/* This file is only a thin shell that includes the correct RTC implementation
|
|
* for the selected STM32 family. The correct file cannot be selected by
|
|
* the make system because it needs the intelligence that only exists in
|
|
* chip.h that can associate an STM32 part number with an STM32 family.
|
|
*
|
|
* The STM32 F4 RTC differs dramatically the F1 RTC. The F1 RTC is a simple
|
|
* battery-backed counter; the F4 RTC is provides broken-out data/time in BCD
|
|
* format.
