annotate Small_CPU/Src/RTE_FlashAccess.c @ 302:eba8d1eb5bef cleanup-4

bugfix, cleanup: keep both is_ambient_pressure_close_to_surface in sync The CPU1 firmware used 40cm of water pressure, and the RTE used 1m of water pressure to detect between diving and surface state. This is simply wrong, and can lead to small, rounding like, errors. Use 1m water pressure as "official" depth things count as diving. Signed-off-by: Jan Mulder <jlmulder@xs4all.nl>
