No history buffer filling at start, as it was quite slow. The buffer now growths over time, but is used right from the start. |

The battery ADC is pretty jumpy, so more measurements are necessary to have a stable value (oversampling). As ADC measurements take some time, a lot of them slow the system. I reduced the measurements from 4 to 1 (speed increase), but included a history of 16 samples. This history has to be filled at startup, thus rg_system.c had also to be updated.
Changes in voltage now take longer to get recognized, but battery voltage changes are usually quite slow.
