annotate Discovery/Src/externCPU2bootloader.c @ 448:f7c66593ab82 minor_improvments
Added compile switch to show voltage parallel to charge status percantage
Show aging of bottle sensor data by change of text color:
Permanent connection is shown white. After two minutes timeout the text is shown red to indicate that the value shall no longer be trusted
