diff Discovery/Src/externLogbookFlash.c @ 452:b90ddf57f7f1 minor_improvments
Added compile variant enabling the reset of profile sample information:
In case the sample ring has an overrun prior to the header ring then header will point to no longer available sample locations causing problems when the no longer existing samples are read. To avoid this also in earlier versions a variant has been added which enables the user to reset the invalid sample information by selecting the problematic dive in the infolog menu and pressing the middle button.
Added function which confirms consistency of dive log settings:
Meaning last dive and dive header are valid at startup. Repair and find lastDiveID are only called in case a inconsistency is detected
