Hello,
I'd like to create programs using accelerometer on many platforms, and
there are many things that I do not understand.
1) why (test on a Android smartphone) does in this exemple, only 2 out of
3 parameters are moving with my movement, although 3 are configured in the
code ?
*(it"s one of the examples you give, but I can't find it anymore in the new
documentation. It was in the "using built-in sensors" section). *
import("stdfaust.lib");
// parameters
x0 = hslider("x0",0.5,0,1,0.01) : si.smoo;
y0 = hslider("y0",0.5,0,1,0.01) : si.smoo;
y1 = hslider("y1",0,0,1,0.01) : si.smoo;
q = hslider("q[acc: 0 0 -10 0 10]",30,10,50,0.01) : si.smoo;
del = hslider("del[acc: 0 0 -10 0 10]",0.5,0.01,1,0.01) : si.smoo;
fb = hslider("fb[acc: 1 0 -10 0 10]",0.5,0,1,0.01) : si.smoo;
// mapping
impFreq = 2 + x0*20;
resFreq = y0*3000+300;
// simple echo effect
echo = +~(de.delay(65536,del*ma.SR)*fb);
// putting it together
process = os.lf_imptrain(impFreq) : fi.resonlp(resFreq,q,1) : echo :
ef.cubicnl(y1,0)*0.95 <: _,_;
2) (test on a Android smartphone) if I change acc with gyr and choose
good parameters, nothing happens and the sensors do not work at all.
3) How do you link the easy [acc: a b c d e] with the fact that you want to
use the X, Y or Z axis ?
4) in Faust Playground (whichi is html based) on my Laptop, you provided
the possibility to EDIT the "blocks" (instruments or effects) and choose if
I want or not use the accelerometer... But, whatever I choose, it doesn't
change anything in the code. (and I did'nt find any parameters that could
be impacter by this).
Anyway, whether I choose accelerometer or not, it doesn't work on a
laptop.So, what is the use of it, and how does it work ?
Finally, am trying to understand how does the accelerometer parameters
work. Am I correct, if I say these statements :
- the accelerometer does not work on Html, so not on my laptop, although
you created an interface especially for that
- the accelerometer could work on iOS if I were an Apple Developper... so,
for me, it's impossible to test it.
- the accelerometer works on Android ... but "sometimes" it doesn't work
???
I'm sure I missed something.... could you help me ?
Thanks a lot.

PS : I must thank Julius for his last answer. Sorry for not having doing so
before ...
