Almost, the 'hi' and 'low' parts are not constant as in the ASCII Art, but show some modulation looking somewhat like sinus half-waves. > Is the motor still in "qh" mode? Yes. > What are the in_type and out_type parameters showing? bldc.0.in_type is 1 bldc.0.in_type is 0 I have no idea if this is correct or not. But I'm sure you know. :-) By the way. I only found a man page on bldc and the pages in the wiki, is there any documentation that I'm missing. > You can compare the values to the state-machine in the source code > and see what stage the component is sticking at. Uh.. OK, I'll take a look. Thank you. Flo ------------------------------------------------------------------------------ How ServiceNow helps IT people transform IT departments: 1.
