Oh, I just ported the AN908 code from the dspic30f6010 to the dspic30f4011 but without all the extra stuff that was for the development board that it is supposed to be used with. I'm using a mosfet based power section and a control board that I had made quite a while ago. It's in need of revision, but worked when I did the V/Hz test at low current. It spun faster and slower based on the throttle. I had only one of the control boards made at the time because a company had a special deal that they would do anything up to 120 square inches for $25, and that included shipping and no setup fee. But it was a one time thing, and they don't do it more than once. It's the control board in this video:
At about the 8 second point.


The control section pcb/schematic I sent you is the same as the board in the video.

At the 4:35 point there's a picture of the mosfet based power board. It's also needing to be revised, since I accidentally got the stupid silkscreen on the bare copper part, and other little things.

You have it breadboarded?! What did you get working?!?
