I have some steppers (bipolar 4-wires) from printers I would like to
test.
This is the motor I'm trying to test.

I bought some Toshiba LDMOS bipolar drivers TB6598FN.
Typical application. This is my schematic exactly the same.

The motors are getting a regulated 12Vdc and the driver gets 5Vdc.
My questions.
From the datasheet for best performance my control signals should be
about 400Hz? 50% or less duty?
How should my control signals be for forward stepping?
The truth table just shows EN1&2 high,IN1&2 LOW. If I pulse IN1&2
they will go from forward to reverse and back again.
What should the sequence be to the four control pins for simple
forward stepping?
I'll be using a PIC probably just 12f508 for my control signals.
