Bug or feature? was created by Peeeter
Hi,

a value on PPM1 coming in via PPM_IN from a second, foreign student radio has a range of -127 to 128 depending on the stick movement on the foreign radio.

With the following code, I have tried to offset PPM1 into "Virt7" so that Virt7 becomes 0 when PPM1 is -125:

[virtchan7]
name=thron
template=complex
[mixer]
src=PPM1
dest=Virt7
offset=125
curvetype=expo
usetrim=0
points=0,0

However, this does not work, since Virt7 never drops below 25:



Is this just a bug, or am I overlooking something?

Many thanks for your time
Peter

By now I realized that I cannot use the expo curvetype for this, although I don't really understand why not,

Doing it without a curvetype works.
