any one had experience with digital servo ?

what is a code of HK15298B High Voltage Coreless Digital MG/BB Servo ?

Digital servos generally have faster movement and response time than "standard" analog servos. The servos on-board micro controller sends PWM pulses to the servos motor at 50hz in a analog servo, with a digital servo this rate is increased to 300hz. Digital servos will additionally have more torque that a standard servo the same size because torque (and motion) fall off during the low part of the PWM pulse, at 300hz the pulses are coming much quicker without as much down time between pulses. A digital servos biggest advantage over an analog servo is in small, fast movements. A digital servo will have much finer control in very small movements, will be faster in accomplishing them, and will be far more resistant to being pushed out of position.

The downside of digital servos is considerably higher power consumption.

As for actual usage, digital servos are controlled in exactly the same manner as standard analog servos (servo library) so can be used as a replacement for an analog servo in pretty much any case, just battery life will be somewhat reduced due to higher power consumption.

Some digital servos may only rotate 90 deg instead of 180 like typical analog servos. Those servos might be reprogrammed to rotate the usual 180 deg, but a $$$ programmer might be required. YMMV

i was use the same code of analog servo but it not work correctly
