Further to my previous post, I did some more experimentation I set calibration as s4.calibration(640,2400,640,2470,2200) Then manages to get to servo to move through 180 degrees as follows servo.angle(0) went to left extreme servo.angle(45) went to midpoint - 90 degrees servo.angle(90) went to right...

Has anyone got this to work correctly? I have an STM32 based pyboard and cannot get the builtin Servo module to turn to an angle less than 0 degrees. A typical SG90 servo has a midpoint of 1500 microsec, 90 degrees at 2500, -90 at 1000. servo.calibration() shows values that correspond to the above. ...
