view Small_CPU/Inc/tm_stm32f4_otp.h @ 610:ae7f8333c900
Added access to logbook marker data:
In previous version event data could only be stored in memory but read back and usage in the OSTC itself was not supported. After the events like a marker set by the diver may be retrieved from the log.
Added visualization of markers to T3_Profile view
