[QUOTE="DACMan1, post: 16949, member: 112"] AFAIK the demo board is rated for 24V max, but should be easy to mod/build a new one. I would search on the microchip site for the board and if you cannot find the sine wave example code, email them. does the motor have three phases feedback? Is it a three phase motor? Another approach could be to just feed it with sinewaves(no fb) it could work, depending on the motor, might just jump around a bit til it is synched... I know people are making DIY turntables using stepper motors (2phase BLDC) and just feeding it with 2 sine waves(out of phase) from a prerecorded CD through an AMP... That's just silly AVNET has a PIC ICD LE for about R627... A JDM programmer can be built for about R10, IIRC it can program the dsPIC family, other DIY programmer usually can't. [/QUOTE]
