not all receivers work with all servos, i have a spektrum srs4210 4 channel rx and it will only work with digital servos, normal servos just go crazy and stutter if i try and use them in it, the manual also states that regular servos will not function with it.I believe that all hobby servos use the same communications protocol, whether digital or not. If that were not true then "special" RC receivers would be needed, which is not the case in my experience. Hence, the "servo" command will work just fine.
even with the AVC turned off it sends standard servos crazy, presumably as the frame rate is so fast but that AVC itself is pretty good lolIt's not that digital servos are anything special but the Spektrum srs4210 receiver is, as it has something called Active Vehicle Control.
" AVC – Active Vehicle Control
AVC™ technology is the newest Spektrum™ RC innovation from Horizon
Hobby. This Spektrum stabilization system adds a whole new level of control
to your RC driving experience. AVC technology utilizes sensors to adjust
steering and throttle output, providing you with a more stable and
controlled driving experience.
NOT ICE: You must use digital servos with the SR4210 receiver.
Using analog servos will reduce the performance of the system
and may cause analog servos to overheat."
The frequency difference between an analog servo and a digital servo is internal to the servo and has nothing to do with the frame rate, except in the case of specialized / proprietary systems servos that might use a different frame rate. If you have one of the servos and a Picaxe why not just take the time to hook them up and do some actual testing?Digital servos have higher frequency than analog servos, see: http://www.futaba-rc.com/servos/digitalservos.pdf
Increase the frequency is possible in X2 (servant [45536], 1.75). How do in M2?

I think I may have just confused the twoThe frequency difference between an analog servo and a digital servo is internal to the servo and has nothing to do with the frame rate
Why would everything be solved, when there does not seem to be any problem at all ?Everything would be solved if it were possible picaxe M2, with the SERVO command, change the frequency.
Absolutly, though a lot of people get taken in by the belief that since digital servos do drive (internally) the motor at a higher frame rate, then the controlling servo pulses also have to be at the higher rate ............. big mistake.The frequency difference between an analog servo and a digital servo is internal to the servo and has nothing to do with the frame rate,
Read very carefully, I have seen that data sheet quoted often, it causes a great deal of confusion, it actually says;Digital servos have higher frequency than analog servos, see: http://www.futaba-rc.com/servos/digitalservos.pdf
