The following functions are experimental since 0.2.0 and not tested a lot by me.
|
||||
They allow to use a higher resolution while not using floats.
|

They allow to use a higher resolution while **not using floats**.
|
||||
Goal is to keep the footprint of the library small.
|

|

- **bool setResolution(uint8_t resolution = 9)** sets the internal resolution to 9, 10, 11 or 12 bits.
