More info, the “bad” board seems to rotate only at speed 12000. But even this is noisy. Anything more or less causes it to just freeze.
My power supply is at 12 V (3A). Could this be a possible reason? What made the other board run the motor smoothly?
This gets weirder, I now have two boards, one works flawlessly over the same code/fw. While the other seems to be choking, it just rotates badly. I’d appreciate if somebody can shed a light on this.
Thanks for the board, it save a lot of work for me…. well almost :-)
Just one question, everything seemed to be working, but I’m not sure how to use the sample code. The motor just runs back and forth calling dspin_run. I expected that it would go one full revolution for this motor (https://www.sparkfun.com/products/9238).
Can this board be used in a pure SPI mode? I only want to use SPI so I’ve connected only the SPI lines with arduino. In fact, in my loop I just do:
I’d appreciate any direction I can get. Thanks in advance guys.
