it is – Cyclone II dev board makes sure coil gets right amount of windings. New coil carcase is fixed to motor. FPGA reads each motor turn using reed switch.

Simple HDL program runs counter and displays current value on seven segment LED display found on board. There is probably one thing missing – motor control that would stop once number of windings is reached. Anyway this is not for mass production of coils and project example may serve as nice material for learning FPGAs.
