hi,<BR>
     I am very impressed with the linistep, but it is more than I need right now.  The only thing I need is simple 200 steps but with a chopper driver so I can run my 5V 1.1A motors with 12V.  I was looking over your schematic and PIC program and I would like to know if I can replace the resistor ladder from pins RB7-6 with a single resistor coming form 5V, just like you have depicted in your 'how it works' page for the 'Operation of the constant current circuit' diagram.  There, you have Rp depicted as a single resistor.  If I am reading your information correctly this should give me 200 Steps only with current chopper control and I could control the stepper sequence from another source like a pc or other controller chip.</BLOCKQUOTE>

Would your .asm code work on a 16F627 or 628? what modifications do i need to make to it to run it on a slightly different device?&quot;

 with comment: 'I don't understand why you think the linistepper would not work with your motor and power supply as it is... They will get hot, and you might want to use a 6 or 9 volt supply instead of 12 to reduce heat, but other than that... This is exactly what the linistepper is designed to do.'

Dear linistep developer(s)<BR>
<BR>
I'd like to ask what modifications I'd have to make to the linistep circuit to drive Nema 34 steppers with a unipolar configuration (obviously, as your cool driver is only unipolar). The datasheet in the link includes the voltages and currents which are, if your lazy like me are, rated voltage: 4.32 volts, current/phase: 2.4A, resistance/phase: 1.8, inductance/phase: 3.3<BR>
<BR>
However, I want to run the steppers at 12V from an ATX power supply, so can you or someone tell me what I need to do to the linistepper circuit to make it drive my steppers at 12V<BR>
<BR>
thankyou for your time in reading this<BR>
<BR>

hi can this controller be conected with an 8 wire stepper motor and worked as a stand alone unit ??&quot;
