I have been reading the source of a few components (from and2 to bldc) but I have not found much documentation on exactly how the magic works.
I am not actually convinced that I really know the difference between a component Parameter and a Pin. PID seems to be documented in different places with the "gains" sometimes called Pins and sometimes Parameters. In a wild moment I wondered about changing the "gains" to Inputs but am not confident on recompiling components. BTW bldc is driving my motors like a champ. I had to resort to trying all "patterns". Looking at the hall outputs and using a battery A-B etc did not find the correct pattern. The other trick that helped was to ignore the encoder (with T parameter) until motor would rotate. There are a lot of things that can be wrong between the patterns and the A/B connections on the encoder!
