I don't have a hardware configuration yet, and about the sine/cosine relation I have been reading. The thing is that I don't know how to output this software configuration through the pic. And yes, the pic should do the sensing of the current, throw the corresponding pwm signals to the coils and the combination to make the steps. I want to know if it is possible to program this to the pic via picbasicpro, because I heard of some limitations it has against assembler (in the ccpm modules I read). And if it is possible to do, how to start. Actually I am studying about assembler just to comprehend the code in the application note that I shared in a previous reply.

Best regards and thank you all people for helping .
