is there SIOC variable or something to make servo turn faster?

I wanted to speed up my FLAPS gauge i already change gears it made it little bit faster mainly help with servo limits originally from OC the flaps 30 and 40 were near the limit of 180 i had to set up value 0 for 40 flaps not to brake the servo...

anyways it is however kinda slow say if i test flaps from 0-40 in sim its already at 40 and my gauge is just passing 15.. slooooooooow.. lol

Thanks

Not aware of any way to alter speed of servos with OC. It may be that the sim speed is too fast :-( The only thing I can suggest is to look at the coding to see if it can be optimised, or change the servo to a faster one.

Andy,

A few question:


What kind of A/C?
Do you know the real time the flaps should take 0 to 40? (737-500 : 38.5 ±5 seconds)
Could you show us the SIOC code?
Have you tested the setup using SIOC monitor?


The servo should be more than fast enough:

HS55:

Operating Speed (4.8V): 0.17 sec/60° at no load
Operating Speed (6.0V): 0.14 sec/60° at no load

And combination SIOC / USB Servo card I know is like a rocket so
there must be some trouble with your coding or mechancal configuration.

No i do not know the real time just comparing it to the movement on PMDG737NGX VC
CODE is below its not written by me but works good as far as position. I only eddied what was required the stop values where the needle should stop to indicate whatever flap position
hmmm not sure how to answer this,,, well no... not really it stops where it should and works overall very good its just a lot slower to getting there comparing to needle on the VC



I agree with you Perik servo by itself when i test it with the servo testing program from OC or even the ServoCard program (forgot the name) where i send position is VERY FAST. it will move to position i send in a blink of an eye from flap 0 - 40 probably in a second or less....
servo value for flap up=1020
servo value for flap 40=360
so if i direct send these values to servo it will travel there almost instantly (very fast) like servo should so.

overall its not a big deal servo moves in a nice steady fashion just slower then on VC
I just though maybe there is some variable/statement not sure what to call it to get it to move faster like for example Aceleration 2 used to speed up digits when used with encoder when you move turn encoder fast

Andy,

I don't know the PMDG 737 so I can't do a relevant
test of your code though it looks OK.

Have you tried to run FSInterrogate to see how the Flap Offset ($0BE4 or $0BE0) behaves?
Do the speed and position values correspond to the VC gauge and or your own Servo?

Use these Offset values (one for each flap position) to get correct
scaling in your SIOC code. I think they should correspond to the flap angle deflection.

Just some thoughts ;-)
