  1. Thanks, I didn't think the registers matched the tutorial, but I see that they do now! My vhdl isn't as good as my verilog, which isn't very good either I'm afraid . And to make matters worse I had to massage the file in order for it to synthesize on my wishbone-less design! (Who would've thought wishbone needs not only CS/WE but also CYC and STB to latch data?!) Regarding the calculations, if I understand correctly, the system clock (in mhz) goes to the SMTBASE register, while the step frequency (in microseconds) is written to SMPERIOD, correct? There's a note on the old page about a header file containing macros for the above calculations (I assume also for the prescaler).. is that in the Arduino / Papilio sketch?
  2. Hi, I stumbled upon Gadgetforge as I was looking for a simple stepper motor design to play with on a cypress psoc board. I wish I would have known about the Papilio before I bought it.. the cypress psoc board is a bit more complicated for a newbie. Anyways, I understand the code at the old site , is outdated compared to Papilio.cc / github.com.. however I can't seem to find the referenced verilog & vhdl files anywhere: http://gadgetforge.gadgetfactory.net/gf/project/stepper_core/ (BPW5005_1axis_Stepper_Controller_Core.v ? BPW5005_1axis_Stepper_Controller_Core.vhd ?) The only file that looks close, the registers don't seem to match the old tutorial.. https://github.com/GadgetFactory/ZPUino-HDL/blob/master/zpu/hdl/zpuino/contrib/papilio_stepper/papilio_stepper.vhd Are the old files still available anywhere? I'd be eternally grateful if someone could post it here, or PM / email it (my username @ lycos dot com). Thanks! Ben
