Led brightness/expo mode default value?

[openshwprojects]

After merging in #539 ,
/* exponential mode command handler, usage: led_expoMode <0|1|2|3|4>
exponential modes: 0 = Off
1 = 1% min brightness with moderate exponential
2 = 1% min brightness with full exponential
3 = 0.1% min brightness with moderate exponential
4 = 0.1% min brightness with full exponential
*/
I think we should choose a default value for brightness mode on all devices.

Can you guys check which one in your opinion gives best results?
Currently, the default value is 0 = Off

I updated to current firmware and the expo mode doesnt work as i thought, tried all settings. With #447 i can go very down with the brightness.
With the expo mode not.
Very sad

@WiredLife You have convinced me. We're merging #447 soon. I will allow float values for PWMs. I am closing this issue now, let's continue discussion in #447 .
