Hi：
I need to use log() function in my MCU. I noticed the function is not in ACC4L package, so I simply added subVI and translator to do the job, I thought it was a small job, but I failed to use log() function yet.
The ACC4L will give things like this:
Running interpreter...finished!
Generating downloadable program...Error!
Error in xxx.vi: Arduino function "Arduino Math.lvlib:Log" is not supported.
Can anyone give me a hint? Thanks!

I have to take another path for a quick fix.
|x|<=1,x!=-1, y = (x - 1) / (x + 1)
ln（x）= ln（（1+y）/（1-y））
=2 y（ 1 + y ^ 2 / 3 + y ^ 4 / 5 + y ^ 6 / 7 + …）
It can provide the value I need now.
But the root problem is still there, why are some math function in arduino is not supported in ACC4L？
Last time I checked, functions like exp() are also not supported...
