I am having a hard time modifying HS5245MG to work.
Mechanically, i got all the stops removed. So when turning the servo by hand it is free to rotate continuously. The pot(potentiometer) is 5K across the outside leads(green and red), and the inner (yellow) goes from few ohms to 5k to either side depending on which end of the knob is at.
If I remove the pot altogether I can't get it to move at all. I am pulsing every 20ms, and i tried high state for anywhere from 0.9mS to 2.1mS.
The controller board is not in yet, so I am testing this with a completely different board . I am fairly certain the pulsing is good, as I can get HXT900 moving using the same code. I just replace the leads and put the Hitec servo in place of HXT900.
What I find is that If I take out the pot, but leave it wired, I can get the servo to move by varying the Pot position. I don't even need to pulse the yellow wire at all.
