 The pulse input of the servos is directly connected to IO3 or SPI_INT. Of course, mass is connected to mass. The voltage supply should be about 5\ V. The pulse input of the servos is directly connected to IO3 or SPI_INT. Of course, mass is connected to mass. The voltage supply should be about 5\ V.

 The periodic time results from the internal 16-bit counter for continuous pulse signals: 65536\ *\ 400\ ns\ =\ 26,21\ ms. The periodic time results from the internal 16-bit counter for continuous pulse signals: 65536\ *\ 400\ ns\ =\ 26,21\ ms.
  
-Some servos can definitely cope with 13.1\ ms (unit=200\ ns), you should just try it. The advantage of using the smaller unit is that the servo may be addressed in smaller steps.+Some servos can definitely cope with 13.1\ ms (unit=200\ ns), you should just try it.

 In the following please find a table with some example values. Due to the deviations in the periodic times, the values probably require slight adjustments. In the following please find a table with some example values.
