view Small_CPU/Src/uart.c @ 429:7f351c25608a ImprovmentNVM_2
Marked possible code improvment for future activities:
parameters stored in the settings were not trusted. LastDive ID and Sample index are usually calculated at startup. This calculation could be avoided, nevertheless the implementation works => only TODO
Removed function without effect:
Calling writeblock with legth 0 has no effect
