Am I on right track if I say this is whole steps? A 5 wire unipolar stepper motor needs 4 datapins and having each go high subsequently while the other three go low, will perform this action seen in the video, right? (Going high means opening a corresponding transistor, which will activate corresponding coil in the stepper motor.)
But most code for unipolar show a pattern of 8 steps, not 4:
0 1 2 3 4 5 6 7 D0 HI HI LO LO LO LO LO HI D1 LO HI HI HI LO LO LO LO D2 LO LO LO HI HI HI LO LO D3 LO LO LO LO LO HI HI HI
So the even steps would be the whole steps, while the odd steps would be the added half steps. If I'm on right track, do all 5 wire stepper motors behave like this? Or are there motors uncapable of handling the half steps? Or are there motors requiring this half step pattern?
I haven't found confirmation for my assumptions. I'm working on hijacking the stepper motors on an old typewriter to turn it into a plotter and the motors are 5 wire unipolar. I'll be actually hijacking the "drivers", too, which are two IC:s with 7 darlingtons and 7 diodes in each. Since it will be a plotter, I'm most interested in achieving a good resolution by having half stepping or even micro stepping work.
