annotate Discovery/Src/tCCR.c @ 446:f1257a32f2d4 minor_improvments
Introduced configuration header for variant managment:
At the moment several defines are distributed across the code allowing special SW builds (e.g. logging simulated dives). To make these options more transparent and easier to configurate a separate header has been added. With this header an new option for an optical pressure sensor was introduced.
