i try to do a test with the Dcsbios and different sizes of a servos. I don´t get them working, i am sure those 3 wires are correctly connected ( i check from Internet those wire colors) but nothing. I just copy example code and then i change this pin to 5. I try this with external power but nothing. I am not totally green with the DCSbios, i have working cmsp panel etc.etc. And i have been a radioamateur over 30 years, so electronics are not difficult to me understand.
