annotate Discovery/Src/data_central.c @ 338:b6a59e93cc91 PressureMeasure_Improvment
Added function to avoid divemode activation during Landing:
Divemode is activated in case of 100mBar difference surface to abiente pressure. This might happen during landing => Added (in sleep mode only) a check for this scenario and increased dive mode activation limit
