grandad Posted October 29, 2012 Share Posted October 29, 2012 Hi,Just received my SD (thanks guys & gals!) but cannot figure out why, when I connect a servo to it the servo (any servo) winds fully clockwise and won't budge, no matter what values I set in the parameters of the SD.The SD is talking fine to my PC and power is applied (well that's obvious!) The reset jumper is on.Servos I have tried are Futuba S3003 and e-sky ESRV0A (this is a miniature servo from a small helicopter) They all work fine when used in an RC setup.I cannot seem to find any info on the pulse timings needed for these servos.Can anyone help please? I feel sure it will be something simple that I am overlooking ;o)Martin Link to comment Share on other sites More sharing options...
grandad Posted October 30, 2012 Author Share Posted October 30, 2012 OK, well I have received details from Futuba with regard to the spec of a servo and it falls within the default parameters of the SD as you would expect.I have reset the SD as per the manual, tried supplying the SD with voltages between 9v and 12v but still cannot get ANY control of the servo!I can read (get) the config etc. from the SD using the SD utility but nothing I do works - has anyone any idea where I am going wrong, or is the SD a DOA?Martin Link to comment Share on other sites More sharing options...
grandad Posted October 30, 2012 Author Share Posted October 30, 2012 Oh Boy, oh boy, oh boy - do I feel stupid Looking around the SD board for any dry joints etc (sorry Dan!) the light bulb in my head came on.I had the servo plugged in THE WRONG WAY AROUND!! Ahhh well, all working fine now - rush to get my first animated skull finished now, I've had it on the side for a while awaiting the SDMartin (with much egg on face!)

k6ccc Posted October 30, 2012 Share Posted October 30, 2012 (edited) Damn electronics stuff that only works when plugged in correctly Welcome to the club (not with servos in my case, but with some other stuff)..Make sure you order the egg for your face in a fashion that you like to eat - makes cleanup easier.Glad you got it working.
