Real pot need to divide in 4096

[sisoffi]

Hi Pete,

I'm working on a real ASI instruments of maddog. The script made by the previous owner is adapted on a pot range of 0-4096 that he himself had modified in the ini file (and not from the nominal -16k to + 16k). The previous owner not remembering the change from faer in fsuipc.ini,

can you tell me how do I assign the range 0-4096 to the pot?

The Delta need to low value 32 from 256. what does this lower set value mean?

now is :

[Axes]
PollInterval=10
RangeRepeatRate=10
0=2X,256,F,x030066D8,0,0,0    -{ FSUIPC: offset dword set, offset 66D8 }-   ASI SPEED
1=2Y,256,F,x020066D0,0,0,0    -{ FSUIPC: offset word set, offset 66D0 }-     SALMON BUG
2=2Z,256,F,x030066D4,0,0,0    -{ FSUIPC: offset dword set, offset 66D4 }-   BARBER POLE
 

thank you
Simone

 

 

in attach script from sioc.

Simone,

Look at ~page 46 "FSUIPC# for Advanced Users.pdf"  titled:  "Additional parameters to scale input axis values"
My doc is for FSX, if it still holds true for P3D then modify (add to, in red) your .ini as follows & reload the axis assignments (a button on the Axes page) -->

The delta (in blue) is probably to prevent jerkiness.
I am assuming the pot is the feedback loop for the motor/stepper motor. 

[Axes]
PollInterval=10
RangeRepeatRate=10
0=2X,256,F,x030066D8,0,0,0,*0.125,+2048   -{ FSUIPC: offset dword set, offset 66D8 }-  ; ASI SPEED
1=2Y,256,F,x020066D0,0,0,0,*0.125,+2048    -{ FSUIPC: offset word set, offset 66D0 }-     ;SALMON BUG
2=2Z,256,F,x030066D4,0,0,0,*0.125,+2048    -{ FSUIPC: offset dword set, offset 66D4 }-  ; BARBER POLE

thankyou Roman,

but in the axis assignement the offset is correct word offset or not?

in sioc script is $66D0 and in the fsuipc lien is : x020066D0,

Hi Simone, Ramon,

I think Ramon got his calculation the wrong way around, and is converting from +-16k to 0-4096., so it should be

[Axes]
PollInterval=10
RangeRepeatRate=10
0=2X,256,F,x030066D8,0,0,0,*8,-16000   -{ FSUIPC: offset dword set, offset 66D8 }-  ; ASI SPEED
1=2Y,256,F,x020066D0,0,0,0,*8,-16000    -{ FSUIPC: offset word set, offset 66D0 }-     ;SALMON BUG
2=2Z,256,F,x030066D4,0,0,0,*8,-16000    -{ FSUIPC: offset dword set, offset 66D4 }-  ; BARBER POLE

Simone,
In the SIOC file it looks like all the var reads are DWords so change x020066D0 to x030066D0

John,
I dont know.. I am assuming Simone wants 0-4096 from inputs -16384 to 16383 so tried this using the calculator -
-16384 * 0.125 = -2048 + 2048 = 0
16383 * 0.125 = 2047.875 + 2048 = 4095.875

Unless the coffee hasn't quite kicked in yet. 😅

Roman - the inputs are from the pots in range 0-4096 which need converting to the sim accepted range of -16384 to +16383.

More coffee?

Then again I'm not sure - maybe you are correct and I misunderstood...maybe I need more coffee!

John

later: yes, of course, as the script is expecting the 0..4096 range. I originally read that the pot was supplying this range - sorry for the confusion!
