Just be aware...
Since the Propeller is not interrupt driven there's a chance that at 2400 steps per rotation with a 20MIPS cog you might fall behind at high RPM. Unlike the ARM using an interrupt it won't generally freeze. It will just miss transitions.
I actually do have a Propeller based PropASC+ here.
For the sake of this test I decided against attempting this initially.
I know these quadrature chips work so I'd rather not introduce user code where I don't need to.
The code needed to do this in a Parallax Propeller is readily available.
I am still working on this. Also building a CNC machine. Also writing code for another project so bear with me. So far no major issues.
I'm a couple thousand into FIRST expenses so far this year so gotta keep all the things rolling.
