Avoidance triggering configuration #22
Description
The current TIMER_SAFETY=1 setting turns out to be insufficient and stable situation with an avoidance trigger every second can occur, depending on the current MCU frequency of the Arduino module. This is prevented by using TIMER_SAFETY=2, but this is not necessarily the best solutions. There also is a missing rounding correction in the MCU frequency calibration, so this might just be enough!
