Phil's site lists his L297/8 controller as being for bipolar motors. Reading up on it suggests that the 297 can controller unipolar motors but uses a darlington array instead of the 298.
Yet Gecko's white paper on connections says the 6 wire stepper is identical to the 4 except the 6 has a centre tap. Their diagram shows the 6 wire hooked exactly the same as the 4, with the centre taps un-used.
so my question is, having already bought the 297/298 chip and having a unipolar motor, will it work on Phils 297/8 board if i just ignore the 2 centre taps and pretend its bipolar??
thx
