Actually the hardware supports pretty much any kind of phase drive, but the driver does not support it yet. Each HostMot2 stepgen has an up to 6 wide by 16 deep output table and a sequence length register. The table data and sequence length can be loaded by the driver. For example, if you wanted 1X quadrature, a table sequence of 00 01 11 10 and a sequence length of 4 would do it. > > -- > atp > > ------------------------------------------------------------------------------ > Start uncovering the many advantages of virtual appliances > and start using them to simplify application deployment and > accelerate your shift to cloud computing. > http://p.sf.net/sfu/novell-sfdev2dev > _______________________________________________ > Emc-developers mailing list > Emc-developers@lists.sourceforge.net > https://lists.sourceforge.net/lists/listinfo/emc-developers > Peter Wallace Mesa Electronics (\__/) (='.'=) This is Bunny.
