hi Dave,
well reading a bit more, the problem seems to be that the digital servos receives a different PWM signal from what i read from futaba. While a standard servo receives 1 pulse per cycle the digital one receives 6 pulses (distributed through the cycle) per cycle (both cycles are of 20 milisecs) so in 1 second the standard receives 50 pulses and the digital one receives 300.
On the other hand the RC receiver seems to drive both standard and digital servos with no problem, so maybe there is the trick... i have no clue what may be happening and Futaba doesnt help too much on this.
On the other hand... would you mind adding some comments to the servo script in the registers setting part?
honestly the datasheet is confusing me a lot
thanks in advance
